A block of ice is sliding across a frozen pond at a constant velocity. Use Newton’s 1st Law to decide whether or not the block of ice is experiencing a net force

Along, straight wire with 3.0 a current flowing through it produces magnetic field strength 1.0 t at its surface. if the wire has a radius r, where within the wire is the field strength equal to 36.0% of the field strength at the surface of the wire? assume that the current density is uniform throughout the wire

Aballet student who learns with the of his instructor is demonstrating learning.

Use the right-hand rule for magnetic force to determine the charge on the moving particle. this is a charge.
