Carla pushes a toy car and lets it go. The toy car rolls and gradually comes to a stop. What would make the car stop?A. A force must be applied to the car in the direction opposite to that in which it is moving.
B. A force must be applied pushing the car forward in the same direction as the moving car.
C. A force must be applied in a direction pushing the car upward to make the car stop.
D. A force must be applied in a direction pulling the car downward causing the car to stop.

Answers

A is correct :) If you push up or down on a toy car it won't nessicarily stop. If you push it in the same direction, it will probably go faster. If you push it in the opposite direction, it will stop. (Or go backwards depending on how hard you push)
A is correct because this creates friction so the car stops.

What are 4 things that can happen to a light wave when it hits an object?

Answers

Explanation:

The four things that can happen to a light wave when it hits an objects are :

1. Reflection : The bouncing back of light when the light wave strikes on a surface is called reflection of light.

2. Refraction : The bending of light when the light wave moves from one medium to another.

3. Absorption : Absorption is the process in which the light wave do not reflect back. It stays inside the material.

4. Transmission : Transmission of light is the process in which light wave goes continuously straight.

Some other process that are shown by a light wave are polarization, scattering etc.

Final answer:

When a light wave hits an object, it can undergo reflection, transmission, absorption, or scattering.

Explanation:

When a light wave hits an object, several things can happen:

  1. Reflection: The light wave can bounce off the object, changing its direction but maintaining its frequency and speed.
  2. Transmission: The light wave can pass through the object, with some of the wave being absorbed and some being transmitted.
  3. Absorption: The light wave can be absorbed by the object, converting its energy into heat.
  4. Scattering: The light wave can be scattered in different directions by the object, leading to a change in the overall direction of the wave.

When it is cloudy, many of the sun’s rays never reach the Earth. What does this do to the temperature

Answers

Answer:

When it is cloudy, many of the sun’s rays never reach the Earth. It leads to cooler temperatures.

Explanation:

During the day, the sun warms the earth. When the sky is clear, more heat reaches the earth's surface . This leads to warmer temperatures.

However, when the sky is cloudy, a few drops of clouds reflect some of the sun's rays. As a result, less solar energy can reach Earth's surface, causing Earth to heat up more slowly. This leads to cooler temperatures.

If cloudy skies are forecast when forecasting daytime temperatures, expect lower temperatures than you would expect if clear skies were forecast.

Similarly, cloud cover at night has the opposite effect. When the sky is clear, the heat emitted from the earth's surface freely escapes into space, resulting in cooler temperatures.

However, when there are clouds, some of the heat from the earth's surface is captured by the clouds and returned to the earth. As a result, temperatures drop more slowly than when the sky is clear.

A basketball with a mass of 0.80 kg is accelerated with a force of 16.0 N. If resisting forces are ignored, what is the acceleration of the basketball to the nearest m/s2?

Answers

Answer:

Acceleration = 20 m/s2

Further explanation:

16 N = 0.80 kg x acceleration

Acceleration = 20 m/s2
Force (F) = mass (M) x acceleration (a)
F= 16.0 N
M= 0.80kg
a= ??

16.0 = 0.80 x a
___ ______
0.80 0.80

a= 20 m/s^2
