Hannah has information about an object in circular orbit around earth.

mearth = 6.0 × 1024 kg

g = 6.67 × 10–11

what additional information does hannah need in order to calculate the tangential speed of the orbiting object?

the mass of the orbiting object
the distance of the orbiting object to earth
the orbital period of earth
the radius of earth

The distance of the orbiting object to Earth will give Hannah the radius which she needs.

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.
