A narrow beam of light with wavelengths from 450 nm to 700 nm is incident perpendicular to one face of a 32.00? prism made of crown glass, for which the index of refraction ranges from n=1.533 to n=1.517 for those wavelengths.
What is the angular spread of the beam after passing through the prism? Express your answer using four significant figures.
What is the height of the hill . Find the coefficient of kinetic friction between flight bag and floor.
At what speed does the speed of the ball change relative to the cab floor (sign and magnitude)?
suppose that the engineer is at x = 0 when, at t = 0, he first spots the locomotive. Sketch x(t) curves for the locomotive and high-speed train for the cases in which a collision is just avoided and is not quite avoided. Do this on paper. Your ins..
Two bicycle tires are set rolling with the equivalent initial speed of 5.0 m/s along a long, straight road, and distance each travels before its speed is reduced by half is measured. One tire is inflated to a pressure of 40 {rm psi} and goes the dist..
The coefficient of friction between his clothes and Earth is 0.70. He slides so that his speed is zero just as he reaches the base. Evaluate how far does he slide?
A 57-kg pole vaulter running at 1.1 m/s vaults over the bar. Her speed while she is above the bar is 1.0 m/s. Avoid air resistance, as well as any energy absorbed by the pole, and determine her altitude as she crosses the bar.
What is the magnitude of the acceleration caused by magnetic force? Ignore the gravitational force acting on the electron.
A cluster of galaxies has a radius of about 5.2 million light-years (4.9×10^22) and an intracluster medium with a temperature of (6.5×10^7) K. Estimate the mass of the cluster. Give the answer in both kilograms and solar masses. Suppose combined l..
Suppose you have an electric hot water heater for your house which is an aluminum cylinder which has a 0.6 m radius and is 1.2 m high. The walls are 1.0 cm thick.
A hawk flies in a horizontal arc of radius 14 m at a constant speed of 5 m/s. (a) Find out its centripetal acceleration. (b) It continues loftly along the same horizontal arc but increases its speed at the rate of 1 m/s2. Find out the acceleration..
A stone of mass 0.31 kg is tied to a string of length 0.85 m and is swung in the horizontal circle with speed v. The string has a breaking-point force of 90 N. What is the largest value v can have without string breaking.
if an acoustic wave from an echo sounder on a ship take .30 seconds to reach the sea-floor and reflected wave returns to the boat in .30seconds how deep is the water.
