Two thin evacuated (one end closed) glass take A and B are carefully immersed in a beaker containing Mercury such a way that there is no chance to get air into the tubes. A is stand vertically and B is making an angle `theta` with the vertical.Is any height difference of Mercury levels in tube A and B? Justify your answer.

A child dipped two identical capillary tubes,one in a beaker containing mercury.He observed that water and mercury have risen through the tubes to a certain heights. What difference did he observe in the shape of the meniscus of the two liquids in the tube?

When a body is projected into air with certain initial velocity making an angle with the horizontal,it will travel in a parabolic path. a)What are the vertical and horizontal components of velocity? b)With a diagram derive an expression for: (i)maximum height (ii) time of flight. c)A ball is dropped through the window of a train travelling with high velocity,to a man standing near the track.The ball _________ (i)falls down vertically. (ii)moves straight horizontally. (iii)follows an elliptical path. (iv)follows a parabolic path.
