Question1

A 1.10 m long straight wire section has a resistance R = 46.0 ohm and is linked, with conducting wire of negligible resistance, to a 3.0 V battery. The wire is positioned in a uniform magnetic field B directed perpendicular to that section of wire. Determine the magnitude of B when the force on the wire due to B has a magnitude of 0.250 N

Question2

The driver of a 1720 car travelling on a horizontal road at 118 rapidly applies the brakes. Because of a slippery pavement, the friction of the road on the tires of the car, which is what slows down car, is 24.0 of the weight of the car.
