Question

17) A full-term fetus typically has a mass of 3.50 kg. a) What pressure does the weight of a fetus create if the fetus is supported on an area of 90 cm directly above the mother's bladder? b) Convert this pressure to millimeters of mercury and determine if it alone is great enough to trigger the micturition reflex which requires a pressure of 25 mm Hg.

could I get some help with this problem part a & b. I'm unclear how to solve.

Answer 1

Force -- mg - A) Pressure - Force - 3.50 x 4.8 - 36 X103 / m2 Area 90 x 154 m² = #Omm Hg = 1 Paxl.com 325 Immity = 101325 260 (Pressure) Pa X 760 = Pressure in Hg. T0 1325 Pressure in Hg = Pressure (Pa) in 0.0075 » 3.8 x103 x 0.0075= 28.54g It is enough to trigger Scanned with CamScanner
