An L-shaped glass tube is just immersed in flowing water such that its opening is pointing against flowing water. If the speed of water current is `v`, then

An L-shaped glass tube is immersed in a flowing liquid such that its opening is pointing against the currents. If the speed of flow is v Study following statement: (i) the liquid in the tube rises to a level A (ii) The liquid in the tube rises to the level B (iii) The liquid in the tube rises to the level C (iv) The magnitude of h is (v^2)/(2g) Choose the correct statement (s)

Correct flow of water current in sponges is
