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.

Aprojectile is launched from ground level with an initial velocity of v 0 feet per second. neglecting air resistance, its height in feet t seconds after launch is given by s equals negative 16 t squared plus v 0 t. find the time(s) that the projectile will (a) reach a height of 192 ft and (b) return to the ground when v 0equals112 feet per second. (a) find the time(s) that the projectile will reach a height of 192 ft when v 0equals112 feet per second. select the correct choice below and, if necessary, fill in the answer box to complete your choice.
