2. Heat travels through vacuum by
- A. conduction.
- B. convection.
- C. radiation.
- D. convection and radiation.
Answer: C. radiation.
Conduction → heat transfer in solid
Convection → heat transfer in fluid
Radiation → heat transfer through vacuum
Conduction → heat transfer in solid
Convection → heat transfer in fluid
Radiation → heat transfer through vacuum
3. A mirror is used to direct sunlight onto the wall of a classroom by
- A. dispersion.
- B. refraction.
- C. reflection.
- D. radiation.
Answer: C. reflection.
When a ray of light approaches a smooth polished surface and the light ray bounces back, it is called the reflection of light. The incident light ray that land on the surface is reflected off the surface. The ray that bounces back is called the reflected ray.

4. Which of the following energy changes takes place in ringing bell?
- A. Potential to kinetic
- B. Potential to sound
- C. Mechanical to sound
- D. Sound to light
Answer: C. Mechanical to sound
The mechanical energy is used to vibrate the metallic body of the ring-bell. When the bell vibrates, it produces sound energy.

5. A fuse is connected in an electric circuit to
- A. prevent electric shock.
- B. increase the current.
- C. prevent current from increasing.
- D. increase the heat generated.
Answer: C. prevent current from increasing.
A fuse is an electrical safety device that operates to provide overcurrent protection of an electrical circuit. It is designed to melt and separate in the event of excessive current thereby stopping or interrupting the current.
