An 800 kg car and a 1,600 kg truck move toward one another, both traveling at 15 m/s. In what direction will the two vehicles move after they collide? Show your calculations to prove your answer.

yup its correct its: c) b b

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.

if the person is shown to have +90n, then ans is -10n.

if the person is shown to have -90n, then ans is +10n.
