What pressure is exerted on the ground by on elephant weighing 40 000 N stands on one food of area 10 m2?
The pressure exerted by the elephant on the ground can be calculated using the formula:
Pressure = Force/Area
In this case, the force (weight of the elephant) is 40,000 N and the area is 10 m^2.
Pressure = 40,000 N / 10 m^2
Pressure = 4,000 N/m^2
Therefore, the pressure exerted on the ground by the elephant is 4,000 N/m^2.
