There are two cylinder shaped wooden bullets, each having mass M, in a vertical wall sewage, which contains water in it. The two bullets have same size and same material , they touch each other and walls of sewage. One of them is totally under water, where the other one is immersed only half into water. Friction is negligible if density of wood is given by (3)/(x)p_(omega) (p_(omega) "is density of water") then find x

There are two wires. One of them carries a current . How will you find out which one carries a current ?

Two identical solid balls, one of ivory and the other of wet-clay are dropped from the same height on the floor. Which one will rise to a greater height after striking the floor and why?

Two identical bodies are made of a material for which the heat capacity increases with temperature. One of these is at 100^@ C, while the other one is at 0^@ C. If the two bodies are brought into contact, then assuming no heat loss the final common temperature is _____

Two different non-parallel lines meet the circle abs(z)=r . One of them at points a and b and the other which is tangent to the circle at c. Show that the point of intersection of two lines is (2c^(-1)-a^(-1)-b^(-1))/(c^(-2)-a^(-1)b^(-1)) .
