Answer:
Food, wind, water.
Explanation:
This is supposed to be a personalized question so I answered with things that can make/give energy.
Answer:
there is less mass to move so the 2kg ball will move faster. the kinetic energy of the 5kg ball will move slower due to the fact that it needs more energy to move if it has more mass.
So.......
here,
Mass (m) = 20g
Change in Temperature (ΔT) = 29C-10C
= 19C
Specific Heat Capacity = 0.1 cal/ g C
now, plug the info. into the formula,
specific heat capacity = quantity of heat / (mass * change in temperature)
0.1 = quantity of heat / (20 * 19)
0.1 = quantiy of heat / 380
0.1 * 380 = quantity of heat
38 = quantity of heat
so the granite rock boulder absorbed 38 calories of heat energy from the sun
