which of the following are examples of either heat or light energy? select all that apply. a bicycle wheel sun stereo speakers a lightbulb a campfire
Answer
Explanation:
Step1: Analyze a bicycle wheel
A bicycle wheel has kinetic energy when in motion and potential energy when stationary. It is not an example of heat or light energy.
Step2: Analyze the Sun
The Sun emits both heat and light energy. It is a major source of both forms of energy for Earth.
Step3: Analyze stereo speakers
Stereo speakers convert electrical energy into sound energy. They do not produce heat or light energy as their main - functioned output.
Step4: Analyze a lightbulb
A lightbulb converts electrical energy into light energy (and some heat energy as a by - product). It is an example of light energy.
Step5: Analyze a campfire
A campfire produces both heat and light energy. It is a source of both forms of energy.
Answer:
B. Sun, D. a lightbulb, E. a campfire
