Along, straight wire (radius = 2.0 mm) carries a current of 2.0 a distributed uniformly over a cross section perpendicular to the axis of the wire. what is the magnitude of the magnetic field at a distance of 1.0 mm from the axis of the wire?

If you were on a jury, do you think you would expect individual characteristics in the evidence? why or why not? what effects might it have if individuals expect to have individuals characteristics presented? this question is for forensic science

Which situation will produce the greatest change of momentum

Two steel balls, each of mass m, are welded to a light rod of length l and negligible mass and are initially at rest on a smooth horizontal surface. a horizontal force of magnitude f is suddenly applied to the rod as shown. determine (a) the instantaneous acceleration a of the mass center g and (b) the corresponding rate at which the angular velocity of the assembly about g is changing with time.
