Answer:
ligma
Explanation:
An object is placed 9.5 cm in front of a convex spherical mirror. Its image forms 3.2 cm behind the mirror. What is the radius of curvature of the mirror? Show all work.
Using the mirror formula.
1/v + 1/u = 1/f
1/9.5 + 1/3.2 = 1/f
1/f = 3.2 + 9.5 / 9.5 * 3.2
1/f = 4.82 cm
Radius = 2f
Radius = 2 x 4.82
Radius = 9.64 cm
Answer:
Radius of curvature, R = 9.64 cm
Explanation:
It is given that,
Object distance, u = -9.5 cm
Image distance, v = 3.2 cm
We have to find the radius of curvature of the mirror. The relationship between focal length and the radius of curvature as R = 2 f where f is the focal length of the mirror.
Using Mirror's formulas as :
[tex]\dfrac{1}{v}+\dfrac{1}{u}=\dfrac{1}{f}[/tex]
[tex]\dfrac{1}{3.2}+\dfrac{1}{-9.5}=\dfrac{1}{f}[/tex]
f = 4.82 cm
And radius of curvature of the mirror becomes, R = 9.64 cm. Hence, this is the required solution.
distinguish the differences between diamagnetic and paramagnetic materials. Give examples of each type of material
Answer:
Paramagnetic materials are attracted by external magnetic fields whereas diamagnetic materials are repelled. Paramagnetic materials have at least one unpaired electron in the system, but diamagnetic materials have all their electrons paired.
Explanation:
Diamagnetic materials are weakly repelled by magnetic fields due to induced dipoles aligning oppositely, while paramagnetic materials are weakly attracted due to their unpaired electrons aligning with the field. Copper and gold are examples of diamagnetic materials, whereas aluminum and magnesium are examples of paramagnetic materials.
Diamagnetic and paramagnetic materials respond differently to magnetic fields due to their distinct atomic properties.
Diamagnetism is characterized by a weak repulsion from magnetic fields. This occurs because the atoms in diamagnetic materials have no permanent magnetic dipole moments. When an external magnetic field is applied, it induces magnetic dipoles within the atoms. These induced dipoles align oppositely to the applied field, creating a repulsive effect. When the field is removed, the induced magnetic effect vanishes.
Examples of diamagnetic materials include copper, gold, and silicon.
Paramagnetism involves a weak attraction to magnetic fields. The atoms in paramagnetic materials have unpaired electrons, which results in permanent magnetic dipole moments. When an external magnetic field is applied, these dipoles tend to align with the field, enhancing its effect. However, this alignment is temporary and disappears when the external field is removed.
Examples of paramagnetic materials include aluminum, magnesium, and platinum.
Which of the following statements are true about bar magnets?
a. The direction of the magnetic field are considered to flow from the south pole to the north pole around the outside of the magnet.
b. If a bar magnet is cut in half, two new magnets will be formed each with a south and north pole
c. The north pole of a bar magnet will align itself with the South Pole of the earth.
d. All magnets have a similar magnetic field as a bar magnet.
Answer:
b. If a bar magnet is cut in half, two new magnets will be formed each with a south and north pole
Explanation:
As we know that magnetic field lines always originates from north pole of magnet and then terminate at south pole.
Also all magnets must have two poles (i) North pole (ii) South Pole
now if we break a magnet into two parts then this magnet will again form two new poles on the opposite sides so that each half will again have two different poles of magnet
So here we can say that when a bar magnet is cut into two parts then each part will behave like a new magnet.
so correct answer will be
b. If a bar magnet is cut in half, two new magnets will be formed each with a south and north pole
Final answer:
Bar magnets have a magnetic field direction from the north pole to the south pole externally, and cutting a bar magnet in half results in two new magnets each with a north and a south pole. The north pole of a magnet aligns with the Earth's magnetic South Pole.
Explanation:
The truth about bar magnets can be understood by examining their properties and behaviors:
Statement a is incorrect. The direction of the magnetic field lines around a magnet is from the north pole to the south pole externally, and it's the opposite inside the magnet.Statement b is correct. When you cut a bar magnet in half, you end up with two new magnets, each with a north and a south pole.Statement c is correct as the north pole of a bar magnet will align with the Earth's magnetic South Pole, which is geographically near the Earth's North Pole.Statement d is overly general. While it is true that all magnets have a north and south pole and the field lines form closed loops, their magnetic field shapes can vary based on the physical shape of the magnet.A radioisotope has a half-life of 5.50 min and an initial decay rate of 7200 Bq.

An atom with an imbalance of electrons to protons is
An ion is an atom that is electrically charged by gaining or losing one or more electrons.
To understand it better:
An atom has a nucleus with electrons around it and has a neutral charge. When an electron is added or detached, this atom is electrically charged, that is, it ceases to have a neutral charge and becomes an ion.
In this sense, there are two types of ions:
-Anions: ions negatively charged, by the gain of electrons in the atom.
-Cations: ions positively charged, by the loss of electrons in the atom.
Final answer:
An atom that has an unequal number of electrons and protons is called an ion. This imbalance creates an ion with a net positive or negative charge, called a cation or an anion respectively.
Explanation:
An atom with an imbalance of electrons to protons is known as an ion. Atoms are normally electrically neutral because they have an equal number of protons and electrons. However, when atoms gain or lose electrons, they become ions, which can be either positively or negatively charged. This imbalance in charge leads to electrical forces that can cause the ion to interact with other ions or molecules.
A positive ion, called a cation, is formed when an atom loses one or more electrons. Conversely, a negative ion, referred to as an anion, is created when an atom gains electrons. The process of an atom becoming an ion is called ionization, and these ions play a crucial role in chemical reactions and the formation of compounds.

Which example best illustrates the transfer of energy between two waves? A) A buoy rises in the water as a boat speeds past. B) A basketball rebounds from the backboard during a missed shot. C) An egg that rolls off the counter falls and breaks on the floor. D) A car that rear ends another car causes damage to both vehicles.
Answer:
A.
Explanation:
Answer: Option A
Explanation: Waves (mechanical and electromagnetic) can transfer energy when they impact into something.
When a boat speeds in the water, the boat itself pushes water around it generating mechanical waves in the water, those mechanical waves now travel on the surface of the water. When those mechanical waves impact the buoy, the waves also move the buoy, and now the buy is in a "wave-like" motion (you can model the movement of the buoy as a mechanical wave, that goes up and down), so this is a good example of energy transfer.

Gel electrophoresis is a technique used to separate nucleic acids by their _______.
Gel electrophoresis is called to the technique used by scientists for analytical purposes, in life sciences laboratories to separate macromolecules (DNA, RNA, and proteins from various sources).
The process consists of separating the molecules according to their size and electric charge. This is done with a gel (a gelatinous substance extracted from seaweed, called agarose) of controllable porosity placed in an ionic buffer environment. This is how the gel acts as a molecular sieve that separates larger molecules from the smaller ones, because each molecule has different size and charge and will move through the gel at different speeds.
That is, the smaller molecules move more quickly through the gel while the larger ones are left behind.
Gel electrophoresis is a technique used in biology to separate nucleic acids such as DNA based on size. The negatively charged nucleic acids move through a semisolid gel when an electric field is applied, with smaller molecules moving faster than larger ones. The fragments can be observed as bands on the gel, their distance from the top depending on their size.
Explanation:Gel electrophoresis is a technique used to separate nucleic acids, such as DNA fragments, based on their size. This separation occurs because nucleic acids, which carry a negative charge, move through a semi-solid, porous gel when subjected to an electric field. They load near the gel's negative electrode and move towards the positive one at the opposite end. The speed at which these molecules move depends on their size, with smaller ones moving faster through the gel's pores than larger ones. This difference in migration rate enables the separation. When observed with fluorescent or colored dyes, distinct fragments of nucleic acids appear as bands at specific distances from the top of the gel, based on their size.

C) It had a much higher temperature in the past. D) It was discovered by Penzias and Wilson in the early 1960s. E) It appears essentially the same in all directions (it is isotropic)
Microwave background radiation was accidentally discovered by Penzias and Wilson on 1964. This is a form of electromagnetic radiation that is present in the whole universe and completely fills it (it is isotropic).
It is the leftover radiation from the big bang.Its frequency belongs to the microwaves range and is one of the main demonstrations of the of the Big Bang theory model.
It is important to note the Big Bang occurred 400,000 years before the events related to the microwave cosmic radiation, this means the Big Bang occurred first.
The incorrect statement about cosmic background radiation is that it's a mixture of radiation from many independent sources like stars and galaxies. It is actually the thermal radiation left over from the Big Bang.
Explanation:The statement B) It is the result of a mixture of radiation from many independent sources, such as stars and galaxies, is not true regarding cosmic background radiation. Cosmic background radiation is not a mixture of radiation from different sources, but actually the thermal radiation leftover from the 'Big Bang'. It's effectively the 'echo' or 'afterglow' of the Big Bang, and it appears essentially the same in all directions, which means it's isotropic.
It has a temperature of approximately 3 degrees Kelvin (just above Absolute Zero), as discovered by Arno Penzias and Robert Wilson in the early 1960s. This radiation was much hotter in the past, but has cooled as the universe expanded over billions of years.

You have two steel solid spheres. sphere 2 has twice the radius of sphere 1. part a by what factor does the moment of inertia i2 of sphere 2 exceed the moment of inertia i1 of sphere 1?
The moment of inertia [tex]\( I_2 \)[/tex] of sphere 2 exceeds the moment of inertia [tex]\( I_1 \)[/tex] of sphere 1 by a factor of 4.
The moment of inertia I of a solid sphere is given by the formula:
[tex]\[ I = \frac{2}{5} m r^2 \][/tex]
Where:
- m = mass of the sphere
- r = radius of the sphere
Given that sphere 2 has twice the radius of sphere 1, we can express the radius of sphere 2 as 2r, where r is the radius of sphere 1.
Now, let's consider the moment of inertia for each sphere:
1. Sphere 1 (with radius r):
[tex]\[ I_1 = \frac{2}{5} m r^2 \][/tex]
2. Sphere 2 (with radius (2r):
[tex]\[ I_2 = \frac{2}{5} m (2r)^2 \][/tex]
We can simplify [tex]\( I_2 \)[/tex] as follows:
[tex]\[ I_2 = \frac{2}{5} m (4r^2) = \frac{8}{5} m r^2 \][/tex]
Now, to find the factor by which [tex]\( I_2 \)[/tex] exceeds [tex]\( I_1 \)[/tex], we divide [tex]\( I_2 \)[/tex] by [tex]\( I_1 \)[/tex]:
[tex]\[ \text{Factor} = \frac{I_2}{I_1} = \frac{\frac{8}{5} m r^2}{\frac{2}{5} m r^2} \][/tex]
[tex]\[ \text{Factor} = \frac{\frac{8}{5}}{\frac{2}{5}} = \frac{8}{2} = 4 \][/tex]
So, the moment of inertia [tex]\( I_2 \)[/tex] of sphere 2 exceeds the moment of inertia [tex]\( I_1 \)[/tex] of sphere 1 by a factor of 4.

Which resistors in the circuit must have the same amount of charge passing through each second?
Answer:
Option B) C and D
Explanation:
The amount of charge passing through a resistor each second corresponds to the definition of current, so the problem is asking "which resistors have the same amount of current".
Let's keep in mind that:
- When two resistors are in series (=they are connected into the same branch of the circuit), the current flowing through each resistor is the same
- When two resistors are in parallel (=they are connected into different branches), the potential difference across each resistor is the same
Looking at the previous definitions, we have to find the two resistors in the circuit that are connected in series. We see that resistors C and D are in the same branch, so they are in series: therefore, the current flowing through resistor C and D is the same.

A neutral atom of tin (Z = 50) has 69 neutrons. (a) How many protons does it have? (b) What is its mass number?
Answer:
Protons = 50
Mass number = 119
Explanation:
A neutral of tin, Sn, has a Z value of 50 and neutrons are 69.
Z is the atomic number. The atomic number is equal to number of protons or number of electrons in an atom that is neutral i.e:
Z = PROTONS = ELECTRONS
So the number of protons = 50 since Z is 50
>>>>>>>>>>>>>>>¦
The bulk of the mass of an atom is concentrated in the nucleus. To calculate mass number, we simply sum all the elementary particles in the nucleus i.e protons and neutrons. These particles are called the nucleons.
Mass number (A) = P + N
= 50 + 69

The color of an opaque object is the same as the light that is
a) transmitted b) absorbed c) reflected d) all of these
Answer: reflected
A material is opaque when it does not allow light to pass through itself.
In other words:
When light illuminates an opaque object, no ray passes through it, as most of the light is reflected or absorbed by the object.
In this context, the main characteristic of this type of objects is that the color of the material depends on the light it absorbs. It means that depending on its chemical composition they can absorb certain wavelengths (colors) and reflect others.
Therefore, the color we see in an object is the light it reflects. For example, if we see a red table, this means that when light iluminates it, this table absorbed all the visible wavelengths, except the red, which is the light that is reflected and perceived by our eyes.

Find the de broglie wavelength of an electron in the ground state of the hydrogen atom.
de Broglie wavelength (λ) is given by the equation
λ = h/p
where h=Planck’s constant whose value is 6.62 x 10^(−34) joule-seconds and
p = momentum of the particle(here electron)
In terms of kinetic energy(E) momentum(p) can be written as,
p=(2mE)^1/2
where m=mass of the particle.
Hence λ becomes
1 λ = h(2mE)^-1/2
Given here, E = 13.6 eV = 13.6×1.6×10^-19 joule
m(mass of electron)= 9.1×10^-31 kg
Putting these values in equation (1) we get ,
λ =0.332×10^(-9) meter
=3.32×10^(-10) meter
=3.32 Å
De Broglie wavelength of an electron in the ground state of the hydrogen atom is about 3.33 × 10⁻¹⁰ m

[tex]\boxed{\lambda = \frac{h}{mv}}[/tex]
where:
λ = wavelength ( m )
h = Planck's Constant ( 6.63 × 10⁻³⁴ Js )
m = mass of object ( kg )
v = velocity of object ( m/s )
Let us now tackle the problem !
[tex]\texttt{ }[/tex]
Given:
energy of the ground state of the hydrogem atom = E = 13.6 eV = 2.176 × 10⁻¹⁸ J
Asked:
wavelength of electron = λ = ?
Solution:
Firstly , we will calculate the speed of the electron :
[tex]E = E_k[/tex]
[tex]E = \frac{1}{2}mv^2[/tex]
[tex]v^2 = 2E \div m[/tex]
[tex]\boxed{v = \sqrt{ 2E \div m } }[/tex] → Equation A
[tex]\texttt{ }[/tex]
Next, we will use the formula of The Broglie's Wavelength:
[tex]\lambda = \frac{h}{mv}[/tex]
[tex]\lambda = \frac{h}{m\sqrt{ 2E \div m }}[/tex] ← Equation A
[tex]\lambda = \frac{6.63 \times 10^{-34}}{9.11 \times 10^{-31} \sqrt{ 2 \times 2.176 \times 10^{-18} \div 9.11 \times 10^{-31} }}[/tex]

Describe how electric potential energy, kinetic energy, and work change when two charges of opposite sign are placed near each other.
potential energy is energy that is stored and kinetic energy is energy in motion and I believe that if you try to put them together it might not work potential energy would be a minus in the side for kinetic energy would be a plus sign
As opposites attract, Potential energy is pulled to Kinetic energy. The force from Kinetic energy is working on potential energy over a distance. This means the potential energy (q )started with is being converted into kinetic energy (Q). Potential energy is accelerating and picking up speed.
What are potential energy and kinetic energy?Potential energy is what we call stored energy. Kinetic energy is a form of energy that an object or a particle has by reason of its motion.When the electric field does positive work on a charge (as in the example above), the potential energy of the field decreases as the tank is depleted of energy. Conversely, the potential energy increases when the electric field steals energy by doing negative work (by slowing down a charge, for instance).To learn more about potential and kinetic energies, refer to: https://brainly.com/question/18556454
