An electron has an initial velocity of (17.1 + 12.7) km/s, and a constant acceleration of (1.60 * 1012 m/s2) in the positive x direction in a region in which uniform electric and magnetic fields are present. If = (529 µT) find the electric field.

A uniform narrow tube 1.80 m long is open at both ends. It resonates at two successive harmonics of frequencies 280 Hz and 300 Hz. (a) What is the fundamental frequency (Hz) ? (b) What is the speed of sound in the gas in the tube (m/s) ?
