An elephant weighs 600 kg. The contact area between the foot and the ground is 600 square centimeters. How much pressure does the elephant exert on the ground when it stands on the ground with four feet? How much pressure does the elephant put on the ground when raising its feet
600 sq cm = 0.06 sq m
Pressure = 600 × 10 ^ (0.06 × 4) = 25000pa
After lifting foot = 25000 × 2 = 50000pa
