    Giraffe Blood Pressure: Calculating Gauge Pressure at the Brain

    In a giraffe with its head 2m above its heart , and its heart 2m above its feet, the hydrostatic gauge pressure in the blood at its heart is 250 torr . Assume that the giraffe stands upright and the blood density is 1.06 * 1000kg/cubic metre.In torr find the (gauge) blood pressure at the brain.

    Coefficient of Friction and Normal Force

    Now read this.. When the surface area is reduced , the pressure on the contact points between the two surfaces increases. As a result some contact points undergo deformity in shape and hence more number of contact points are obtained (imagine the contact points to be like mountains if the height...

    Coefficient of Friction and Normal Force

    if area is halved then pressure wud double (force remains same throughout-normal reaction force). could u put forward ur point properly
