Which object has the most thermal energy? A. A 6 kg rock at 15°C
B. A 6 kg rock at 10°C
C. A 10 kg rock at 10°C
D. A 10 kg rock at 15°C

D. A 10 kg rock at 15°C

Explanation:

Thermal energy is heat energy, meaning that the hotter rocks will have more energy.

The heavier/larger rocks can store more energy.

So if we combine the largest two variables, we get a 10kg rock at 15°C.

a) electrical > light, sound, and thermal< < < <

) the mechanical energy of the firefighter moving.< < < < a) electrical > light, sound, and thermal< < < <

c) both a and b.

b. lifting dumbbell weight at 20-degree angle from the body after a 45-degree angle
