Aflat, circular loop has 20 turns. the radius of the loop is 10.0 cm and the current through the wire is 0.50 a. determine the magnitute of magnetic field at the center of the loop.

Consider two less-than-desirable options. in the first you are driving 30 mph and crash head-on into an identical car also going 30 mph. in the second option you are driving 30 mph and crash head-on into a stationary brick wall. in neither case does your car bounce off the thing it hits, and the collision time is the same in both cases. which of these two situations would result in the greatest impact force?
