3line segments of linear charge density , extending from the origin to (a,0,0) along x-axis, (0,b,0) along y-axis and (0,0,c) along z axis. find the diople moment for this charge distribution, find the first two terms in the multipole expansion of the potential v(0,0,z) on the z-axis for z> > a, b,c.

Oxygen undergoes an isentropic expansion from 120 degree c and 280 kpa absolute to 140 kpa absolute. determine the final temperature of the oxygen and the amount of work per kg of o_2 produced in the process if it is adiabatic.

Amother used 150 watts of power to raise a 15 newton object in a time interval of 8.0 seconds. through what vertical distance was the object raised ?

You have a resistor and a capacitor of unknown values. first, you charge the capacitor and discharge it through the resistor. by monitoring the capacitor voltage on an oscilloscope, you see that the voltage decays to half its initial value in 3.00 ms . you then use the resistor and capacitor to make a low-pass filter. what is the crossover frequency fc?
