Question

a professor of height 1.8 m and 0.75 m width has a mass of 85kg and layson a densely packed bed of nails, how much pressure does the professor feelfrom the nails? Assume the professor is rectangle.a) 330 atm

Answer 1

Answer:

617 pascal

Explanation:

Height of professor, h = 1.8 m

width of professor, w = 0.75 m

mass, m = 85 kg

Area of professor, A = height x width

A = 1.8 x 0.75 = 1.35 m²

Force, F = mg = 85 x 9.8 = 833 N

Pressure = Force / Area

P = 833 / 1.35

P = 617 Pascal

Thus, the pressure feel by the professor is 617 Pascal.
