A sample of argon gas occupies a volume of 8.95 L at 45 oC and 0.931 atm.

If it is desired to increase the volume of the gas sample to 11.0 L, while increasing its pressure to 1.12 atm, the temperature of the gas sample at the new volume and pressure must be oC.

According to Coulombs Law, two like electrical charges repel each other with a force that is inversely proportional to the square of the distance between them. If the force of repulsion is 10 dynes (1 dyne = 10E-5 newton) when they are 2 cm apart, find the work done in bringing the charges from 5 cm apart to 1 cm apart.

The flywheel has mass 39.0 kg and diameter 78.0 cm. The power is off for 28.0 s and during this time the flywheel slows due to friction in its axle bearings. During the time the power is off, the flywheel makes 180 complete revolutions. At what rate is the flywheel spinning when the power comes back on? How long after the beginning of the power failure would it have taken the flywheel to stop if the power had not come back on? How many revolutions would the wheel have made during this time?

I've tried so many times and the problem is so simple...

Consider the given curves to do the following:

y = 2 - (x^2)
y = x^2

Use the method of cylindrical shells to find the volume V generated by rotating the region bounded by the given curves about x = 1.
