A 2D plane is divided into two haves. In one half, a constant magnetic field of 3 T points out of the page. In the other the magnetic field is zero. A square wire of side 4 m is half-way into the magnetic field region. It is being pulled out with a speed of 5 m/s. What is the emf enduced in the wire?

Let f(x) = x4- 8x2 . find the relativeextrema of this function using the second derivative test.

The velocity of car is 80.0 miles per hour. what is the velocity of car in meters per second? (1 km -0.621 miles) m/s

The x-coordinate of a particle in curvilinear motion is given by x = 3.1t3 - 4.9t where x is in feet and t is in seconds. the y-component of acceleration in feet per second squared is given by ay = 2.3t. if the particle has y-components y = 0 and vy = 5.0 ft/sec when t = 0, find the magnitudes of the velocity v and acceleration a when t = 1.8 sec. sketch the path for the first 1.8 seconds of motion, and show the velocity and acceleration vectors for t = 1.8 sec. answers: v = ft/sec a = ft/sec2
