A brick weighs 50.0 N,and measures 30.0 cm × 10.0 cm × 4.00 cm.What is the maximum pressure it can exert on a horizontal surface due to its weight?

Question

Quizplus · Accepted Answer

The maximum pressure the brick can exert on a surface is when it is placed on its smallest surface area, which is 10.0 cm x 4.0 cm = 40.0 cm^2.

To calculate the pressure exerted by the weight of the brick, we divide the weight by the area:

Pressure = weight / area
Pressure = 50.0 N / 0.0040 m^2
Pressure = 12,500 Pa = 12.5 kPa

Therefore, the correct answer is D) 12.5 kPa.
