A 0.300 kg air hockey puck moving 3.33 m/s northwest hits an identical puck moving south at 1.87 m/s. The first puck ends up going 2.10 m/s west. What is the y-component of the final velocity of the second puck?

Magma  is composed of molten rock and is  stored  in the earth's crust. lava is  magma  that reaches the surface of our planet through a volcano vent.

Answerthe energy required is 1.60 × 10⁻¹⁸ j, to three significant figures.explanationwe define electric potential as the ratio electric potential energy to the charge,    then the following gives us the potential difference,      the formula  may be on your formula sheet.the change in electric potential energy would be the energy that would needed to move it from point a to point b. solving for that, we get    using q = 8.00  × 10⁻¹⁹ c and  δv = 2.00 v, we get    the energy required is 1.60 × 10⁻¹⁸ j, to three significant figures.

Lexy is correct because angle r is between the incident wave,  n  = 0, and a diffracted wave.
