Consider a cylindrical capacitor made out of two "long" metal cylindrical shells of length L. The outer one has a radius R and the inner one has a radius r. Now Q Coulombs of charge are removed from the outer cylinder and moved to the inner cylinder. -Using Gauss's Law, derive an expression for the field in the gap between cylindrical shells. Please state the symmetry argument clearly as well as choice for Gaussian surface used and why. -Now that...

Suppose a gas-filled incandescent light bulb is manufactured so that the gas inside the bulb is...

Suppose a gas-filled incandescent light bulb is manufactured so that the gas inside the bulb is at atmospheric pressure when the bulb has a temperature of 20.0°C. Part (a) Find the gauge pressure, in standard atmospheres, inside such a bulb when it is hot, assuming its average temperature is 59.5ºC and neglecting any change in volume due to thermal expansion. Part (b) The actual final pressure for the light bulb will be less than calculated in part (a) because the...

A bottle filled with 0.5 L of an aqueous solution is at equilibrium with the gas containing 70 % (mole fraction) of nitrogen, N2, and 30 % of oxygen, O2. The temperature is 25 oC and the total pressure of the gas is 10 atm. The Henry’s Law constants for nitrogen and for oxygen in the solution are 6.1 × 10-4 mol L-1 atm-1 and 1.3 × 10-3 mol L-1 atm-1 . (i) Calculate the partial pressure of oxygen and...
