A rubber stopper attached to a string is travelling in a circular path above a students' head. If the radius of the circle that the stopper is travelling is 0.5m and it takes 2.0 s for the stopper to make one complete revolution, what is the velocity of the rubber stopper?

probably not the "magnets"in the magnet, so to speak, are thought to be electrons orbiting in shells. vurrent loops two sides to the loop

hi there!

out of the two, (b) precision would be more reasonable.   however, both a and b could be pretty reasonable.
