A7.5 kg block is placed on a table. if it's bottom surface area is 0.6m2, how much pressure does the block exert on the tabletop?
a. 376.5 pa
b. 73.5 pa
c. 226.5 pa
d. 122.5 pa

Pressure is defined as the force per unit area. This measurement is more convenient to use for describing a force exerted. The standard unit for pressure is Pascal. For this problem, force is the gravitational pull from the block. Calculations are as follows:

P = F/A where F = mg

F = 7.5 ( 9.81) = 73.6 N

P = 73.6 N / 0.6 m^2 = 122.5 Pa

Thus, the answer is D.

Ithink the answers is b i hope it my friend message me if i’m wrong and i’ll change my answer and fix it for you
