a) Compute the resistance of an automobile jumper cable. (Suppose that the length of the jumper cables is 2.5 m. Also suppose the wires are made of copper and have a cross-sectional area of 10 mm2.)
b) A current is required to start a typical car. What is the potential drop that occurs across the jumper cable? (Take the starting current to be 93 A.)
c) How much power is dissipated in the jumper cable when it carries that current?
question 1 why does the amplitude of the vibration of the lrc circuit change with frequency?question 2 when does the
A movig particle encounters an external electric field that decreases its kinetic energy from 9960 eV to 7700 eV as the particle moves from position A to position B. Determine the charge of the particle

The combined mass of the professor and the chair is 90-kg. He is pushed 2.60-m along the incline by a group of students who together exert a constant horizontal force of 600-N. The professor speed at the bottom of the ramp is 1.75m/s. use the work..
Two current-carrying wires are exactly parallel to one another and both carry 3.5 A of current, What is the direction of the magnetic force caused by wire 2 on wire 1
On a frictionless, horizontal air table, puck A (with mass 0.25 kg) is moving toward puck B (with mass 0.350 kg), that is initially at rest. After the collision, puck A has a velocity of 0.120 m/s to the left, and puck B has velocity 0.620 m/s to the..
