A sample is bombarded by incident X-rays, and free electrons in the sample scatter some of the X-rays at an angle of -0= 122.0 degrees with respect to the incident X-rays (see Figure 29.10). The scattered X-rays have a momentum whose magnitude is 1.856 x 10^-24 kg *m/s. Determine the wavelength (in nm) of the incident X-rays. (For accuracy, useh=6.626x10^-34 J*s,c=2.998x10^8 m/s,andm=9.109x10^-31 kg for the mass of an electron.)
Determine the direction of the net electrostatic force on charge q3 (angle with respect to the positive x-axis).
An airplane is flying with a velocity of 83.0 at an angle of 25.0 above the horizontal. When the plane is a distance 114 directly above a dog that is standing on level ground, the suitcase drops out of the luggage compartment.
What current is in the primary circuit. A proton moves at a speed of 8.0 103 m/s as it passes through a magnetic field of 0.55 T. Find the radius of the circular path. Note down that the charge carried by the proton is equal to that of the electron..
On a frictionless table, a glob of clay of mass 0.24 kg strikes a bar of mass 1.34kg perpendicularly at a point 0.38m from the center of the bar and sticks to it. If the bar is 1.14 m long and the clay is moving.
If the coefficient of friction between the block and the floor is 0.40, what is the mass of the block.
A 36.0 g bullet moving at 478 m/s strikes a 3.7 kg bag of flour that is on ice, at rest. The bullet passes during the bag, leaving at 255 m/s. How fast is the bag moving when the bullet exits.

A person with a mass of 71.6 kg and a volume of 0.089 m3 floats quietly in water. (a) What is the volume of the person that is above the water?
A 7.00 kg bowling ball moves at 2.30m/s. How fast must a 2.60g Ping-Pong ball move so that the two balls have the same kinetic energy.
A person weighing 700N on a wire. find the tension force in the two segments of the wire. left wire 20 degrees and right wire 40 degrees.
Seismographs measure the arrival times of earthquakes with a precision of 0.100 s.7 To get the distance between to the epicenter of the quake, they compare the arrival times of S- and P-waves, which travel at different speeds.
A uniform rod of length 0.790 m and mass 14.50 kg is balanced on a sharp edge at 0.650 m from the left end. At the left end hangs a mass of 45-kg and the right end hangs an unknown mass so that the whole assembly is in equilibrium.
