B.microwave ovens
C.the internet
D.FM radio

Answers

Answer 1

Amplitude modulation is used in AM radio.

Answer is A.

Answer 2

Answer:

Amplitude modulation is used in AM radio.

Explanation:

Information signals must be transported between a transmitter and a receiver on some form of transmission medium. However, information signals rarely find a suitable way to transmit. Therefore, modulation is defined as the process of transforming information from its original form to a form more suitable for transmission, and is performed on the transmitter in a circuit called a modulator.

AM means modulated amplitude or amplitude modulation; it consists in varying the amplitude of a carrier wave of relatively high frequency according to the amplitude of the modulating signal (information). Frequencies that are high enough to radiate efficiently through an antenna and propagate through free space are commonly called radio frequencies.

AM was the first technique that was used to make radio.

Then amplitude modulation is used in AM radio.

B.
4.4 m/s2
C.
5.4 m/s2
D.
9.8 m/s2

Answers

Answer:

D!

Explanation:

Using the formula F = ma, you plug in 4.9 for F (force), and 0.5 for m (mass), then solve for a (acceleration).

Answer:

9.8 m/s^2

Explanation:

F=ma

The force is 4.9 N

The mass is 0.5 kg

The acceleration is what we are trying to figure out.

(Now, plug into the equation)

4.9= 0.5a

Take 4.9/0.5 to find the value of a, which is 9.8m/s^2

2. How much work does gravity do in causing a 6 kg hammer to fall to the ground from a
height of 10 m?​

Answers

Answer:

Therefore, gravity does 588.6 Joules of work in causing the 6 kg hammer to fall 10 meters.

Explanation:

Gravity does work by exerting a force on the hammer over a certain distance. We can calculate this work using the formula:

Work = Force x Distance (where force is parallel to the direction of movement)

In this scenario:

Force = Gravitational force acting on the hammer (Weight of the hammer)

Distance = Height fallen

Force:

We can calculate the gravitational force (weight) using the formula: Weight = Mass x Gravity

Mass of the hammer (m) = 6 kg

Gravity (acceleration due to gravity) = 9.81 m/s² (approximately)

Weight = 6 kg * 9.81 m/s² = 58.86 N (Newtons)

Distance:

Distance (d) = 10 m

Work done by gravity:

Work = Force x Distance = 58.86 N * 10 m = 588.6 Joules

Therefore, gravity does 588.6 Joules of work in causing the 6 kg hammer to fall 10 meters.

A force of 5 N accelerates an object. The object’s mass is 50 g. What is the acceleration of the object? (Formula: F=ma)

0.01 m/s2
0.1 m/s2
10 m/s2
100 m/s2

Answers

Answer:

100 m/s²

Explanation:

First, convert to SI units:

50 g = 0.050 kg

Now plug into the formula:

F = ma

5 N = (0.050 kg) a

a = 100 m/s²

A force of 5 N accelerates an object. The object’s mass is 50 g. Then acceleration of the object is  100 m/s².

The formula linking force, mass, and acceleration is given by

F = ma,

Where F = the force applied to the object,

m = the mass of the object,

and a =the resulting acceleration.

In this case, the force is 5 N and the mass is 50 g, or 0.05 kg (remember to convert grams to kilograms).

Now, we can solve for the acceleration using:

a = F/m

a = 5 N / 0.05 kg

a = 100 m/s²

So the acceleration of the object is 100 m/s².

Answers

Answer:

[tex]L_A = 9 L_B[/tex]

Explanation:

The formula that relates the luminosity of a star (L) to its radius (R) and the temperature (T) is

16. A 6 kg block is falling toward a spring located 1.8 m below. If it has a speed of 4 m/s at first,
what will be the maximum compression of the spring? Assume the spring constant is 2000 N/m
[6 marks][1 mark for Comm]​

Answers

Answer:

Maximum compression of the spring: [tex]\rm 0.423\; m[/tex].

Explanation:

Let [tex]x[/tex] be the maximum compression, in meters, of the spring.

What's the initial kinetic energy of this block?

The initial velocity [tex]v[/tex] of the block is [tex]\rm 4\;m\cdot s^{-1}[/tex].The mass of the block is [tex]\rm 6\;kg[/tex].Initial [tex]\displaystyle \mathrm{KE} = \frac{1}{2} \;m\cdot v^{2} = \rm \frac{1}{2} \times 6\times 4^{2} = 48\;J[/tex].

What's the final kinetic energy of this block?

The block would have come to a stop by the time the spring reaches its maximum compression. [tex]v = 0[/tex]. As a result, the final kinetic energy of the block shall also be zero.

Let the initial height of the block be zero.

The height of the block will be [tex]\rm -1.8\;m[/tex] by the time it reaches the top of the spring. However, the height of the block will become even more negative as the spring compresses. If the maximum compression of the spring is [tex]x[/tex] meters, the height of the block will be [tex]-(1.8 + x)[/tex] meters by the time the spring reaches its maximum compression.

The change in the height of the block will thus be [tex]-(1.8 + x)\;\mathrm{m}[/tex] relative to the initial position of the block. The change in the block's potential energy due to gravity will be:

[tex]\Delta \mathrm{GPE} = m\cdot g\cdot \Delta h = 6\times 9.8 \times (-(1.8 + x)) = -105.948- 58.86\;x[/tex].

The mechanical energy of an object is the sum of its kinetic energy and its potential energy. What will be the change in the mechanical energy of the block?

[tex]\text{Change in Mechanical Energy} \\ = \text{Change in KE} + \text{Change in PE} \\ = (0 - 48) + ((-105.948- 58.86\;x) - 0)\\ = (-153.948 - 58.86\;x)\; \text{J}[/tex].

The block has lost [tex](153.948 + 58.86\;x)\; \text{J}[/tex] of energy as it travels from its initial position to the place where the spring is most compressed. Energy conserves. Those energies are transferred to the spring. Assume that there's no energy loss in this process. All those [tex](153.948+ 58.86\;x)\; \text{J}[/tex] would have become the elastic potential energy of the spring.

On the other hand, it is assumed that the spring is compressed by a distance of [tex]x[/tex] meters. By Hooke's Law, the elastic potential energy of the spring will be:

[tex]\displaystyle \text{Elastic Potential Energy} = \frac{1}{2} \; k\cdot x^{2} = \frac{1}{2}\times 2000 \times x^{2} = 1000\; x^{2}\;\text{J}[/tex].

There are thus two expressions for the Elastic Potential Energy of the spring:

[tex](153.948+ 58.86\;x)\; \text{J}[/tex] from the conservation of energy, and[tex]1000\; x^{2}\;\text{J}[/tex] by Hooke's Law.

The two expression shall be equivalent. Equate the two expressions and solve for the compression of the spring, [tex]x[/tex].

[tex]153.948+ 58.86\;x = 1000\; x^{2}[/tex].

[tex]1000\; x^{2}- 58.86\;x - 153.948 = 0[/tex].

[tex]\displaystyle x_{1} = \frac{-(-58.86) +\sqrt{(-58.86)^{2} - 4\times 1000 \times (-153.948)}}{2\times 1000} = \rm 0.423[/tex].

[tex]\displaystyle x_{2} = \frac{-(-58.86) +\sqrt{(-58.86)^{2} - 4\times 1000 \times (-153.948)}}{2\times 1000} = -0.364[/tex].

Consider the expression for the height of the block when it is at the top of the spring and when the spring reaches maximum compression:

Height of the block at the top of the spring: [tex]\rm -1.8\;m[/tex];Height of the block when the spring reaches maximum compression: [tex]-(1.8 + x) \; \text{m}[/tex]. This height will be [tex]\rm -2.2\; m[/tex] if [tex]x_{1}[/tex] is correct, and [tex]\rm -1.4\; m[/tex] if [tex]x_{2}[/tex] is correct. The block compresses the spring and will be below its initial position at the top of the spring. Therefore, [tex]x > 0[/tex] and only [tex]x_{1}[/tex] is correct.

The maximum compression of the spring will be 0.423 meters.

IDENTIFY the common types of precipitation. COMPARE and CONTRAST them.


Answers

The most common types of precipitation are:

- rain

- snow

- hale

The rain comes in liquid form. In order for the rain to occur, the temperature in the upper parts of the troposphere should not be too low, thus the condensation of the water vapor can only go from gaseous to liquid form. The rain occurs in the lower latitudes, as well as in the mid-latitudes mostly from spring to autumn.

The snow occurs in the higher latitudes and in the mid-latitudes during winter. In order for the snow to form, the temperatures in the upper parts of the troposphere should be below the freezing point, so the water vapor crystallizes into small ice crystals.

The hale occurs in the warmer period in the mid-latitudes, and occasionally in the lower latitudes. The hale is formed when during the condensation of the water vapor into liquid form, the air mass encounters much lower temperatures below the freezing point. This results in the formation of large crystals that fall on the surface in the form of frozen, circular-shaped pieces.

7. How much thermal energy is absorbed when 10.0 g of ice at 0.0 degrees C changes phase to liquid water at 0.0 degrees C? The molar mass, M, of water is 18.02 g/mol and the theoretical heat of fusion, Hfus, of water is 6.01 kJ/mol

Answers

Answer:

3.34 kJ

Explanation:

FIrst of all, we need to calculate the number of moles corresponding to 10.0g of ice. This is given by

[tex]n=\frac{m }{M_m}[/tex]

where

[tex]M_m = 18.02 g/mol[/tex] is the molar mas

m = 10.0 g is the mass

Substituting

[tex]n=\frac{m}{M_m}=\frac{10 g}{18.02 g/mol}=0.555 mol[/tex]

Now we know that the heat of fusion is

[tex]H_{fus}=6.01 kJ/mol[/tex]

so the thermal energy needed to fuse the ice is

[tex]Q=n H_{fus} = (0.555 mol)(6.01 kJ/mol)=3.34 kJ[/tex]

Answer:

DescriptionA storm surge, storm flood, tidal surge or storm tide is a coastal flood or tsunami-like phenomenon of rising water commonly associated with low pressure weather systems, the severity of which is affected by the shallowness and orientation of the water body relative to storm path, as well as the timing of tides.

A wall of water that is pushed ashore is a storm surge. So, the correct option is A.

What is Storm surge?

A coastal flood or tsunami-like event of rising water known as a storm surge, storm flood, tidal surge, or storm tide is frequently linked to low-pressure weather systems like cyclones. It excludes waves and is calculated as the rise in the water level just above typical tidal level.

Extreme coastal as well as interior flooding may be the result of the seawater's pulse when it reaches the coast. Storm surge can sometimes be much more destructive than the thunderstorms that produce it.

An anomalous increase in water caused by a storm that is higher than the expected astronomical tides is known as a storm surge. Storm tide, which is referred to as the increase in water level brought on by a storm surge and an astronomical tide, shouldn't be confused with storm surge.

Therefore, the correct option is A.

If some electrons are transferred from object A to object B,
A. Object A will have a positive charge
B. Object A will have a negative charge
C. Object B will have a positive charge
D. B and C

Answers

Answer: A. Object A will have a positive charge.

Explanation: If the number of protons and electrons are the same, their net charges cancel each other out, and you have a neutral charge. If electrons are transferred to another object, the amount of positive charge will outweigh the amount of negative charge. As a result, you are left with an overall positive charge in object A. Meanwhile, object B is now negative.

Final answer:

When electrons are transferred from object A to object B, object A will become positively charged (option A) due to the loss of negatively charged electrons. This makes the answer A. Object A will have a positive charge.

Explanation:

If some electrons are transferred from object A to object B, the correct answer is A. Object A will have a positive charge. This is because electrons have a negative charge, and removing them from an object leaves that object with an excess of positive charge in the form of protons (which are positively charged and present in every atom). Object B, receiving the electrons, will become negatively charged since it gains additional negative charges.

With reference to the information provided:

Ball 1 (analogous to object A) will have a positive charge if it loses electrons.Ball 2 (analogous to object B) will have a negative charge if it gains electrons.If a positively charged object is in contact with an uncharged object in a closed system, the uncharged object will become positively charged.

what is the net force if one person is pushing on a box with 60 N of force to the right and another person is pushing on the box with 30 N of force to the left?

Answers

Answer:

The net force on the box is 30 N to the right.

Explanation:

To find the net force on the box, we must add all of the forces together. In order to do this successfully, we must establish a positive and a negative direction. Let’s say that the positive direction is towards the right and the negative direction is towards the left.

Knowing this, we can set up the following equation:

Net force = F1 + F2

Now we can substitute in our known values for the forces given in the problem.

Net force = 60 N + (-30 N)

If we simplify and solve, we get

Net force = 60-30 = 30 N

Since we established the right as the positive direction, we know that the answer is 30 N to the right. If we think about this problem conceptually, this answer makes sense because the 30 N force to the left cancels out 30 N of the force towards the right, because they are acting in opposite directions.

Answers

Is halved. A 6Ω resistor connected to a voltage source which voltage is decreased from 12V to 6V the current passing through the resistor is halved.

The key to solve this problem is applying Ohm's Law V = R I, clearing I from the equation, we obtain I = V/R. Then, the current is directly proportional to the voltage and inversely proportional to the resistance.

V = 12V and R = 6Ω

I = 12V/6Ω = 2A

V = 6V and R = 6Ω

V = 6V/6Ω = 1A

As we can see the current is halved if the voltage descreased from 12V to 6V

The correct option is

(c) is halved.

Given a 6Ω resistor and the voltage is decreased from 12V to 6V

Ohm's Law:

Ohm's law states that the current (I) is directly proportional to the voltage (V) and inversely proportional to the resistance (R). That is

V= I/R

here, according to the question

initially, V = 12V and R = 6Ω

so I = 12V/6Ω = 2A

Finally

V = 6V and R = 6Ω

I' = 6V/6Ω = 1A

so we see that

2I' = I

I' = I/2

Hence, the current is halved.

Exploring the Kuiper Belt is a common objective for certain space missions. Previous missions like the NASA Pioneers 10 and 11 helped pave the way for future explorations, which now include plans to explore moons like Europa for signs of life.

Explanation:

The planned missions that this question refers to are likely spacecraft designed to explore the outer regions of our solar system, including destinations such as the Kuiper Belt. The primary goal of such missions is often to gather data about the composition, structure, and the variety of objects within the Kuiper Belt. Notable examples of past missions with similar objectives include NASA's Pioneers 10 and 11 which were pioneers in interplanetary space travel, aiming to assess the feasibility of navigating through the asteroid belt beyond Mars and to measure radiation hazards in Jupiter's magnetosphere. They provided essential data that informed the design of future space missions. An upcoming significant mission is the Europa Clipper, which aims to explore Europa, one of Jupiter's moons, to understand its subsurface ocean and the potential for life there.
