You push the spring of a 42 g popper toy down 3.0 cm to lock the suction cup down. When it pops up, it goes straight up to its maximum height 35 cm above the spring’s equilibrium point. a) Calculate the spring constant. (348 N/m) b) What force was used to push the popper down initially? (10.4 N)
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.
Hi, please show full solutions and also explain how you get the answers in physics terms so it's understandable. The correct final answers are written beside too. This is one whole question to be answered. I can't post it separately since it's related. Thank you.
