Acar moving with an initial speed v collides with a second stationary car that is 46.7 percent as massive. after the collision the first car moves in the same direction as before with a speed that is 31.8 percent of the original speed. calculate the final speed of the second car. give your answer in units of the initial speed (i. e. as a fraction of v).

absorption lines are where light has been absorbed by the atom thus you see a dip in the spectrum whereas.

emission spectra have spikes in the spectra due to atoms releasing photons at those wavelengths.

explanation:

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.
