Answer:
The specific heat of a substance (per unit of mass) has dimension L. T. Θ−1, or (L/T)2/Θ. Therefore, the SI unit J/K/kg is equivalent to metre squared per second squared per kelvin (m2 K−1 s−2).
As the molecules at the surface of a liquid absorb heat, they begin to move around more quickly. This gives them the energy to break the bonds that connect them to other water molecules. When the molecules are moving fast enough, they are able to "escape." They leave the surface of the liquid as gas molecules.
Answer:
To avoid slipping while playing badminton or to increase friction between the shoes and the badminton court or to enhance the grip.
Explanation:
As the question is general so I will try answer it generally.
As badminton court is usually slippery and flat with no or very little friction and while playing badminton, players have to move very fast from place to place.
So, in order to effectively move faster to take the difficult shots with accuracy badminton players increase the friction between their shoes and the badminton court by shuffling resin to their shoes. It helps to enhance the grip.
Answer:
the spring constant k = 
the value for the damping constant 
Explanation:
From Hooke's Law
Thus; the spring constant k =
The amplitude is decreasing 37% during one period of the motion
Therefore; the value for the damping constant
