(a) What is a geostationary satellite? (b) Name two types of Lasers.

A 50 N force is applied to the free end of a spiral spring of force constant, 100 N m\(^{-1}\). Calculate the work done by the force to stretch the spring.

The effective potential energy, E, of a lunar satellite of mass, m, moving in an. elliptical orbit around the moon of mass, m, is given byE = \(\frac{K^{2}}{2m_{1}r^{2}} - \frac{Gm_{1}m_{2}}{r}\) where r is the distance of the satellite from the mooń and G is the universal gravitational constant of dimensions, M\(^{-1}\)L\(^{3}\)T\(^{2}\).Ďetermine the dimensions of the angular momentum, K, of the satellite using dimensional analysis.

State three properties of a semiconductor.
