A rectangular channel of 20 ft width has a depth of 4 ft and velocity of 60 ft/sec. Deter- mine (a) whether a jump can form in the channel, (b) the downstream depth needed to form the jump, and (c) the loss of energy through the jump.

Aquarterback pedals 3.3meters southward and then run 5.7meters northward. whats the distance ? and whats the displacement?

Two 1.20-m nonconducting wires meet at a right angle. one segment carries + 2.50 µc of charge distributed uniformly along its length, and the other carries - 2.50 µc distributed uniformly along it, as shown in fig. 21.50. ( a. find the magnitude and direction of the electric field these wires produce at point p, which is 60.0 cm from each wire. ( b. if an electron is released at p, what are the magnitude and direction of the net force that these wires exert on it?
