Explain what happens when a rock falls from a height.
- A.
Potential energy turns to mechanical energy
- B.
Mechanical energy turns to potential energy
- C.
Potential energy turns to kinetic energy
- D.
Kinetic energy turns to potential energy
- E.
Kinetic energy turns to mechanical energy
Correct Answer
C. Potential energy turns to kinetic energyExplanation
When a rock falls from a height, its potential energy is converted into kinetic energy. Potential energy is the energy an object possesses due to its position or condition, in this case, the rock's height. As the rock falls, it gains speed and its potential energy decreases while its kinetic energy increases. Kinetic energy is the energy of motion, so as the rock falls, its potential energy is transformed into the energy of its movement. Therefore, the correct answer is that potential energy turns to kinetic energy.Rate this question:

Sound travels in ________________.
- A.
Transverse waves
- B.
Longitudinal waves
- C.
Pure energy waves
- D.
Big waves
- E.
Hertz waves
Correct Answer
B. Longitudinal wavesExplanation
Sound travels in longitudinal waves, which are characterized by the vibration of particles in the same direction as the wave propagation. In a longitudinal wave, the particles of the medium move back and forth parallel to the direction of energy transfer. This type of wave is responsible for the compression and rarefaction of the medium, creating areas of high and low pressure. Therefore, the correct answer is longitudinal waves.Rate this question:

- A.
visible light
- B.
Sound
- C.
Radio waves
- D.

- E.
The waves at baseball games.
Correct Answer
B. SoundExplanation
Sound is a mechanical wave because it requires matter to travel through. Unlike visible light or radio waves, which can travel through empty space, sound waves need a medium, such as air, water, or solids, to propagate. This is because sound waves are created by the vibration of particles in the medium, causing them to transfer energy to neighboring particles and propagate the wave. Therefore, sound waves cannot travel in a vacuum or empty space.Rate this question:

This is the inside of a fiber-optic cable it shows 2 light sources traveling through the cable. what is happening over and over on the inside of the cable as the light passes through?
- A.
The light is going out the sides
- B.
The light is refracting off the sides
- C.
The light is reflecting off the sides
- D.
The light is not touching the fiber-optic cable
- E.
The light is getting brighter
Correct Answer
C. The light is reflecting off the sidesExplanation
As the light passes through the fiber-optic cable, it repeatedly reflects off the sides of the cable. This phenomenon is known as total internal reflection. It occurs because the cable is designed to have a higher refractive index than the surrounding medium, causing the light to bounce back and forth within the cable rather than escaping out the sides. This reflection allows the light to travel long distances without significant loss of signal strength.Rate this question:

- A.
Electromagnetic waves
- B.
Mechanical waves
- C.
Light waves
- D.
People waves
- E.
Super waves
Correct Answer
B. Mechanical wavesExplanation
Energy can travel through solid and liquids via mechanical waves. Mechanical waves are waves that require a medium, such as a solid or liquid, to propagate. These waves transfer energy by causing particles in the medium to vibrate or oscillate. Examples of mechanical waves include sound waves, which can travel through solids, liquids, and gases, and water waves, which can travel through liquids. Electromagnetic waves, on the other hand, do not require a medium and can travel through a vacuum, while light waves are a type of electromagnetic wave. "People waves" and "super waves" are not recognized scientific terms and do not accurately describe how energy can travel through solid and liquids.Rate this question:

This is the measure of the intensity of a vibration.
Correct Answer
volumeExplanation
Volume is a measure of the intensity of a vibration. In the context of sound, volume refers to the loudness or softness of a sound. It is determined by the amplitude or strength of the sound wave. A higher volume indicates a stronger vibration and a louder sound, while a lower volume indicates a weaker vibration and a softer sound. Therefore, volume is a suitable measure for the intensity of a vibration.Rate this question:
