a ball hits a wall horizontally at 8 m/s it rebounds horizontally at m/s. the ball is in contact with the wall for 0.02 s. what is the acceleration of the ball?

The particles of the gas inside the ball heats up, bouncing off each other and spreading farther apart.hope my answer has you : )

That big glowy thing in the sky is called the sun

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.
