A light beam containing red and violet wavelengths is incident on a slab of quartz at an angle of incidence of 50.7°. The index of refraction of quartz is 1.455 at 660 nm (red light), and its index of refraction is 1.468 at 410 nm (violet light). Find the dispersion of the slab, which is defined as the difference in the angles of refraction for the two wavelengths.
A rubber ball of mass m falls straight down and bounces off the floor with equal incoming and outgoing speeds v. What is the magnitude of the impulse on the ball
Rank the voltage across each cylinder. A baseball is seen to pass upward by a window 15 m above the street with a vertical speed of 18 m/s. imagine the ball was thrown from the street. What was it's initial speed.
A pendulum is made out of a ( 251.3+-0.1)g mass and a string that is (1.3+-0.005)m long. If the mass has a speed of (1.3+-0.1)m/s, Calculate the tension of the string and its uncertainty
What is an average velocity of the train throughout run
A student throws a set of keys 4.4m up to friend in window. the friend catches the keys 1.7s later. what is the intial velocity
A coffee cup heater and a lamp are connected in parallel to the same 120-V outlet. Find the resistance of the lamp
An ideal monatomic gas expands isothermally from 0.600 m3 to 1.25 m3 at a constant temperature of 600 K. If the initial pressure is 1.10 105 Pa. Find the work done on the gas
A ball of mass 1.020 g and positive charge q =45.2 microC is suspended on a string of negligible mass in a uniform electric field. We view that the ball hangs at an angle of theta=15.0 from the vertical. What is the magnitude of the electric field.
A 2.4-kg block is dropped from a height of 5.0 m onto a spring of spring constant 3955 N/m. When the block is momentarily at rest, the spring has compressed by 25 cm.
A ball is released from rest on a no-slip surface, as shown. After reaching its lowest point, the ball begins to rise again, How high does the ball rise on the frictionless side
At t1 = 5.00 s, the acceleration of a particle moving at constant speed in counterclockwise circular motion is a1=(2m/s^2)i + (9m/s^2)j At t2 = 6.00 s (less than one period later), the acceleration is a2= (9m/s^2)i - (2m/s^2)j The period is more t..
The block starts at the top of the wedge at 1.2 m. Find out the final speeds of a block and the wedge once the blook has slid to the bottom.
