1/ A cylinder 1.00 m tall with inside diameter 0.120 m is used to hold propane gas (molar mass 44.1 g/mol). It is initially filled with gas until the gauge pressure is 1.30 x 10^6 Pa and the temperature is 22.0oC. The temperature of the gas remains constant as it is partially emptied out of the tank, until the gauge pressure is 2.50 x 10^5 Pa. Calculate the mass of propane that has been used.
2/ A vertical cylindrical tank contains 1.80 mol of an ideal gas under a pressure of 1.00 atm at 20.0oC. The round part of the tank has a radius of 10.0 cm, and the gas is supporting a piston that can move up and down in the cylinder without friction.
(a) What is the mass of this piston?
(b) How tall is the column of gas that is supporting the piston
Two small spheres hang in equilibrium at the bottom ends of threads, 40.0 cm long, that have their top ends tied to the same fixed point. Find the distance between the centers of the spheres
If the percentage standard error in measuring voltages and currents is 2%, the percentage standard error in measuring the radius of the path is 3%, what is the percentage standard error in finding e/m

A pump, submerged at the bottom of a well that is 34 m deep, is used to pump water uphill to the house that is 50 m above the top of the well, as shown above. All pressures are gauge pressures. Avoid the effects of friction, turbulence, and viscosity..
Blocks with masses of 4.0, 8.0, and 9.0 are lined up in a row on a frictionless table. All three are pushed forward by a 16 force applied to the 4.0 block. How much force does the 8.0 block exert on the 8.0 block.
When two identical ions are separated by a distance of 5.9 10-10 m, the electrostatic force each exerts on the other is 6.0 10-9 N. Evaluate how many electrons are missing from each ion?
