Two long straight parallel wires are 12cm apart. Wire A carries 1.5A current. Wire B's current is 4.0A in the same direction.
A) Determine the magnetic field magnitude due to wire A at the position of wire B.
B) Determine the magnetic field due to wire B at the position of wire A.
C) Are these two magnetic fields equal and opposite? Why or why not?
A dead tree is initially stationary and there is a 30.0-degree angle between the tree and the vertical. The roots finally give way and the tree topples to the ground (rotating on an axis that is parallel to the level ground and intersecting the ba..
Find out the critical angle theta_ce for e-waves in calcite. The index of refraction for light with electric field parallel to the optical axis (called extraordinary waves or e-waves) is 1.4864. The index of refraction for light with electric fiel..
A person driving her car at 57km/h approaches an intersection just as the traffic light turns yellow. She knows that yellow light lasts only 2.0 s before turning to red, and she is 30m away from the near side of the intersection.
Imagine that the cannon from Problem #1 is actually firing into a strong wind, What is the final velocity vector of the ball when it lands
The only force acting on a 2.7 kg canister that is moving in an xy plane has a magnitude of 2.7 N. The canister initially has a velocity of 3.0 m/s in the positive x direction, and some time later has a velocity of 7.4 m/s in the positive y direct..
A rock of mass 44 kg accidentally breaks loose from edge of a cliff and falls straight down. The magnitude of the air resistance that opposes its downward motion is 252 N. What is the magnitude of the acceleration of the rock?
In a women's 100-m race, accelerating uniformly, Laura takes 1.81 s and Healan 3.06 s to attain their maximum speeds, which they each maintain for the rest of the race.
What are the displacement and velocity of the point on the cord. What is the magnitude of the acceleration of one of the liners toward the other because of their mutual gravitational attraction.
A 15 g rifle bullet traveling 250 m/s buries itself in a 3.0 kg pendulum hanging on a 2.9 m long string, which makes the pendulum swing upward in an arc. Clarify the horizontal component of the pendulum's displacement.
At T = 0ºC and p = 1000mb, 1g of dry air receives during an isochoric process anamount of heat, what is the amount of heat absorbed
A 18.0 kg block is dragged over a rough, horizontal surface by a constant force of 77.6 N acting at an angle of 35? above the horizontal. The block is displaced 10.8 m, and the coefficient of kinetic friction is 0.149.
A 110 granite cube slides down a 45 degree frictionless ramp. At the bottom, just as it exits onto a horizontal table, it collides with a 235 steel cube at rest. How high above the table should the granite cube be released to give the steel cube a..
