Acar is driving toward a building at 15 mph. on the roof of the car, an insect is scurrying away from the building at 10 mph relative to the cars roof. to a person sitting in the building, what is the insects velocity

Electoral current force mechanical advantage if the wheel and axle is 2 n and the output force is 20 n

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.

Hi. i believe this is called a scientific  theory.cheers!
