According to kepler's harmonic law, neptune would have a orbit around the sun than mercury.
slower
faster
equal

Slower

Explanation:

Kepler's harmonic law (also called Kepler's third law) states that:

"The cube of the radius of the orbit of a planet around the sun is proportional to the square of its period of revolution"

In formula, this can be written as

where

r is the radius of the orbit

T is the orbital period

const. is a constant number, which is the same for all the planets orbiting the sun

By looking at the equation, we can see that the further a planet from the sun, the larger its orbital period: this means that the further planet will have a slower orbit. In this problem, we have to compare Neptune and Mercury: since Neptune is further from the sun than Mercury, also its orbital period will be larger, and therefore Neptune would have a slower orbit around the Sun than Mercury.

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.

i had this question and the answer was 3.15 miles.
