Question 1
Assume that the atmospheric pressure today is exactly 1.00 atm. What is the pressure at point A, located h = 9 m under the surface of a lake, in atmospheres? 1.87
Question 2
How much will the pressure increase if we go further down to point B, which is 1.50 m below point A, in atmospheres? (Note that we are not asking for the pressure at B.)
