A 3.8 x 10^4-kg space probe is traveling at a speed of 15000 m/s through deep space. Retrorockets are fired along the line of motion to reduce the probe's speed. The retrorockets generate a force of 1.5 x 10^4 N over a distance of 3500 km. What is the final speed of the probe?

Letter a, because when there are unlike charges they will always attract to each other.

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.

Iwould say the answer is d

Iwould think it is temperature, silica, oxides (gases)
