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.
If air is blown under one of the pans of a phusical balance in equilbrium, then the pan willA. not be disturbedB. go upC. go downD. becomes vertical
The pans of a physical balance are in equilibrium. Air is blown under the right hand pan, then the right hand pan willA. Move upB. Move downC. Move erraticallyD. Remain at the same level
A ship made of iron can float in water but an iron needle sinks. Why ?
Small droplets of liquid are usually more spherical in shape than larger drops of the same liquid becauseA. Force of surface tension is equal and opposite to the force of gravityB. force of surface tension predominates the force of gravityC. force of gravity predominates the force of surface tensionD. force of gravity and force of surface tension act in the same direction and are equal
Two capillaries made of same material but of different radii are dipped in a liquid. The rise of liquid in one capillary is 2.2 cm and that in the other is 6.6 cm . The ratio of their radii isA. `9:1`B. `1:9`C. `3:1`D. `1:3`
A necklace weighs `50 g` in air, but it weighs `46 g` in water. Assume that copper is mixed with gold to prepare the necklace. Find how much copper is present in it. (Specific gravity of gold is `20` and that of copper is `10`.)A. 10gB. 20gC. 30gD. None
Velocity of water in a river isA. Same everywhereB. More in the middle and less near its banksC. Less in the middle and more near its banksD. Increase from one bank to other bank
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)`
