C. Blood Pressur 1. The density of blood is 1055 kg/m3. If the blood at the very top of your head exerts a minimum gauge pressure of 45 mm Hg (6000 Pa), estimate the gauge pressure at your heart (0.25 m below the top of your head) in Pa.

Please show work.
Using reasonable estimates of height differences, calculate the blood pressure difference between each of the following and the heart (specifically, pressure at the body part minus pressure at the heart): head, hand, foot. Write the answers in Pa and in mm Hg. Assuming that the pressure at the heart is 120 mm Hg, calculate the pressure at the head, at the hand, and at the foot.

Neglecting the pressure drop due to resistance, calculate the blood pressure, in pascals, in an artery in the brain 30 cm above the heart. The pressure at the heart is 120 mm Hg. The density of blood is 1.05 g/cm2 and the density of mercury is 13600 kg/m2. Do not type in units. Two different manometers are used to read a pressure. One uses water of density 1.0 g/cm3 and reads "150 cm water". The other one uses an unknown...

Help please
Chapter 15, Problem 009 When a .22-caliber rifle is fired, the expanding gas from the burning gunpowder creates a pressure behind the bullet. This pressure causes the force that pushes the bullet through the barrel. Suppose the barrel has a length of 0.611 m and an opening whose radius is 2.75 x 10-3 m. A bullet (mass = 2.6 x 10-3 kg) has a speed of 401 m/s after passing through this barrel. Ignore friction and determine the...

Chapter 07, Problem 009 Your answer is partially correct. Try again. The only force acting on a 1.3 kg canister that is moving in an xy plane has a magnitude of 4.5 N. The canister initially has a velocity of 2.3 m/s in the positive x direction, and some time later has a velocity of 4.0 m/s in the positive y direction. How much work is done on the canister by the 4.5 N force during this time? Number1035 Units...

Chapter 28, Problem 009 In the figure, an electron accelerated from rest through potential difference V1-1.00 kV enters the gap between two parallel plates having separation d- 23.1 mm and potential difference V2 167 V. The lower plate is at the lower potential. Neglect fringing and assume that the electron's velocity vector is perpendicular to the electric field vector between the plates. In unit-vector notation, what uniform magnetic field allows the electron to travel in a straight line in the...
