1.	A matallic block weighs `15N` in air. It weights `12N` when immersed in water and `13 N` when immersed in another liquid. What is the specific gravity of the liquid?A. `1//3`B. `2//3`C. `12//13`D. `13//15`
Answer» Correct Answer - B `(sigma)/(rho_w) = (15)/(15-12) , (sigma)/(rho_1) = (15)/(15-13)` `implies (rho_l)/(rho_w) = 2/3`.

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)`
