1. A simple pendulum consists of a light inextensible string AB with length L, with the end A fixed, and a perticle of mass M attatched to B. The pendulum oscillates with period T. It is suggested that T is proportional to the product of powers of M, L and g. Use dimensional analysis to find this relationship. 2. T = K (l/g)1/2 3. ?? Dont know where to start on this one. some sort of substitution to find the variables, but i dont know how.
