a square coil of wire containing a single turn is placed in a uniform 0.30 t magnetic field as the drawing shows. each
A 19g ball of clay is shot to the right (in the positive -direction) at 21m/s toward a 38g ball of clay at rest. The two balls of clay collide and stick together. Call this reference frame S. 1. What is the total momentum in frame S?
A gamma-ray telescopes intercept a pulse of gamma radiation from magenta, a type of star with a spectacularly large magnetar field. Determine the magnitude of the rms magnetic field of the gamma-ray pulse
A boxcar of mass 5.68×10^4 kg is rolling south at 2.33 m/s when it collides with, and couples to, another boxcar of mass 5.11 x 10^4 kg which is initially at rest. After collision, what is the velocity of the coupled boxcars?
