Question

If pressure exerted on earth is 1 atmospheric pressure. calculate force acting on one
square meter?
Deccribe conservation of energy principle?​

Answer 1

Force acting on 1 square meter will be 1 N.

• Atmospheric pressure is the pressure exerted by the weight of the atmosphere. The S.I unit of atmospheric pressure is N/m². it is the force exerted on a surface by the air above it due to gravitational pull.

Therefore if the Pressure exerted on earth is 1 atmospheric pressure then the force acting on one square meter will be 1 N.

• The law of Conservation of Energy states that energy cannot be created or destroyed - it can only be transferred from one type to another.
