A body travels 200cm in the first two seconds and 220cm in the next four seconds. What will be the velocity at the end of the seventh second from start?
2)
Define gravitational potential energy. Derive an expression for it at a point in the gravitational field of mass
3)
Obtain by the method of dimensional analysis an expression for the surface tension of a liquid rising in a capillary tube. Assume that the surface tension (force per unit length) depends on the mass m, pressure p of the liquid and radius r of a capillary tube. The constant K=1/2
