Answer 1

A 7.5 kg block is placed on a table. If its bottom surface area is 0.6 m2, how much pressure does the block exert on the tabletop?

A. 367.5 Pa

B. 122.5 Pa

C. 73.5 Pa

D. 226.5 Pa

Answer 2

pressure is force per area. Weight is force, given in Newtons and is given by F=mg
F=7.5 * 9.81 = 73.575N
Pressure = 73.575N/0.6m² = 122.5 Pa
