he drawing shows a square, each side of which has a length of L = 0.250 m. Two different positive charges q1 and q2 are fixed at the corners of the square. Find the electric potential energy of a third charge q3 = -3.00 x

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

An oil slick (n = 1.22) on water (n = 1.33) has a uniform thickness of 517 nm. It is illuminated by white light (400-700 nm) at normal incidence. In the reflected light, find the first wavelength that is a) enhanced and b) missing.

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

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 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*****

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

A highway curve of radius 100m, banked at an angle of 45 degrees, may be negotiated without friction at a speed of?

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.
