Megan was doing time trials on her bike around a 400 meter horizontal track. compare the forward force on the bike with the backward force when megan was travelling at a constant speed. select the correct answer

The third hammer 8 pounds

The objects are acted upon by only one force. gravity. mass times the acceleration of gravity (-9.81meters/second squared).

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.
