When driven by a 124 Hz vibrator, a string has transverse waves of 26 cm wavelength travelling along it.

three point charges lie along the x axis as shown in the figure (no figure was given). the positive charge q1=15 mc is at x=2 m, the positive charge q2 =6 mc is at the origin, and the resultant force acting on q3 is 0.

A box is on the ramp of a parked moving-truck that forms an angle = 33 degrees with the horizontal. You are currently pushing horizontally (relative to Earth) on the box with a force Fyb=479 N to keep it from sliding down. The mass of

An AC power source has an rms voltage of 2.30 ✕ 10 2 V and operates at a frequency of 50 Hz. If a series RLC circuit is made from the power source, a 0.820 μF capacitor, a 11.0 H inductor and a 1.70 ✕

When using a double slit with light of wavelength 550 nm, it is observed that the 4-th order maximum of the interference pattern occurs at the positions of the first minimum in the diffraction pattern. If the width of the slits is 0.39 mm, what

A thin, circular disk of radius 30.0 cm is oriented in the yz-plane with its center at the origin. The disk carries a total charge of +3.00 μC distributed uniformly over its surface. Calculate the magnitude of the electric field due to the disk at

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*****

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 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
