A driver is on a highway that has provided an odometer test zone in which signs mark
every
kilometre for 25 km. He checks his
watch and sees that it is 1:16 P. M. when he
passes the 5.0 km marker. When he passes
the 25 km marker, his watch reads 1:31 P. M.
What was his speed for that section of the
test zone?

Hypothesis. why don’t you know this? i learned this stuff in like 5th grade

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.
