In a Compton scattering experiment, an x-ray photon scatters through an angle of 18.0° from a free electron that is initially at rest. The electron recoils with a speed of 2500 km/s.
(a) Calculate the wavelength of the incident photon. nm
(b) Calculate the angle through which the electron scatters.
A chair of mass 13.0kg is sitting on the horizontal floor; the floor is not frictionless, Use Newton's laws to calculate the normal force that the floor exerts on the chair
She pumps the handle up and down, slowly lifting the car. What is the force exerted on the small piston during each downward stroke?
What is the net force exerted by these two charges on the third charge = 46.5 placed between and at = -1.235 ? Your answer may be positive or negative, depending on direction of the force.
The square loop shown is made of wires with a total series resistance of 10 W. It is placed in a uniform 0.100-T magnetic field directed perpendicular into the plane of the paper.
A horizontal block-spring system with the block on a frictionless surface has total mechanical energy E = 49.2 J and a maximum displacement from equilibrium of 0.280 m.
The base of the cloud, which is roughly parallel to the Earth's surface, serves as the negative plate and the region of Earth's surface under the cloud serves as the positive plate. The separation between the cloud base and the Earth's surface is ..
Calculate the threshold wavelength, in nm, of a metal if that metal emits an electron with a kinetic energy of 6.32 × 10-19 J when illuminated with light that has a frequency of 1.97 × 1015 Hz.
Suppose one gallon of gasoline produces 1.1 × 108 J of energy, and this energy is sufficient to operate a car for twenty miles. how many miles could the car go with that energy
