A circular loop of wire is in the plane of the paper. The north pole of a bar magnet is being moved toward the center of the loop from a position in front of the paper. The direction of the induced current in the loop:. a) is north. b) is south. c) is counterclockwise. d) is clockwise. d) cannot be determined.

counterclockwise

Explanation:

By applying Lenz's Law, as the North pole of the magnet approaches the center of the loop, the inducing magnetic flux through the loop is increasing., and therefore, the induced flux will be in the direction opposite to the magnetic field B of the magnet. Such will cause a counterclockwise current in the loop, using the right hand rule.

would be false hope this out

air exerts forces on falling objects near earth’s surface.

explanation:

the term 'free falls' refer to object that are falling towards the earth, in a situation in which gravity is the only force acting on the object.

for an object in free fall, the acceleration is constant (g, the gravitational acceleration), and so the velocity of the object constantly increases.

for objects near earth's surface, there is always another force acting on the object: the resistance due to the air. this force is opposed to the direction of fall of the object, and it is proportional to the velocity of the object, so as the object falls down, this force increases up to a point when it balances the force of gravity, and the object continues its motion at constant velocity (called terminal velocity). since in this case gravity is not the only force acting on the object, we are not in a situation of free fall.
