Answer:
decreases
Explanation:
The angular frequency of the mass is given by

where, k is the spring constant and m be the mass of the body which is doing oscillations.
if the mass of the body increases, so the value of angular frequency decreases, as the angular frequency is inversely proportional to the square root of the mass of the body.

Answer:
Because most of the human body (about 70% of it) consists of water
Explanation:
The main reason why the specific heat capacity of the human body is very close to that of water is that water makes approximately 70% of the substances of which the human body consists. However, the human body has a slightly smaller specific heat capacity than water, because it contains also other elements/substances, and since water is one of the substances with the higher specific heat capacity at all, the specific heat capacity of the body is a bit smaller.
