The vessels A and B of equal volume and weight are immersed in water to depth h.The vessel A has an opening at the bottom through which water can enter.If the work done in immersing A and B are `W_(A)` and `W_(B)` respectively,then

Two bodies of equal weight and volume and having the same shape, except that one has an opening at the bottom and the other is sealed, are immersed to the same depth in water. Is less work required to immerse one than the other? If so, which one and why?

Two vessels A and B are filled with water at 4^(@)C .Vessel A is heated and vessel B is cooled.Then water overflows in

Consider the two process on a system as shown in figure. The volumes in the initial state and in the final state are the same in the two process A and B. If W_(1) and W_(2) be the work done by the system in the processes A and B respectively then-

Two vessels A and B of equal volume (V_0) are connected by a narrow tube which can be closed by a value. The vessels are fitted with piston which can be moved to change the volumes. Initially, the valve is open and the vessels contain an ideal gas (C_p / C_v = gamma ) at atomspheric pressures (P_0) and atmoshpeheric temperature (T_0) . The walls of the vessels A are diathermic and those of B are adiabatic. The value is now closed and the pistons are slowly pulled out to increase the volumes of the of the vessels to dobuled the original value.(a) Find the temperatures and pressures in the two vessels. (b) The value is now opened for sufficeint time so that the gases acquire a common tempertures and pressures . Find the new values of the temperatuere and the pressures.

A tube of uniform cross section is used to siphon water from a vessel V as shown in the figure. The pressure over the open end of water in the vessel is atmospheric pressure (P_(0)) . The height of the tube above and below the water level in the vessel are h_(1) and h_(2) , respectively. Determine the velocity v_(B) of the water issuing out at B .

Two vessels A and B of different shapes have the same base area and are filled with water up to the same height h (see figure). The force exerted by water on the base is F_(A) for vessel A and F_(B) for vessel B . The respective weights of the water filled in vessels are W_(A) and W_(B) . Then

The height of water in a vessel is h. The vessel wall of width b is at an angle theta to the vertical. The net force exerted by the water on the wall is

Three vessels A, B and C of different shapes contain a water upto the same in the figure P_A, P_B and P_C be the pressure exerted by the water at the bottom of the vessels A, B and C respectively. Then

Three vessels A,B,and C of different shapes contain a water upto the same height as shown in the figure . P_(A) ,P_(B) ,and P_(C) be the pressure exerted by the water at the bottom of the vessels A ,B and C respectively . Then
