How does the lighter material of the bamboo affect the force created by the rider on the bike?

It's because 3 if it was 10 it wouldn't look right do it goes up to 4d

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.

Lexy is correct because angle r is between the incident wave,  n  = 0, and a diffracted wave.
