The atmospheric pressure above a swimming pool changes from 755 to 765mm of mercury.The bottom of the speed is a 12m x 24m rectangle.By how much does the force on the bottom of the pool increase?
What does "the bottom of the speed" mean?
Muliply the pool bottom area by the pressure change, which is
(10/760)*Po = 1333 N/m^2
The pool area is 12*24 = 288 m^2
