Two glass marbles (1 and 2), each supported by a nylon thread, are rubbed against a piece of silk and then are placed near a third glass marble (3), also supported by a similar thread. Assuming that marble 3 has not been in contact with the piece of fabric, which of the following statements best describes the situation when the three marbles are brought together?To keep things simple in this Tutorial, we will ignore the effects of polarization and just focus on the overall charge of each object. a.) Marbles 1 and 2 attract each other, but no interaction occurs with marble 3.b.) Both marbles 1 and 2 attract marble 3.c.) The three marbles will repel each other. d.) Marbles 1 and 2 repel each other, but no interaction occurs with marble 3.

Suppose a wheel with a tire mounted on it is rotating at the constant rate of 2.15 times a second. a tack is stuck in the tire at a distance of 0.373 m from the rotation axis. noting that for every rotation the tack travels one circumference (a) find the tack's tangential speed. (b) what is the tacks radial acceleration?
