Question

(1) A force of 1200 N acts on the surface of area 10 cm² normally. What would be the pressure on the surface?
(2) The elephant weighs 20,000 N stands on one foot of area 1000 cm². How much pressure would it exert on the ground?

Answer 1

Answer:

120*(10^4)N (1200000 N)

Explanation:

(1) Pressure = Force / Area

Force=1200N

Area = 10 cm² = 10*(10^-2)²=10*(10^-4) m²

Pressure=(1200/10)*(10^4)=120*(10^4)N

Hope this answer helped you
