Suppose you measure a standing person's blood pressure by placing the cuff on his leg o.500 m below the heart. Calculate the pressure you would observe (in units of mm Hg) if the pressure at the heart were 12o over 80 mm Hg. Assume that there is no loss of pressure due to resistance in the circulatory system (a reasonable assumption, since major arteries are large).

33. Suppose you measure a standing person's blood
pressure by placing the cuff on his leg o.500 m below the
heart. Calculate the pressure you would observe (in
units of mm Hg) if the pressure at the heart were 120
over 80 mm Hg. Assume that there is no loss of pressure
due to resistance in the circulatory system (a reasonable
assumption, since major arteries are large).
69. You can chew through very tough objects with your
incisors because they exert a large force on the small
area of a pointed tooth. What pressure in pascals can
you create by exerting a force of 500 N with your tooth
on an area of 1.00 mm²?
