Atransmission line that has a resistance per unit length of 2.40 10-4 ω/m is to be used to transmit 5.00 mw across 400 mi (6.44 105 m). the output voltage of the source is 4.50 kv. (a) what is the line loss if a transformer is used to step up the voltage to 506 kv? (b) what fraction of the input power is lost to the line under these circumstances? (c) what difficulties would be encountered in attempting to transmit the 5.00 mw at the source voltage of 4.50 kv?

In a game of pool, ball a is moving with a velocity v0 of magnitude v0 = 15 ft/s when it strikes balls b and c, which are at rest and aligned as shown. knowing that after the collision the three balls move in the directions indicated and assuming frictionless surfaces and perfectly elastic impact (that is, conservation of energy), determine the magnitudes of the velocities va, vb, and vc.
