With the increase in the area of contact of an object the pressure

The resultant of two opposite parallel forces $$12\ N$$ and $$7\ N$$ is _____ N

Which of the following is a correct statement regarding the pressure due to fluids?

In the superhit film 'Raja Hindustani', Amir Khan greets his beloved by shaking hand. What kind of force do they exert?

The two femurs each of the cross-sectional area 10 cm$$^2$$ support the upper part of a human body of mass 40 kg. The average pressure sustained by the femurs is then (Takes g= 10 m s$$^{-2}$$)

Atmospheric pressure exerted on earth is due to the.

A 50 kg girl wearing heel shoes balances on a single heel. The heel is circular with a diameter 1 cm. The pressure exerted by the heel on the horizontal floor is then (Take g = 10 m s$$^{-2}$$)

A force acts for 10s on a body of mass  $${10^{ - 2}}{\text{kg}}$$ initially at rest. Then after the force ceases to act. The body traverses 0.5m in next 5s. The magnitude of the force is 

Force acts on an object may change
