Question

a flashlight uses the chemical energy stored in a battery. this chemical energy is eventually converted into which two forms of energy?
○ mechanical and nuclear
○ radiant and thermal
○ thermal and mechanical
○ nuclear and electrical

Explanation:

A flashlight's battery chemical energy is converted to electrical energy first, then the bulb produces radiant (light) energy and thermal (heat) energy. Mechanical energy (movement) and nuclear energy (atomic reactions) are not involved here. So the correct pair is radiant and thermal.

Answer:

B. radiant and thermal
