Water is flowing in a container at a rate proportional to the square of the amount of water present inside the container.If at t=0 volume of water inside the tank is` V_(0)`& it takes 6 hours for the volume to become` 2V_(0)` then the time (in hours) taken for the volume to become `4V_(0)` is equal to

If a given volume of water in a 220 V heater is boiled in 5 min , then how much time will it take for the same volume of water in a 110 V heater to be boiled?

A ball floats on the surface of water in a container exposed to the atmosphere. Volume V_(1) of its volume is inside the water. The container is now covered and the air is pumped out. Now let V_(2) be the volume immersed in water. Then

Water is pouring into a cubiodal reservoir at the rate of 60 litres per minute. If the volume of reservoir is 108m^3, find the number of hours it will take to fill the reservoir.

An ideal gas is in a container of volume V_0 at pressure P_0 If the same amount of gas is in container of volume 3V_0 at pressure P_0 . then the ratio of final average translational kinetic energy to the initial average translational kinetic energy of the gaseous molecule is

A hollow sphere of volume V is floating on water surface with half immersed in it. What should be the minimum volume of water poured inside the sphere so that the sphere now sinks into the water ?

From a tap of inner radius 0.75cm, water flows at the rate of 7m per second. Find the volume in litres of water delivered by the pipe in one hour.

From a tap of inner radius 0.75cm, water flows at the rate of 7m per second. Find the volume in litres of water delivered by the pipe in one hour.

Oridinary water contain one part of heavy water per 6000 parts of water by weight. The number of heavy water molecules present in a drop of water of volume 0.01 mL is (density of water 1 g/mL)

Water is being poured into a tank at the rate of approximately 4 cubic feet per hour. If the tank is 6 feet long, 4 feet wide, and 8 feet deep, how many hours will it take to fill up the tank ?

A tank of height H and base area A is half filled with water and there is a small orifice at the bottom and there is a heavy solid cylinder having base area (A)/(3) and height of the cylinder is same as that of the tak. The water is flowing out of the orifice. Here cylinder is put into the tank to increase the speed of water flowing out. After long time, when the height of water inside the tank again becomes equal to (H)/(2) , the solid cylinder is taken out. then the velocity of liquid flowing out of the orifice (just after removing the cylinder) will be
