021. The hydrostatic pressure 'P' of a liquid column depends upon the density d', height 'h' of liquid column and also an acceleration 'g' due to
gravity. Using dimensional analysis, the formula for pressure P is
O A. p = hdg
OB. p=h/dg
O c. p=d/hg
O D. p = g/hd

When you drop a pebble from height a it reaches the ground with speed v if there is no air resistance. from what height should you drop it so it will reach the ground with three times the speed? (a) 9m (b) 3m (c) 6m (d) 18m

Distinguish between linear momentum and angular momentum
