A small drop of water of surface tension ∂ is squeezed between two clean glass plates so that a thin layer of thickness d and area a is formed between them. If the angle of contact is zero , the force required to pull the p ...

A metal cylinder of 5kg is heated electrically by a 20W heater in a room temp. of 20c. The cylinder temp rises and finally becomes constant at 45C. Assuming rate of heat loss is proportional to the excess temp over surroundin ...

One end of a carpet is nailed to an inclined wedge. Carpet starts to open by rolling purely on the inclined plane. As the time passes potential energy decreases and increase in kinetic energy results. Where does this energy g ...

a rod of length l,mass m is hinged at origin and is slightly tilted at angle θ as shown *Image* we expect it to rotate in the clock wise direction but the torque about the orgin due two both halves is same in magnitude =mglc ...

I have done in rotation a Problem where we put a rotating Disc on horizontal rough platform, find the Average Torque and then solve the equation. Even the ring one is also easier. But How do I do it when there is a square sin ...
