Asquare loop of wire lies in the x, y plane with opposite corners at (0, 0) and (a, a), and is situated in a steady magnetic field b = b0(yz xˆ + xz yˆ + xy zˆ). if the loop moves with velocity v = vxˆ, calculate the motional emf e = h (v×b)· dl in terms of a, b0, and v. what is the direction of current flow in the loop?

Two thin 80.0- cm rods are oriented at right angles to each other. each rod has one end at the origin of the coordinates, and one of them extends along the x- axis while the other extends along the yaxis. the rod along the x- axis carries a charge of - 15.0 μ c distributed uniformly along its length, and the other rod carries 15.0 μ c uniformly over its length. find the magnitude and direction of the net electrical force that these two rods exert on an electron located at the point (40.0 cm, 40.0 cm). (e

The necleus of an atom is made up of what subatomic particles?

A1-lb collar is attached to a spring and slides without friction along a circular rod in a vertical plane. the spring has an undeformed length of 5 in. and a constant k =25 lb/ft. knowing that the collar is released from being held at a determine, the speed of the collar and the normal force between the collar and the rod as the collar passes through b.
