Which scenario could be represented by the motion map? a car speeds up to merge onto the freeway and then continues at a constant velocity. a car speeds up to pass a truck, then slows down to a constant velocity. a car slows to stop at a stop sign. once traffic is clear, the car speeds up. a car slows to makes a u-turn, then continues in the opposite direction.

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.
