Water enters through end A with a speed `v_1` and leaves through end B with a speed `v_2` of cylindrical tube AB. The tube is always completely filled with water. In case I the tube is horizontal, in case II it vertical with the end A upward and in case III it is vertical with the end B upward. We have `v_1=v_2`forA. Case IB. Case IIC. Case IIID. Each case

Water enters through end A with a speed `v_1` and leaves through end B

1.	Water enters through end A with a speed `v_1` and leaves through end B with a speed `v_2` of cylindrical tube AB. The tube is always completely filled with water. In case I the tube is horizontal, in case II it vertical with the end A upward and in case III it is vertical with the end B upward. We have `v_1=v_2`forA. Case IB. Case IIC. Case IIID. Each case
Answer» Correct Answer - D This happens in accordance with equation of continuity and this equation was derived on the principal of conservation of mass and it is true in every case, either tube remain horizontal or vertical.

Figure shows a cubical block of side 10 cm and relative density 1.5 suspended by a wire of cross sectional area `10^(-6) m^(2)`. The breaking stress of the wire is `7 xx 10^(6) N//m^(2)`. The block is placed in a beaker of base area `200 cm^(2)` and initially i.e. at t = 0, the top surface of water & the block coincide. There is a pump at the bottom corner which ejects `2 cm^(3)` of water per sec. Find the time at which the wire will break.

A large tank is filled with water to a height `H`. A small hole is made at the base of the tank. It takes `T_(1)` time to decrease the height of water to `(H)/(eta) (eta gt 1)`, and it takes `T_(2)` times to take out the rest of water. If `T_(1) = T_(2)`, then the value of `eta` isA. 2B. 3C. 4D. `2 sqrt(2)`
