1.	A soap bubble is blown with the help of mechanical pump at the mouth of a tube. The pump produces a cartain increase per minute in the volume of the bubble, irrespective of its internal pressure. The graph between the pressure inside the soap bubble and time `t` will beA. B. C. D.
Answer» Correct Answer - A `Deltap=(4T)/(r ) implies Deltap prop (1)/(r )` As radius of soap bubble increases with time. `therefore " " Delta p prop(1)/(t)`

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)`
