Camera is an optical instrument that forms images in a way most like human eyes.
Explanation:
The eye consists of a small spherical globe of about 2 cm in diameter, which is free to rotate under the control of 6 extrinsic muscles. Light enters the eye through the transparent cornea, passes through the aqueous humor, the lens, and the vitreous humor, where it finally forms an image on the retina.
In case of a digital camera, CCD is used known as charged coupled device. CCD is actually in the shape of array or a rectangular grid. It is like a matrix with each cell in the matrix contains a censor that senses the intensity of photon. When light falls on the object , the light reflects back after striking the object and allowed to enter inside the camera which is then stored by CCD in the form of electric signals.
Similarities between eye and a camera:
Cornea and Lens - The cornea is the “cap” of the eye. This transparent (like clear jelly) structure sits to the front of the eye. The lens of a camera is also transparent (glass) and sits at the front of the body. Both allows light to enter and have spherical curvature.
Iris and aperture -The aperture is to the camera as the iris is to the eye. Both control the amount of light allowed to enter the eye or camera.
Retina and Film - The retina sits at the back of the eye and collects the light reflected from the surrounding environment to form the image. The same task in the camera is performed either by film or sensors in digital cameras.

A microscope forms images most similar to the eye due to the use of lenses and focusing techniques.
A microscope forms images in a way most like your eye. Both the eye and the microscope utilize lenses to form images. The method of focusing in the eye, through changes in the curvature of a lens, differs slightly from most optical instruments but is more similar to how a microscope forms images.
What does the graph of acceleration vs. time look like for something going a
constant velocity?
O
A. A downward sloping straight line
O
B. A vertical line.
O
C. A horizontal line.
O
D. A curving line with upward slope.
Acceleration vs time graph would show C. A horizontal line (at zero)
Explanation:
The acceleration of an object is the rate of change of velocity of the object:
[tex]a=\frac{\Delta v}{\Delta t}[/tex]
where
[tex]\Delta v[/tex] is the change in velocity
[tex]\Delta t[/tex] is the time interval
For an object moving at constant velocity,
[tex]\Delta v = 0[/tex]
This means that also the acceleration is zero:
[tex]a=0[/tex]
And therefore, if we plot the graph of the acceleration vs time, we would see a horizontal line (cosntant acceleration) at zero (because the acceleration is zero).

What is the escape velocity on the Venus ? Venus' mass 4.90*10^ 24 kg and radius is 6.86 * 10 ^ 6 * m
The escape velocity on Venus is 9761 m/s
Explanation:
The escape velocity from a planet is the speed that an object on the surface of that planet must have in order to completely escape the gravitational field of the planet.
Mathematically, it is calculated as
[tex]v=\sqrt{\frac{2GM}{R}}[/tex]
where
G is the gravitational constant
M is the mass of the planet
R is the radius of the planet
For Venus, we have:
[tex]M=4.90\cdot 10^{24}kg[/tex] is the mass
[tex]R=6.86\cdot 10^6 m[/tex] is the radius
Substituting, we find the escape velocity on Venus:
[tex]v=\sqrt{\frac{2(6.67\cdot 10^{-11})(4.90\cdot 10^{24})}{6.86\cdot 10^6}}=9761 m/s[/tex]

Donna stretched a spring to increase its length. Nearby in an electrical device, a positive charge attracted a negative charge. Which statement is true about the spring and the negative charge?
A. They both experienced contact forces.
B. They both experienced non-contact forces.
C. The spring experienced a contact force and the charge experienced a non-contact force.
D. The spring experienced a non-contact force and the charge experienced a contact force.
C. The spring experienced a contact force and the charge experienced a non-contact force
Explanation:
In physics, there are two types of forces:
Contact forces: contact forces are those where a contact between the objects involved is needed, in order to have the force. Examples of contact forces are the force of friction (the contact between the two surfaces is needed), or the elastic force in a spring (in fact, the spring needs to be physically in contact with something that stretches it)Non-contact forces: non-contact forces are those where no contact is needed between the objects, so they can be exerted at a distance. Examples are the gravitational force (two masses exert a force on each other even from a distance) or the electric force (two charges exert a force on each other even from a distance).Therefore, in this example:
The spring experiences a contact forceThe two charges experience a non-contact forceSo the correct answer is
C. The spring experienced a contact force and the charge experienced a non-contact force

A 1.000kg block of phosphorus-32, which has a half life of 14.3 days, is stored for 100.1 days. At the end of this period, how much phosphorus-32 remains?
Answer: 0.0078 kg
Explanation:
The answer can be found using the Radioactive Half Life Formula:
[tex]A=A_{o}.2^{\frac{-t}{h}}[/tex]
Where:
[tex]A[/tex] is the final amount of phosphorus-32
[tex]A_{o}=1 kg[/tex] is the initial amount of phosphorus-32
[tex]t=100.1 days[/tex] is the time elapsed
[tex]h=14.3 days[/tex] is the half life of phosphorus-32
Solving with the given data:
[tex]A=(1 kg)2^{\frac{-100.1 days}{14.3 days}}[/tex]
[tex]A=0.0078 kg[/tex] This is the remaining amount of phosphorus-32
Given a 1.000kg block of phosphorus-32 with a half-life of 14.3 days, we can calculate the remaining amount after 100.1 days using exponential decay and the half-life formula.
Explanation:The question pertains to the concept of radioactive decay, particularly concerning the half-life of an isotope. The block of phosphorus-32 being referred to undergoes radioactive decay, and its half-life, or the time required for half of the substance to decay, is 14.3 days.
To find out how much remains after a certain number of days, we can use the equation N = N0*(1/2)^(t/T), where N is the final amount, N0 is the initial amount, t is the elapsed time, and T is the half-life. In this case:
N0 = 1.000 kg (initial amount)T = 14.3 days (half-life)t = 100.1 days (elapsed time)
Inserting the respective values into the formula, we find how much phosphorus-32 remains at the end of this period.

Explain how two dangerous elements can form a compound that is edible
Two dangerous elements can form a compound that is edible known as "NaCl salt".
Explanation:
Sodium and chlorine are two very dangerous elements. As the reaction between sodium and water is extremely violent and chlorine is a very toxic gas. But combination of these elements result into a harmless product with unique properties like it is edible and dissolves without exploding in water.
In sodium chloride reaction the atoms of sodium interact with chlorine atoms. Sodium will donate an electron (by becoming positively charged) to acceptor chlorine (which become negatively charged) as given in following reaction
[tex]N a+C l_{2} \rightarrow N a C l[/tex]
As sodium and chlorine are very keen to achieve noble gas configuration by completing an octet on donating and accepting an electron respectively.
The dangerous two elements which are compounded together to form an edible compound are sodium (Na) and Chlorine (Cl) salt.
What are the two dangerous elements that can form a compound that is edible?The two dangerous elements which are combined to form an edible compound are sodium and chlorine. We know that sodium is exploding material that can explode in water.
Similarly chlorine gas is also a very toxic gas but when we combine both of them then the compound formed will be an edible salt. This compound can easily dissolve in water.
When sodium and chlorine are exposed to each other for the reaction the positive atoms of the sodium gets combined with the negative atoms of the chlorine so the compound of NaCl is formed
[tex]Na^{+}+Cl^{-}=NaCl[/tex]
As sodium and chlorine are very keen to achieve noble gas configuration by completing an octet on donating and accepting an electron respectively.

explain why solar eclipses do not occur every time the moon revolves around earth
Answer:
the moon, earth, and sun all must be in alignment ; not just the moon and earth
Final answer:
Eclipses occur when the Moon, Earth, and Sun align, but the Moon's orbit inclination causes eclipses to be rare occurrences due to the specific alignment needed for an eclipse to happen.
Explanation:
Eclipses occur when the Moon, Earth, and Sun are directly lined up in the full Moon (lunar eclipse) and new Moon (solar eclipse) positions. Eclipses do not occur every month because the Moon's orbit is inclined about 5 degrees so usually the Moon is little above or a little below the direct line of sight from the Sun.
The reason for the rarity of eclipses lies in the inclination of the Moon's orbit. This inclination causes the Moon to mostly be positioned either above or below the Earth during a new moon, preventing a solar eclipse every month.
While the Moon revolves around the Earth close to once a month, the specific alignment required for an eclipse to occur is met only occasionally due to the intricate orbital dynamics between the Earth, Moon, and Sun.

When two object P and Q are supplied with the same quantity of heat, the temperature change in P is observed to be twice that of Q. The mass of P is half that of Q. The ratio of the specific heat capacity of P to Q
Explanation:
Specific heat capacity
It is defined as amount of heat required to raise the temperature of a substance by one degree celsius .
It is given as :
Heat absorbed = mass of substance x specific heat capacity x rise in temperature
or ,
Q= m x c x t
In above question , it is given :
For Q
mass of Q = m
Temperature changed =T₂/2
Heat supplied = x
Q= mc t
or
X=m x C₁ X T₁
or, X =m x C₁ x T₂/2
or, C₁=X x 2 /m x T₂ (equation 1 )
For another quantity : P
mass of P =m/2
Temperature= T₂
Heat supplied is same that is : X
so, X= m/2 x C₂ x T₂
or, C₂=2X/m. T₂ (equation 2 )
Now taking ratio of C₂ to c₁, We have
C₂/C₁= 2X /m.T₂ /2X /m.T₂
so, C₂/C₁= 1/1
so, the ratio is 1: 1

water, what happens to the entropies of the
molecules in the spoon and the water
molecules?
A spoon increase, water increase
B spoon increase, water decrease
C spoon decrease, water increase
D spoon decrease, water decrease
Answer:
C
Explanation:
Spoon decrease, water increase
Final answer:
When a hot spoon is placed in cold water, the spoon's entropy decreases and the water's entropy increases as heat is transferred from the spoon to the water. So the correct option is C.
Explanation:
If a hot spoon is placed in a glass of cold water, the entropy of the molecules in the spoon decreases, and the entropy of the water molecules increases. This is because entropy can be thought of as the measure of disorder within a system. The hot spoon transfers heat to the colder water, resulting in a decrease in temperature and therefore a decrease in disorder of the spoon's molecules, leading to lower entropy. Conversely, the cold water gains heat, increasing the disorder of its molecules, thus increasing its entropy. So, the correct answer is (C) spoon decrease, water increase.

[tex]T=2\pi \sqrt{\frac{m}{k}}[/tex]
where
m is the mass
k is the spring constant
In this problem, we have:
k = 88.7 N/m is the spring constant
The system makes 15 oscillations in 9.24 s: therefore, the period of the system is

If a car is going 25 mph on the street and suddenly stops, a book on the seat flies off
of the seat and hits the floor. Why did the book continue to move after the car
stopped?
The book continue to move due to its inertia
Explanation:
We can answer this question by using Newton's first law, which states that:
"When an object is moving with constant velocity (or it is at rest), it will continue moving with constant velocity (or will stay at rest) unless acted upon an external unbalanced force".
This law is also known as law of inertia.
If we apply this law to the situation in the problem, we notice that:
- Before the car stops, the book is moving with constant velocity (25 mph) together with the car
- When the car stops, there are no external forces acting on the book, which is free to continue its motion: so, the book will continue moving at 25 mph forward, due to its inertia. The book will be eventually stopped when it hits the floor (because the floor applies an unbalanced force on it).

A ball is dropped off the side of a bridge. after falling 1.55 s, what is its velocity?
Answer:
-15.19 m/s
Explanation:
The 1D kinematic equation for velocity is the v = v0 * at.
In this case, v is the final velocity (what we're after), v0 is the initial velocity, a is the acceleration, and t is the time elapsed.
v0 is 0 because at 0 seconds we are just releasing the ball.
a is the acceleration due to gravity as no other factors are specified.
t is the change in time.
v = 0 * -9.8 m/s^2 * 1.55 = -15.19 m/s.

A 0.1 kg apple drops 2m hitting a spring. The spring deforms 0.1m.
What is the spring constant ?
Answer:
392 N/m
Explanation:
We know that the total mechancial enery will be conserved from when the apple drops to when it hit the spring. Therefore, we can set the potential energy of the apple equal to the elastic potential energy of the spring.
PE = mgh and SE = 1/2kx² — PE is the initial potential energy of the apple and SE is the elastic potential energy of the spring.
mgh = 1/2kx². (.1)(9.8)(2) = (1/2)(k)(.1²), solve for k. k = 392
1. A poorly tuned Yugo can accelerate from rest to a speed of 28 m/s in
20 s.
a) What is the average acceleration of the car?
b) What distance does it travel in this time?
a)The average acceleration of the car is [tex]1.4 \mathrm{m} / \mathrm{s}^{2}[/tex]
b) The distance travelled is 560 m
Explanation:
a) Acceleration is defined as the rate of change in velocity per unit time. So it can be obtained by measuring the ratio of speed to time.
[tex]Average acceleration =\frac{\text { Final speed - Initial Speed }}{\text { time }}[/tex]
Since here the initial speed was zero and final speed is given as 28 m/s, then time is given as 20 s. So,
[tex]\text {Acceleration}=\frac{28-0}{20}=\frac{28}{20}=1.4 \mathrm{m} / \mathrm{s}^{2}[/tex]
b) As the speed is given as 28 m/s, then
[tex]\text {distance}=\text { Speed } \times \text { Time }=28 \times 20=560 \mathrm{m}[/tex]
So the distance travelled is 560 m and average acceleration is [tex]1.4 \mathrm{m} / \mathrm{s}^{2}[/tex].

The mass of the second car is 1434.21 kg
Explanation:
Using law of conservation of momentum,
[tex]m_{1} u_{1}+m_{2} u_{2}=\left(m_{1}+m_{2}\right) v[/tex]
Given:
[tex]m_{1}[/tex] = 1090 kg
[tex]u_{1}[/tex] = 11 m/s
[tex]u_{2}[/tex] = 0
v = 4.75 m/s
We need to find [tex]m_{2}[/tex]
When substituting the given values in the above equation, we get
[tex](1090 \times 11)+\left(m_{2} \times 0\right)=\left(1090+m_{2}\right) 4.75[/tex]
[tex]11990=5177.5+4.75 m_{2}[/tex]

Explanation:
The period of the pendulum is the time taken for it to complete 1 full oscillation. This means that the pendulum moves this way for it to be 1 oscillation:
P ➟ Q ➟ R ➟ Q ➟ P
Since the pendulum only moved back to midpoint Q and not back to P, it has completed less than 1 oscillation.
Let each movement to the next section be 1 unit.
So 1 oscillation - 4units
In this case, the pendulum moved 3 units.
3 units ----- 3s
1 unit ----- 3÷3
1 unit ----- 1s
Thus 1 full oscillation would take 4(1)= 4s
Therefore, period of pendulum= 4s.

A 81.9 kg person stands on her toes. The surface area of her toes in contact with the ground is only 0.00210 m^2. How much pressure is exerted between her toes and the ground, IN ATMOSPHERES?
So, the pressure exerted by the person on the ground (in units of atm) is close to 0.38 atm.
IntroductionHi ! I'm Deva from Brainly Indonesia and I will help explain something about solid pressure material. Remember the definition of pressure in solids is "The amount of force felt per unit area of pressure". So, based on the meaning, it is embodied in the equation :
[tex] \boxed{\sf{\bold{P = \frac{F}{A}}}} [/tex]
[tex] \boxed{\sf{\bold{F = P \times A}}} [/tex]
[tex] \boxed{\sf{\bold{A = \frac{F}{P}}}} [/tex]
With the following conditions :
P = solid pressure (N/m²)F = the force that the object has (N)A = Area of pressure (m²)However, always remember, if the object is a stationary mass and is affected by gravity, then the value of F can be calculated by :
[tex] \boxed{\sf{\bold{F = m \times g}}} [/tex]
With the following conditions :
m = mass of the object (kg)g = acceleration due to gravity (m/s²)Problem SolvingWe know that :
m = mass of the object = 81.9 kgg = acceleration due to gravity = 9.8 m/s²A = Area of pressure = 0.00210 m² >> See, in the problem there is the word "toes" which means this area has covered the whole (his/her ten of toes)What is ask :
P = solid pressure = ... atmStep by step :
Calculate the pressure value, meanwhile, the unit is N/m²[tex] \sf{P = \frac{F}{A}} [/tex]
[tex] \sf{P = \frac{m \times g}{A}} [/tex]
[tex] \sf{P = \frac{81.9 \times 9.8}{0.0210}} [/tex]
[tex] \sf{P = \frac{802.62}{0.0210}} [/tex]
[tex] \sf{P = 38,220 \: N/m^2} [/tex]
Don't forget to convert N/m² to atm, 1 atm = 101,325 N/m²[tex] \sf{P_{(atm)} = \frac{38,220}{101,325}} [/tex]
[tex] \sf{P_{(atm)} = \frac{38,220}{101,325}} [/tex]
[tex] \boxed{\sf{P_{(atm)} \approx 0,38 \: atm}} [/tex]
So, the pressure exerted by the person on the ground (in units of atm) is close to 0.38 atm.

Explanation:
The acceleration of an object is the rate of change in velocity, and it is given by the equation
[tex]a=\frac{v-u}{t}[/tex]
where
v is the final velocity
u is the initial velocity
t is the time needed for the velocity to change from u to v
For the roller coaster in this problem, we have
u = 4 m/s
v = 22 m/s
t = 3 s

If I put one hand in hot tap water and the other in cold tap water then both in the same warm tap water what will happen
Answer:
you will feel warm
Explanation:
beacause your body will get the warm from warm water tap..
Final answer:
When hands are first placed in hot and cold water and then both into warm water, they will perceive different temperatures due to temperature adaptation. This demonstrates that the sensation of warmth or coolness is relative and is interpreted by the nervous system.
Explanation:
If you were to place one hand in hot tap water and the other in cold tap water and then both in the same warm tap water, you would experience a phenomenon known as temperature adaptation. This occurs because your sensory receptors adapt to the initial temperature exposure. So, when you then place both hands in the warm water, the hand that was in the hot water would feel the warm water as cooler, while the hand that was in the cold water would perceive the warm water as hotter.
This is a clear demonstration that the sensation of 'hotness' or 'coolness' is relative and depends on prior conditions that the sensory receptors in your skin have adapted to. This sensory adaptation helps explain how our nervous system interprets different stimuli depending on preceding conditions. It is not that the 'hotness' or 'coolness' resides in the mind as an idealistic concept, but rather, the interpretation of these sensations is a neurological process that occurs in the brain.
