The container shown is filled with mercury. It is open to atmosphere on the left and closed on the right. What is the pressure at point B, in kPa (kiloPascal)? ⍴mercury = 13,600 kg/m3,1.00 atm = 1.00 × 105 Pa = 100 kPa, and g = 10.0 m/s2.

A 72.0-kg man lies on his back on a bed of nails, with 1,202 of the nails in contact with his body. The end of each nail has area 1.14 ✕ 10−6 m2. What average pressure is exerted by each nail on the man's body?

A manometer containing water with one end connected to a container of gas has a column height difference of  h = 0.27 m  (see figure below). If the atmospheric pressure on the right column is 1.01 ✕ 105 Pa, find the absolute pressure of the gas in the container. The density of water is 1.0 ✕ 103 kg/m3. Pa

What is the pressure inside the drop of mercury of radius 3.00 mm at room temperature? Surface tension of mercury at that temperature (20°C) is 4.65 x 10 N m. The atmospheric pressure is 1.01 x 10° Pa. Also give the excess pressure inside the drop.

A manometer containing water with one end connected to a container of gas has a column height difference of h = 0.31 m (see figure below). If the atmospheric pressure on the right column is 1.01 ✕ 105 Pa, find the absolute pressure of the gas in the container. The density of water is 1.0 ✕ 103 kg/m3. Pa

Problem 1:  A certain rigid aluminum container contains a liquid at a gauge pressure of P0 = 2.02 × 105 Pa at sea level where the atmospheric pressure is Pa = 1.01 × 105 Pa. The volume of the container is V0 = 2.15 × 10-4 m3. The maximum difference between the pressure inside and outside that this particular container can withstand before bursting or imploding is ΔPmax = 2.41 × 105 Pa.For this problem, assume that the density of air maintains a constant value of ρa = 1.20 kg / m3 and that the density of seawater maintains a constant value of ρs = 1025 kg / m3. What is the maximum depth dmax in meters below the surface of the ocean that the container can be taken before imploding?

You are with an excursion party on an exploration of the surface of Mars. You find a small lake of water of that 1.76 m. Assume the density of the freshwater is unchanged on Mars. You measure the absolute pressure at the bottom of the lake to be one 161,800 Pa. What is the absolute pressure (in atm) at the surface of the lake. Assume the value of G on Mars is 3.72 m/s^2

Water is discharged from a pipeline at a velocity v given by v=1340*squarerootof p, where p is the pressure in (psi). If the water pressure is changing at a rate of 0.47 psi/second, find the acceleration (dv/dt) of the water when p=20 psi. Round the answer to two decimal places. dv/dt=

Part A -  A cube of volume 3.0 ×10-3 m3 (3.0 L) is placed on a scale in air. The scale reads 267 N.
