Explain why (a) The blood pressure in humans is greater at the feet than at the brain. (b) Atmospheric pressure at a height of about 6 km decreases to nearly half of its value at the sea level, though the height of the atmosphere is more than 100 km. (c) Hydrostatic pressure is a scalar quantity even though pressure is force divided by area. Answer: (a) The height of the blood column is more for the feet as compared to that for the brain. Consequently, the blood pressure in humans is greater at the feet than at the brain. (b) The variation of air-density with height is n...
