A spherical ball is moving with terminal velocity inside a liquid determine the relationship of rate of heat loss with the radius of ball.

A spherical ball falls through viscous medium with terminal velocity v . If this ball is replaced by another ball of the same mass but half the radius, then the terminal velocity will be (neglect the effect of buoyancy.)

If a spherical steel ball is melted to make 8 new identical balls then the radius of new ball is how many times the radius of the original ball?

A solid spherical ball of iron with radius 6 cm is melted and recase tin to three solid spherical balls . The radii of the two of the balls are 3 cm and 4 cm respectively determine the diameter of the third ball.
