3

The sun emits electromagnetic waves at many frequencies, but mostly in the infrared, visible, and ultraviolet spectrums. What kind of energy is this?

A
nuclear
B
radiant
C
thermal
D
chemical
4

When Anna eats an apple, the sugars in that apple are broken down into the substance called glucose. Glucose is then burned in her body for energy. One of the body parts that needs this energy is the heart, which beats due to electrical impulses. A byproduct of this glucose breakdown is the heat that warms her body and is later released.

A
Mechanical energy is converted to kinetic energy, which is then converted to potential energy.
B
Chemical energy is converted to thermal energy and electrical energy.
C
Electrical energy is converted to chemical energy and thermal energy.
D
Mechanical energy is converted to potential energy which is then converted to kinetic energy.
5
