The magnetic field created by a large current passing through plasma (ionized gas) can force current-carrying particles together. this pinch effect has been used in designing fusion reactors. it can be demonstrated by making an empty aluminum can carry a large current parallel to its axis. let r represent the radius of the can and i the current, uniformly distributed over the can's curved wall. determine the magnetic field just inside the wall.

Asilver dollar is dropped from the top of a building that is 1324 feet tall. use the position function below for free-falling objects. s(t) = −16t2 + v0t + s0 (a) determine the position and velocity functions for the coin. s(t) = v(t) = (b) determine the average velocity on the interval [1, 2]. ft/s (c) find the instantaneous velocities when t = 1 second and t = 2 seconds. v(1) = ft/s v(2) = ft/s (d) find the time required for the coin to reach the ground level. (round your answer to three decimal places.) t = s (e) find the velocity of the coin at impact. (round your answer to three decimal places.) ft/s
