1.	A block of iron is kept at the bottom of a bucket full of water at `2^@C`. The water exerts bouyant force on the block. If the temperature of water is increased by `1^@C` the temperature of iron block also increases by `1^@C`. The bouyant force on the block by waterA. will increaseB. will decreaseC. will not changeD. may decrease or increase depending on the values of their coefficient of expansion
Answer» Correct Answer - A Increasing the temperature of water from `2^(0)C` to `3^(0)C` increases its density while decreases the density of iron. Hence the bouyant force increases.

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.
