Answer:
Gravitational Potential Energy
Explanation:
a ball is held rest at the top of hill
gravitational potential energy will store due to its height
it. and body will start move downward and its potential energy will convert into kinetic energy due to motion of body
at the ground level it will stop and potential energy will became zero and kinetic energy get convert into internal energy due to collisions
Answer ) Sound level equation
The intensity of a sound wave is related to its amplitude squared by the following relationship: I=(Δp)22ρvw I = ( Δ p ) 2 2 ρ v w . Here Δp is the pressure variation or pressure amplitude (half the difference between the maximum and minimum pressure in the sound wave) in units of pascals (Pa) or N/m2.
Change in thermal energy not always cause it's temperature change. It is the situation when water reaches either at 0 C or 100 C then thermal energy doesn't cause change in temperature instead it changes the state of matter.
In short, Your Answer would be "True"
Hope this helps!
