Stressful life events or trauma — such as the death or illness of a loved one, divorce, or a job loss — also may lead to insomnia.
The average kinetic energy of an atom in helium gas at temperature T is given by,
K.E=
here, K is botzmann constant =1.38×10⁻²³ m² kg s⁻² K⁻¹
Given, K.E= 6.21×10⁻²¹ J
Substituting the values,

T= 300 K
Therefore, at temperature 300 K the average kinetic energy of the atom in helium gas is 6.21×10⁻²¹ J.
Answer:
The heavy body
Explanation:
The heavy body because it's heavier and the heavier something is the more kinetic energy it has.
Pretty sure this is correct
