Neptune has 13 known moons and an orbital period of about 60190 Earth days.
There is technically a 9i orbital, but no atom in the ground state has any electrons in this orbital (in fact, no known element has any electrons in even the 8s orbital, and there are quite a few energy levels between that and 9i). In an excited state ... sure, it could happen.
Two electrons can occupy the same space orbital in an atom if they have different spins. This is known as Hund's Rule.
There isn't enough information to make a calculation. If the mass is known and the radius is known, we can see that a steel plate with the given mass and radius will be thinner than a plastic plate with the same mass and radius. And a uranium plate will be thinner than the steel one if it has the same mass and radius. Without the density of the material or a knowledge of what it is (so we can look up its density), we're dead in the water. We can't solve it.
Electrons move between different energy levels in an atom. When electrons are in the lowest orbital, otherwise known as the ground state, they eventually progress into the highest orbital, also known as the excited state. When electrons move from the excited state back to the lowest orbital, they emit energy in the form of light that varies in colors, depending on the element. Some of these forms of light may not always be visible to the naked eye.
The formula, when the radius is known, is: A = PI(r)2 A circle with a radius of 450 mm has an area of 636,172.51 square mm.
First divide by (2 x pi) to obtain the radius. Then calculate the area with the well-known formula for the area of a circle: A = pi x radius2.First divide by (2 x pi) to obtain the radius.

Given is a circle. Not known is its area A. Not known is its radius r. Not known is its diameter d. You want to calculate its circumference C. Impossible. It cannot be calculated. The only other way is to measure it with a tape measure.
39 decimal places.
A planet's orbital period is also known as its year.
the perimeter of a circle, also known as the circumference, is calculated by diameter multiplied by pi. Alternatively : 2 x radius x pi
r = known radius x = known arc length --------------------------- C (circumference of circle) = 2 * PI * r A (angle of chord in degrees) = x / C * 360 L (length of chord) = r * sin(A/2) * 2
the volume of a cylinder is V = pi*r^2 * l (where v is volume r is radius and l is length) so you would do this equation to find it:length = V / (pi * r^2).
The answer depends on what information about the circle is given: area, radius, length and angle of arc, area and angle of sector, etc. In each case, there is a different way to calculate the diameter but, since there is no information on what is known, it is not possible to answer the question.
not known
At lower speed, the object will fall back on the ground. Since, earth is curved, if the object has enought speed, the object can try to fall beyond the curvature of the earth. Thus, it will not hit ground at all. The speed to achieve it is around 8 km/s. If the object is faster than 11.4 km/s then the object will never return. It is called escape velocity.
From the centre of a circle to the outside edge is known as the radius.
