Compressed air can be pumped underground into huge caverns as a form of energy storage. The volume of a cavern is7.5 × 105m3, and the pressure of the air in it is7.1 × 106Pa. Assume that air is a diatomic ideal gas whose internal energy is given by U = (5/2)nRT. If one home uses 30.0 kWh of energy per day, how many homes could this internal energy serve for one day?
A copper wire, whose cross-sectional area is 5.22 x 10-6 m2, has a linear density of 5.86 x 10-3 kg/m and is strung between two walls. At the ambient temperature, a transverse wave travels with a speed of 43.1 m/s on this wire. The coefficient of ..
A 0.30 kg mass is suspended on a string. In equilibrium the mass stretches the spring 2.0 cm downward. Calculate the total energy of the system
The emission spectrum of one electron atoms in the Bohr model that assumes that the atom remains at rest through the emission disagrees slightly with observation. Why is this and are the observed wavelengths longer or shorter than those predicted by ..
calculate the ratio of the rates of stimulated emission to spontaneous emission for a hene laser operating at 632.8nm.
Consider a parallel-plate capacitor with an area of 0.9 cm2, with a plate spacing of0.19 mm, and filled with quartz. At what voltage will this capacitor exhibit dielectric breakdown?
