Aplanet has an average distance to the sun of 0.66 au. in two or more complete sentences, explain how to calculate the orbital period of the planet and calculate it.

We can use the formula for orbital time period:

T² = (4π²/GM)a³; where T is in Earth years, a is distance from sun in AU, M is the solar mass (1 for the sun), G is the gravitational constant.

In the given units, 4π²/G = 1

T² = 0.66³

T = 0.536 Earth years = 195.71 Earth days

because the two particles have an equal charge, the charges will cancel out and give the atom an overall charge of 0. so, if at atom has 35 protons in the nucleus, we could expect it to have 35 electrons orbiting that nucleus.
