A 0.900-V potential difference is maintained across a 1.50-m length of tungsten

Question

A 0.900-V potential difference is maintained across a 1.50-m length of tungsten wire that has a cross-sectional area of 0.600 x 10* nr. What is the current in the wire? Four point charges are located at the comers of a square as shown. Each edge of the square has a length of 2a. The magnitude of the electric field a point P at the square's center is Given four particles entering magnetic fields, as shown, what is the direction of the initial deflection for each particle? The figure shows the motion of electrons in a wire which is near the N pole of a magnet. The wire will be pushed: a) toward the magnet, away from the magnet, c) downwards, e) along its length. A long straight w ire carries a current I in the +z direction and this current produces a magnetic field. A proton moves along the y-axis w ith a speed v. The direction of the magnetic force on the proton is:

Explanation / Answer

Q1. no options are available

resistance = 5.6 x 10^-8 x 1.5/0.6 x10^-6 = 0.14 ohm

current in the wire = potential difference/resistance= 0.9/0.14=6.428 A
