EXERCISE 1) Show on the basis of dimensional analysis that the following relations are
correct:
a. p = 3g/4G where p is the density of earth, G is the gravitational
constant, r is the radius of the earth and g is acceleration due to gravity.
2) The speed of sound v in a medium depends on its wavelength 1, the young
modulusE, and the density p, of the medium. Use the method of dimensional
analysis to derive a formula for the speed of sound in a medium. (Unit for
Young Modulus E: kgm's 2)
