A very long, straight wire carries a current of 16.3 A out of the screen. An electron outside the wire is 1.47 cm to the right of the central axis of the wire and is moving with a speed of 3.27×106m/s.
Find the magnitude of the magnetic force on the electron if it is moving directly away from the wire (i.e., rightward).
Find the magnitude of the force on the electron if it is moving parallel to the wire in the direction of the current (i.e., out of the screen).
Find the magnitude of the force on the electron if it is moving upward.
What is the most amounts by which the wavelength of an incident photon could change when it undergoes Compton scattering from an atom or molecule with a 19 u mass .
A 1200 crate slides 15 down a ramp that makes an angle of 30 with the horizontal.If the crate slides at a constant speed, how much thermal energy is created?
A 140-m-wide river flows due east at a uniform speed of 3.9 m/s. A boat with a speed of 7.8 m/s relative to the water leaves the south bank pointed in a direction 39o west of north. How long does it take for the boat to cross the river
