Question

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) 1.25 Pa
B) 2.5 Pa
C) 5.0 Pa
D) 7.5 Pa

Answer 1

The pressure exerted by the 7.5 kg block on the tabletop is 122.5 Pa.

Step-by-step explanation:

The pressure exerted by an object is defined as the force applied per unit area. In this case, the force is the weight of the block, which is given as its mass multiplied by the acceleration due to gravity (9.8 m/s²).

By using the formula for pressure (Pressure = Force / Area), we can calculate the pressure exerted by the block on the tabletop.
