Acoil lies flat on a level tabletop in a region where the magnetic field vector points straight up. the magnetic field suddenly grows stronger. when viewed from above, what is the direction of the induced current in this coil as the field increases? a. counterclockwiseb. clockwise initially, then counterclockwise before stoppingc. clockwised. there is no induced current in this coil

We found the centripetal acceleration of the earth as it revolves around the sun. compute the centripetal acceleration of a point on the surface of the earth at the equator caused by the rotation of the earth about its axis. (enter the magnitude. the radius of the earth is 6,371 km.)

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

Determine the age of a fossil if it had only one eighth of its original carbon-14 content remaining?
