I would say B. Hope this helps Plz give a thx
Answer:
I think is 3 I am not sure
The total kinetic energy before the collision is not equal to the total kinetic energy after the collision. A portion of the kinetic energy is converted to other forms of energy such as sound energy and thermal energy. A collision in which total system kinetic energy is not conserved is known as an inelastic collision.
Answer:
The answer is 2 because the formula is
wavelength=speed/frequency
