A 0.658-nm photon collides with a stationary electron. After the collision, the electron moves forward and the photon recoils backwards.
(a) Find the momentum of the electron.
(b) Find the kinetic energy of the electron.
Suppose 1.0 mol of a monatomic ideal gas initially at 10 L and 348 K is heated at constant volume to 696 K, What is the efficiency of the cycle
The total electric field consists of the vector sum of two parts, Find the magnitude and direction of the total field, Specify the directional angle relative to the x axis
A proton is initially at rest at a point where the potential is 507V. Sometime later the proton is at a point where the potential is 187V. If no force other than the electrostatic force acts on the proton, what is its final kinetic energy.
A person with perfect pitch sits on a bus bench listening to the 450 Hz horn of an approaching car. If the person detects the frequency of 470 Hz, how fast is the car moving.
A 23 g ball is fired horizontally with initial speed toward a 110 g ball that is hanging motionless from a 1.1m long string. The balls undergo a head on, perfectly elastic collision, after which the 110 g ball swings out to a maximum angle theta m..
An 82 g arrow is fired from a bow whose string exerts an average force of 95N on the arrow over a distance of 77.00 cm. What is the speed of the arrow as it leaves bow.
A tennis player standing 10.7 m from the net hits the ball at 2.50° above the horizontal. how fast was the ball moving when it left the racquet
The speed limit for both roads is 35 mi/h, and the driver of the northward-moving vehicle claims he was within the speed limit when the collision occurred.
A wooden dowel (cylinder) has a diameter of 2.20 cm. Determine the density of the dowel
What is the minimum rate of rotation, in revolutions per minute, required for the spheres to contact the cylinder wall?
What is the maximum rate of rotation. A moving electron passes near the nucleus of a gold atom, which contains 79 protons and 118 neutrons. At a particular moment electron is a distance of 7.5 x10 ^9 m from the gold nucleus.
If the company is presently selling 45,000 units, but plans to spend an additional $108,000 on an advertising program, explain how many additional units must the company sell to earn the same net income it is now making?
