A 8.00-kg toy car, moving at 6.0 m/s in the - x direction, collides head-on with a 12.00-kg toy car moving at 5.0 m/s in the opposite direction. If the cars stick together after the collision, what % of momentum and kinetic energy is lost in the collision ?

adding a(n) to an electric circuit would increase the magnetic field around a wire;

b. solenoid

a solenoid is a type of electromagnet whose purpose is to generate a controlled magnetic field.

if the purpose of the solenoid is instead to impede changes in the electric current, a solenoid can be more specifically classified as an inductor rather than an electromagnet.

friction

they us to move forward and backwards
