The image below shows a single toy car rolling down a ramp. What observable feature(s) would you expect to be present if kinetic energy increases as the car rolls down the incline? multiple choice A. The toy car's speed would stay the same as it moved down the ramp.

B. The temperature of the car would decrease.

C. The toy car's speed would increase as it moved down the ramp.

D. Sound from the movement would be produced.

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.
