In the Bohr model of the hydrogen atom, an electron in the lowest energy state moves around the nucleus at a speed of 2.19 × 10 6 m/s at a distance of 0.529 × 10 − 10 m from the nucleus. (a) What is the electric potential due to the hydrogen nucleus at this distance? (b) How much energy is required to ionize a hydrogen atom, whose electron is in this lowest energy state? Assume the electric potential goes to zero as r → [infinity] .

explanation:

as the height from which the ruler was dropped increased, the speed of the ruler at ryan's hand increased.

adding a(n) to an electric circuit would increase the magnetic field around a wire;

b. solenoid

a solenoid is a type of electromagnet whose purpose is to generate a controlled magnetic field.

if the purpose of the solenoid is instead to impede changes in the electric current, a solenoid can be more specifically classified as an inductor rather than an electromagnet.

can somebody give me the answer so i can graduate

earth's neighboring galaxy, the andromeda galaxy, is a distance of 2.54×107 light-years from earth. if the lifetime of a human is taken to be 70.0 years, a spaceship would need to achieve some minimum speed min to deliver a living human being to this galaxy.
