1.) Light of wavelength 0.50 ?m illuminates a soap film (n = 1.33). What is the minimum thickness of film that will give an interference when the light is incident normally on it?
2.) A glass plate 2.5 cm long is separated from another glass plate by a strand of someone's hair (diameter 0.010 mm). How far apart are the adjacent interference bands when viewed with light of wavelength 600 nm?
Two positive charges of 7.40 micro-Coulombs are placed on a horizontal surface with a coefficient of static friction 0.72. If they are originally far apart.
An air conditioner is used to keep the interior of a house at a temperature of 25C while the outside temperature is 34C a)If heat leaks into the house at the rate of 11kW, and the air conditioner has the efficiency of a Carnot engine, what is the ..
Two square metal plates are placed parallel to each other, separated by a distance d= 2.04 cm. The plates have sides of length L = 0.580 m. One of the plates has charge Q= + 1.86×10-6 C, while the other plate has charge -Q. Calculate the magnitude..
Heather and Jerry are standing on a bridge 51 above a river. Heather throws a rock straight down with a speed of 12. Jerry, at accurately the same instant of time, throws a rock straight up with the same speed. Ignore air resistance.
A box of 10 kg is being pulled across a floor with a tension force of 50 N. Assume the box started from rest and reached a speed of 2 m/s
Assume a ray of light is incident on an air / material boundary at 45 degrees to the normal. What is the critical angle for the material when it is surrounded by air
Now suppose the gliders in the previous problem collide completely inelastically so that they stick together rather than rebounding off each other after they collide. Compare the initial and final kinetic energies
A person drops a cylindrical steel bar (Y = 6.0 × 1010 Pa) from a height of 2.00 m (distance between the floor and the bottom of the vertically oriented bar). The bar, of length L = 0.58 m, radius R = 0.50 cm, what is the maximum compression of the..
