Question

Jorge wishes to observe the progress of his vacuum pump in evacuating a tall bell jar for the purpose of demonstrating that sound waves do not travel in a vacuum. So, Jorge places a mercury barometer inside the bell jar and follows the height of the mercury column as the pump chugs away. When he observes a height of 5.59 mm, what fraction of atmospheric pressure, expressed as a percentage, has Jorge achieved in his bell jar? The density of mercury is 1.36 x 104 kg/m and the standard atmospheric pressure is 1.01 x 10 Pa. The acceleration g due to gravity is 9.81 m/s. fraction of atmospheric pressure:
