A wall and a fence meet at right angles, with the wall running north-south. Two spots are marked at a distance 1 meter east of the wall; they are 3 and 6 meters north of the fence. What is the length of the shortest path from one spot to the other, provided the path meets the wall and the fence (possibly at two different points)?

Two straight parallel wires, running north/south are separated by 12 cm and carry currents of 4 A in the same direction (north). Find the magnitude and direction of the magnetic field at a point midway between the wires. Now find the magnetic field 6 cm east of the "easternmost" wire. Also, calculate the force of one wire on the other. Is it attractive or repulsive?

2. Two wires are running parallel with respect to each other in space from south to north, and are separated by a distance of 10 cm. They both carry currents from south to north. The wire on the left (wire 1) carries a current of 11 =10 A, and the wire on the right (wire 2) carries a current of I2 =20 A. Answer the following: (6 marks total) a. Find the direction and magnitude of the force acting on...

A 110 kg running back carries the ball south at 8 m/s. A 130 kg linebacker runs to make the tackle going north at 5 m/s. In their collision, the linebacker wraps his arms around the runner and makes it an inelastic collision. How fast are they moving right after the collision (before they fall to the ground)? 3. A 2000 kg SUV traveling at 7 m/s south runs into the rear end of an 800 kg compact car sitting...

Having a rough time getting started with the constructors and the display function of this class, any advice/assitance is appreciated! Task You will write a class called Grid, and test it with a couple of programs. A Grid object will be made up of a grid of positions, numbered with rows and columns. Row and column numbering start at 0, at the top left corner of the grid. A grid object also has a "mover", which can move around to...
