Two concentric conducting shells a and b are of radii R and 2R. A charge +q is centred at their center. Shell b is then earthed and a is given charge q. Find the charge on outer surfaces oboth shells.
Ans) THE charge on outer surface of A will be 2q and outer surface of B will be zero due to earthing charge on b will flow to earth.
Write down the condition for the construction of good auditoria. Illustrate the reflection of waves at closed and open ends.
First law of thermodynamics is stand on the principle of the conservation of power. According to the first law, ΔQ = W + ΔU Where, Δ Q = heat given to the system

It is the property of changing readily from a solid or liquid to a vapour. It is the speed that a chemical compounds evaporates. Higher volatility indicates faster evaporation.
Twin paradox: One of the most popular "paradoxes" in history, predicted trhough A. Einstein's special theory of relativity. Take two twins, born on the similar date on Earth.
If a ring were constructed as knid of a space station. How fast must a 50.0-m-radius ring rotate to simulate Earth's gravity?
