Question

What’s answer of example 2

Answer 1

Answer:

200000 pascal

Explanation:

pressure = f/area

f=20000N

a=1000cm²=0.1 m²

thus p= 20000÷0.1

= 200000 pascal

hope it helps :)

Answer 2

Answer:

Force applied by the Elephant on One Foot=20000 N

Force applied by the Elephant on One Foot=1000 cm²=0.1 m²

As Elephants have 4 feet,

Therefore,

The total force applied by the Elephant on the Ground=(20000*4) N=80000

N.

The Total Area of the feet of the Elephant=(0.1*4) m²=0.4 m²

Therefore,

The total pressure applied by the Elephant on the Ground=Force/Area

=(80000/0.4) N/m²=200000 N/m²

This might Help.Thank You:)
