The pressure exerted by a phonograph needle on a record is surprisingly large. If the equivalent of 0.500 g of mass is supported by a needle the tip of which is a circle 0.180mm in radius, what pressure is exerted on the record in N/m2? _N/m2
The pressure exerted by a phonograph needle on a record is surprisingly large, due to the very small width of the needle. If the equivalent of 0.85 g is supported by a needle, the tip of which is a circle 0.175 mm in radius, what pressure is exerted on the record, in pascals?
Solve and please explain steps elaborately

(a) Calculate the pressure exerted by a phonograph needle on a record if the needle supports 2.00 g on a circular area whose circumference is 0.500? ??. (b) Express this pressure in newtons per square meter and in atmospheres
A patient in the hospital is receiving a saline solution through a needle in their arm. The needle is 2.20 cm long, horizontal, with one end in a vein in the arm, and the other end attached to a wide tube that extends down from the bag of solution, which hangs from a pole so that the fluid level is 90.0 cm above the needle. The inner radius of the needle is 0.250 mm. The top of the fluid is...
A person pushes with a force of 10.0 N on a stick pin to try to push it into a bulletin board.

A large-capacity faucet is to be connected to a water main by 20-mm-diameter copper tubing as shown in figure. The copper tubing has an estimate surface roughness of 0.003 mm, and local head losses are created by the corporation stop (C-stop), four bends, and the faucet itself. The faucet exi diameter of 12 mm. What minimum pressure in the water main is require obtain a desired flow rate of 50 L/min when the faucet is wide open? At 20°C, the...
Need help filling in my data sheet from a lab. My professor said
the pressure was 24.6 inches of Hg and that we needed to convert
that to moles. Im not sure i put that in the correct spot. I
included the lab protocol. Plz plz plz help me fill in the blanks
and let me know if i did something wrong Im very confused haha.
THANKS!!

In a water pistol, a piston drives water through a larger tube of radius 1.30 cm into a smaller tube of radius 1.10 mm as in the figure below. A diagram shows the interior of a water pistol pointing to the right, and the flow of water through it. The left end of the trigger is connected to the piston on the right end of a cylinder. The left end of the cylinder is connected to a tube, such that...
