Aconductor bent into a semicircle of total length 2.35 m is placed in a 2.0 t magnetic field perpendicular to the plane of the semicircle. what is the magnitude of the total force on the conductor if a 5.63 a current passes through it?

On a frictionless air track, a blue glider with mass 0.200 kg is moving to the right with a speed of 8.00 m/s. it strikes a red glider that has mass 0.600 kg and that is initially at rest. after the collision, the blue glider is moving to the left with a speed of 3.00 m/s.(a) what are the magnitude and direction of the velocity of the red glider after the collision? (b) is this collision elastic?
