A 4000-kg car traveling with a speed of 25m/s skids to a stop on a flat/level surface. The car experiences a 3000N force of friction. Determine the stopping distance of the car.

If an electric circuit is not grounded it is best to reach out and touch it to provide the ground a.true or b.false

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?
