Ответ:
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.
