12.3 newtons third law of motion and momentum ws ignore what I already wrote down
on the backside because I have no idea if its correct or not haha. our teacher did not explain it at all so I have no idea what I am doing. ​

He can play two games. 13/4=3.253.25*2=6.5

The sample with the lowest specific heat capacity will have the greatest temperature increase. in this case, it would be platinum.

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.
