Fluid Pressure
The term fluid pressure is coined as, the measurement of the force per unit area of a given surface of a closed container. It is a branch of physics that helps to study the properties of fluid under various conditions of force.
Gauge Pressure
Pressure is the physical force acting per unit area on a body; the applied force is perpendicular to the surface of the object per unit area. The air around us at sea level exerts a pressure (atmospheric pressure) of about 14.7 psi but this doesn’t seem to bother anyone as the bodily fluids are constantly pushing outwards with the same force but if one swims down into the ocean a few feet below the surface one can notice the difference, there is increased pressure on the eardrum, this is due to an increase in hydrostatic pressure.
i need help with this please
![12. A 30° ramp of height h = 0.80 meters sits near the top of a cliff, as shown. Box 1, of mass m =
1.0 kg and initially at rest, slides down the ramp and along the top of the cliff, eventually colliding
head-on with box 2. Assume that the bottom of the ramp is rounded so that box 1 exits the ramp
smoothly, without bouncing or slowing down, and that the boxes in this problem slide without
friction. Box 2 has mass 2m = 2.0 kg, and was motionless before the collision. After the collision,
box 1 is motionless. The collision knocks box 2 off the cliff. Box 2 flies through the air, eventually
landing an unknown distance d from the bottom of the cliff, which is H = 5.0 meters high. a) Was
the collision perfectly elastic? Defend your answer quantitatively. b) Solve for d in meters.
