Given the following information about two spherical tanks that are connected,calculate the work required to fill both tanks from the ground.The first tank: Radius = 1mThe second tank: Radius = 0.5mThe first tank is on the ground and the second tank is 2m above the top of the first tank. The tanks are connected by a tube that is of negligible width. The tube goes through the top of the first tank and the bottom of the second tank. If p > 0 is the density (in kg/m^3) of the liquid in both tanks, calculate the work required to deliver the liquid to fill both tanks from the ground.
