I would need the correct answers to these examples: 1, What pressure is under the heels of women's pumps? The area of one heel is 1cm2. When calculating, assume that a woman in pumps weighs 60 kg and all her weight is carried only by heels. 2, The bottom of a steel bottle with compressed oxygen has a content of 120 cm2. The oxygen pressure in the bottle is 20MPa. What is the force of oxygen on the bottom of the bottle? 3, Vessels A, B have the same bottom content S = 0.06 m2 and are filled with ethanol. The height of the ethanol level in both vessels is h = 30 cm. Determine the magnitude of the hydrostatic pressure at the bottom of vessel B. 4, Vessels A, B have the same bottom content S = 0.05 m2 and are filled with ethanol. The height of the ethanol level in both vessels is h = 20 cm. Determine the magnitude of the hydrostatic pressure at the bottom of vessel B.
