A balloon is in the form of right circular cylinder of radius 1.5m and length 4m and is surmounted by hemispherical ends. If the radius is increased by 0.01m and the length by 0.05m, the percentage change in the volume of the balloon is

The length of a body is measured as 3.51m, if the acuracy is 0.01 m, then the percentage errof in the measurement is

A silver cylindrical rod has a length of 0.5 m and radius of 0.4 m, find the density of the rod, if its mass is 2640 kg.

A rope ladder of length L is attached to a balloon of mass M. As the man of mass m climbs the ladder into the balloon basket, the balloon comes down by a vertical distance s. Then the increase in potential energy of man divided by the increase in potential energy of balloon is
