Problem 4:
a)What is the source of all types of fossil ( depleted) energy on earth
b)- The basic barometer can be used to measure the height of a building. If the barometric readings at the
top and at the bottom of a building are 730 and 755 mm Hg, respectively, determine the height of the
building. Take the densities of air and mercury to be 1.18 kg/m3 and 13,600 kg/m3, respectively
