1.	A wide cylindrical tank with a small opening in the bottom has a water column of height `h_(1)` and above the water column, there is a layer of kerosene oil of thickness `h_(2). The velocity of efflux through the opening isA. `sqrt(2gh_(1))`B. `sqrt(2gh_(2))`C. `sqrt(2g(h_(1)+h_(2)))`D. Data is not sufficient.
Answer» Correct Answer - C The velocity of efflux does not depend on the density of liquid.

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.
