A0.095-kg aluminium sphere is dropped from the roof of a 55-m-high building. the specific heat of aluminium is 900 j/kg⋅c∘ .
if 65 % of the thermal energy produced when it hits the ground is absorbed by the sphere, what is its temperature increase?

Increase in temperature will be

Explanation:

We have given mass of the aluminium m = 0.095 kg

Height h = 55 m

Specific heat of aluminium c = 900 J/kg°C

We know that potential energy is given as

Now 65 % of potential energy

Now this energy is used to increase the temperature

So

report!

explanation:

physics means: "the branch of science concerned with the nature and properties of matter and energy. the subject matter of physics, distinguished from that of chemistry and biology, includes mechanics, heat, light and other radiation, sound, electricity, magnetism, and the structure of atoms."
