PRACTICE IT Use the worked example above to help you solve this problem. Two wires, each having a weight per unit length of 1.14 x 10-4 N/m, are parallel with one directly above the other. Assume that the wires carry currents that are equal in magnitude and opposite in direction. The wires are 0.16 m apart, and the sum of the magnetic force and gravitational force on the upper wire is zero. Find the...

Assume you have the choice of two algorithms for the same problem, (a) One that reduces a problem of size n in O(n) time to two sub-problems of size in, or (b ) One that solves the problem without any recursion in time O(n2) Which algorithm is faster? Show that if f(n) f(½n) + O(log(n)), then f(n) = O((log n) 4. Write code for a function that takes a nonempty search tree of the form discussed in the class,...

1. Two long, straight parallel electrical wires are mounted on poles such that one wire is mounted 3.0 cm higher than the other. There is a current of 100 A in the same direction in each wire. Each wire has a mass of 0.042 kg per meter of length. A. Calculate the magnitude of the force per unit length acting on the lower wire due to the magnetic field created by the upper wire. Also clearly indicate the direction of...

Question 4 1.2 pts 4) Two long ſinfinite) wires are placed in the x-y plane parallel to one another. One is placed on the x axis and the current in that wire is 44 amps running in the +x direction. The other wire is placed at y = +3.8 meters (3.8 meters "above" the first wire, in the x-y plane). The second wire has a force per unit length of 40 x 10-7 N/m in...
