Length of horizontal arm of a uniform cross section U-tube is l = 21 cm and ends of both of the vertical arms are open to surrounding of pressure 10 x 500 N/m^2. A liquid of density ρ = 10^3 kg/m^3 is poured into the tube such that liquid just fills the horizontal part of the tube. Now one of the open ends is sealed and the tube is then rotated about a vertical axis passing through the other vertical arm With angular velocity ω0=10rad/s. If length of each vertical arm is a = 6 cm, calculate the length of air column in the sealed arm. (in cm)

A solid cylinder of height h and mass m is floating in a liquid of density ρ as shown in the figure. Find the acceleration of the vessel (in m/s^2) containing liquid for which the relative downward acceleration of the completely immersed cylinder w.r.t. vessel becomes equal to one-third of that of the vessel. (Take g = 10 m/s^2)

A vessel with a symmetrical hole in its bottom is Paste on a cart. The mass of the vessel and the cart is 1.5 kg. With what force F (in ×10^2 N) should the cart be pulled that the maximum amount of water remains in the vessel. The dimensions of the vessel are as shown in the figure. Given that b = 50 cm, c = 10 cm, area of base `A= 40 cm^(2), L = 20 cm, g = 10 m//s^(2).

A ball of density rho is dropped on to a horizontal solid surface. It bounces elastically from the surface and returns to its original position in a time t1. Next, the ball is released from the same height but this time it strikes the surface of a liquid of density rhoL ( > rho but less than 2rho ), and takes t2 second to come back to its original height
