A mixture if oxygen and cyclo propane gas is used as an anesthetic. Cycloprapane contains 14.3%H and 85.7% C by mass. At 50.0C and 0.984 atm pressure, 1.56 g cycloprapane has a volume of 1.00L. Determine the molecular formula of cyclopropane?
The two masses are joined altogether by a mass-less rod of length 1. One mass is one third the mass of the other. They are rotating with the angular velocity of w. Determine the moment of inertia and write down their angular momentum.
A hole is drilled in the mass-less rod system from the first question. This hole is one third 1 from the larger mass. When a peg is placed via the hole and the system is now rotating around this peg at the similar w, determine the latest moment of
