Section A midterm 2
1. A square loop of wire with sides of length L = 0.17 m and total resistance R = 50 ohms is
moving with constant velocity v into a region of constant magnetic field B = 0.76 T. The
magnetic field is perpendicular to the plane of the l
Modern Physics - Problem 30
When a beam of high-energy protons collides with protons at rest in the laboratory frame,
neutral pions (0) are produced by the reaction p + p p + p + 0. The kinetic energy of
each incoming high-energy proton is Ek'. We want to
