A ball is thrown straight up from height H while a second is thrown straight down. Neglect air resistance. After the balls have been released
(a) the one thrown up has the greater acceleration.
(b) the one thrown down has the greater acceleration.
(c) the accelerations are the same.
(d) neither ball accelerates after it has been released.

Sound energy is produced when an object vibrates. examples are 1- a balloon popping2-a whistle3- a waterfall

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.
