Along, straight wire with 5 a current flowing through it produces magnetic field strength 2 t at its surface. if the wire has a radius r, where within the wire is the field strength equal to 51 % of the field strength at the surface of the wire? assume that the current density is uniform throughout the wire. (μ 0 = 4π × 10-7 t · m/a)

Aprojectile is launched horizontally 10m above the ground and with an initial velocity of 15 m/s. a) sketch the trajectory using an appropriate coordination system. b) how long for the projectile to reach the ground. c) how far did projectile travel horizontally before striking the ground. d) determine the projectilex & y position at t-1.3s e) determine the magnitude and direction of projectile velocity at t= 1.3s f) determine the magnitude and direction of projectile acceleration at t-1.3s

From center station, a train departs every 30 minutes on the fast line and a train departs every 50 minutes on the state line. if two trains depart from center station at 8: 00 a.m., one on each of the two lines, what is the next time that two trains, one on each line, will depart at the same time?
