Q. A 320- piano slides 3.3 down a 24 incline and is kept from accelerating by a man who is pushing back on it parallel to the incline. Determine the work done by the man on the piano.
Q. A photon undergoing Compton scattering has a energy after scattering of 80KeV and the electron recoils with an energy of 25Kev. Find the wavelength of the incident photon. Finf the angle at which the photon is scattered. Find the angle at which the electron recoils.
Which of the planets fits the following description: "a solid, cool surface, with occasional dust clouds and a thin CO2 atmosphere".
Coherent light with wavelength 592 nm passes through two very narrow slits, and interference pattern is observed on the screen a distance of 3.00 {rm m} from the slits. The first-order bright fringe is the distance of 4.84 {rm mm} from the center o..
How long will it take you to cover the 99 m length of the walkway if, once you get on the walkway, you immediately turn around and start walking in the opposite direction with a speed of 1.5 m/s relative to the walkway.
Vector A points in the negative y direction and has a magnitude of 3 units. Vector B has three times the magnitude and points in the positive x direction. Find out the direction and magnitude of the following vectors.
A diving board oscillates with simple harmonic motion of frequency 3.36 cycles per second, What is the maximum amplitude with which the end of the board can vibrate in order that the pebble placed there not lose contact with the board during oscillat..
suppose the radius of the ball is very small compared to other length scales in the problem. Take starting level as step 0, the next step down as step 1, and so on.
A hollow cylinder of radius and height has a total charge uniformly distributed over its surface. The axis of the cylinder coincides with the z axis, and cylinder is centered at the origin.
A rifle with a barrel length of 57 fires an 11 bullet with a horizontal speed of 440. The bullet strikes a block of wood and penetrates to a depth of 12. What resistive force (assumed to be constant) does the wood exert on bullet.
As the block has raised a vertical height of 0.725, the tension in the cord is 4.66 .What is the velocity of the bullet originally.
Estimate approximately the angular deflection of the muon's trajectory, given that the rest mass of muon is 100Mev and that the saturation magnetization in iron is equivalent to 1.6 x 10^23 electron moments per cm^3.
The pilot of an aircraft wishes to fly due west in a 37.70 km/h wind blowing toward the south. The speed of the aircraft in the absence of the wind is 191 km/h.
A car of mass = 1300 travelling at 56.0 enters a banked turn covered with ice. The road is banked at an angle, and there is no friction between the road and car's tires. What is the radius of the turn if = 20.0 (assuming the car continues in uniform ..
