When atmospheric pressure increases, what happens to the absolute pressure at the bottom of a pool?
a. it increases by a greater amount.
b. it increases by a lesser amount.
c. it does not change.
d. it increases by the same amount.
e. it depends on the depth of the pool.

D. It increases by the same amount.

Explanation:

We know that

Relationship between Absolute pressure ,Atmospheric pressure and gauge pressure given as

Absolute pressure = Atmospheric pressure + gauge pressure

P(abs) = P(atm) + P(gauge)

So when Atmospheric pressure  increases then Absolute pressure will also

increases by same amount because absolute pressure is the sum of gauge and atmospheric pressure.

D. It increases by the same amount.

wavelength divides in half and speed stays the same.
