A rectangular tank of depth 8 meter is full of water `(mu=4//3)`, the bottom is seen at the depth

A rectangular tank 8m deep is full of water. By how much does the bottom appear to be raised if the refractive index of water is 4//3 ?

A rectangular tank of length 10m, breadth 5m and depth 6m is full of water. How much water does it contain?

Water flows from the base of rectangular tank of depth 16 mater. The rate of flowing the water is proportional to the square root of depth at any time t. If depth is 4 mater when t=2 hours then after 3 hours the depth is
