Yoon ki investigates electromagnetic induction by moving a bar magnet into a coil of wire. his experimental setup is shown. what change would most improve his results? moving the magnet faster using more loops of wire in the coil using the south pole of the magnet connecting the galvanometer to the coil

According to newton’s first law of motion, which force is expected to cause a body to accelerate?

What is the average speed of a car that travels 40 mph for 1 hour and 60 mph in another hour?

At a certain instant after jumping from the airplane a, a skydiver b is in the position shown and has reached a terminal (constant) speed vb = 52 m/s. the airplane has the same constant speed va = 52 m/s, and after a period of level flight is just beginning to follow the circular path shown of radius ρa = 2330 m. (a) determine the velocity and acceleration of the airplane relative to the skydiver. (b) determine the time rate of change of the speed vr of the airplane and the radius of curvature ρr of its path, both as observed by the nonrotating skydiver.
