Calculate the difference in blood pressur toes of a human by treating the blood as a static fluid (this is a very crude approximation because there is a pump which is making the blcod flow). assume that the person is 187 cm tall and that the density of bloc d is 1060 kg/m3 use g=10 m/s2). for comparison, normal blood pressure is about 880 mm hg = 117 kpa, this comprises 760 mm hg of atmospheric pressure and 120 mm hg of relative pressure
the difference in blood pressure is kpa

19.822 kPa

Explanation:

= Density of blood = 1060 kg/m³

g = Acceleration due to gravity = 10 m/s²

h = Height of person = 187 cm

The pressure difference would be given by the relation (as there are no other forces to be considered)

The difference in blood pressure is 19.822 kPa

it's when something is going so fast it makes a loud noise, breaking the sound barrier, for example: a jet makes a loud noise, not only cause of the jet but because they reached a point where they went so fast that you can year the noise from various parts, kinda like a police car, lets say the car was going   so fast that you hear the siren of the cop car right next to you, but the car is probably a mile a way, it's cos the siren was next to you a few seconds if you understand me
