Solar-powered cars use energy from the Sun to work. A panel on the car absorbs light energy from the Sun, which then generates an electric current. This electric current, in turn, allows the car to move. Which shows the correct order of energy transformations that take place in a solar-powered car?

A
electrical, chemical, kinetic
B
electrical, kinetic, radiant
C
radiant, chemical, electrical
D
radiant, electrical, mechanical
94

The diagram shows a swinging pendulum.

Question illustration
A
The pendulum will slow down and eventually stop moving as the mechanical energy transforms to thermal energy.
B
The pendulum will slow down and eventually stop moving as the mechanical energy disappears.
C
The pendulum will continue moving at the same speed because mechanical energy is created as the pendulum moves.
D
The pendulum will slow down but will not stop moving because some of the mechanical energy is destroyed.
