When the pressure on a sphere is increased by 80 atmospheres, then its volumes decreases by 0.01%. Find the bulk modulus of elasticity of the material of sphere.

Find the radius of the sphere, if the rates of increase in its volume and surface area are equal.

The radius of sphere is measured with an error of 2% what will be the error in its volume ?

At a certain instant the volume of a sphere increses at the rate of 36 cm^3//sec and its surface area increases at the rate of 12 cm^2//sec . find the rate of change of its radius at that instant.

Compute the bulk -modulus of water from the following data: Initial volume = 100.0 litre, Pressure increase = 100.0 atm (1 atm = 1.013 xx 10^5 Pa) , Final volume = 100.5 litre. Compare the bulk modulus of water with that of air (at constant temperature). Explain in simple terms why the ratio is so large.

The radius of a sphere at 0^@C is 100 cm. when temperature increases the radius becomes 101 cm. Calculate the volume expnassion of the sphere.

The side of a square is increasing at the rate of 0.01 cm per sec. Find the rate of change of its area at the instant when each side is 4 cms.

A spherical .ball.contracts in volume by 0.01% when subjected to a normal uniform pressure of two atmospheres. What is the bulk modulus of its material in C.G.S units?
