Of a Circuit Sami wants to construct a model of an
electric circuit to make the motor rotates. He
has the following electric components shown
in the adjacent diagram.

11.2- How many connecting wires should he
use to construct this circuit?

Abar magnet cut in half will form a total ofpoles.a)fourb)eightc)two

Select the correct answer. what does the process of natural selection involve?

To place a communications satellite into a geosynchronous orbit at an altitude of 22,240 mi above the surface of the earth, the satellite first is released from a space shuttle , which is in a circular orbit at an altitude of 185 mi, and then is propelled by an upper-stage booster to its final altitude. as the satellite passes through a, the booster's motor is fired to insert the satellite into an elliptic transfer orbit. the booster is again fired at b to insert the satellite into a geosynchronous orbit. knowing that the second firing increases the speed of the satellite by 4810ft/s, determine (a.) the speed of the satellite as it approaches b on the elliptic transfer orbit, (b.) the increase in speed resulting from the first firing at a.
