A voltage of 20 V is connected across a resistor of 5 . Calculate the power dissipated in the resistor.

A particle with a charge of -1.8 μC and a mass of 1.6 x 10 -6 kg is released from rest at point A and accelerates toward point B, arriving there with a speed of 64 m/s. The only force acting on the particle is

A)True or False? If there is no applied electric field in a conductor, the average drift velocity of the electrons in the metal is zero.

Four identical charges (+2.8 μC each) are brought from infinity and fixed to a straight line. Each charge is 0.36 m from the next. Determine the electric potential energy of this group.

A sphere of radius R has a radius dependent charge density ρ = B · r3 in terms of R and B.

How to calculate the capacitance in a circuit knowing the inductance?

A coating of film n = 1.33 on glass slabs (n = 1.6) is 8.4×10−5cm thick. If white light is incident normally, which visible wavelengths are missing in the reflected light? White light containing wavelengths from 400 to 700 nm. Answer from high to low*****

Assuming frictionless conditions, a table has a hanging mass, m1, over a pulley at the left side and another hanging mass, m2, over a pulley on the right side. These two masses are connected to a third mass, m3, resting on the table surface. Light

A thin film of oil (n = 1.4) of thickness 1.4micrometers. is compressed between two glass slabs (n = 1.5). White light containing wavelengths from 400 to 700nm (measured in air) is incident normally on the film. In the reflected light, which wavelengths (from long
