Awheel rotates with a constant angular speed ω. which one of the following is true concerning the angular acceleration α of the wheel, the tangential acceleration at of a point on the rim of the wheel, and the centripetal acceleration ac of a point on the rim?

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.

//(b) both involve the use of levers;

Imma say go with a (:
