I believe that B is the answer.
The correct answer is (a.) diffuse. The reflection of light waves from a rough surface is called DIFFUSE reflection. This type of reflection reflects light diffusely mostly from a surface that is a non-absorbing material such as plaster and polycrystalline.
Answer:
1 mole of H2O is 18 grams (2 g H + 16 g Oxygen)
36 / 18 = 2
So 2 moles = 2 * 6.02E23 = 12.04E23 = 1.204E24
Explanation:
At the top of the the ball's trajectory, there is only the horizontal component of the initial velocity, which is so the kinetic energy of the ball at this point is
