Head circumference of 3 year old?
Use a Caterpillar!
what is the average head circumference of a 5 year old boy
Mercury and Venus have shorter years than a year on Earth. This is because they are closer to the sun and the circumference of their orbits is smaller than that of Earth's. Mercury and Venus
what is considered to be the normal (average) head circumference of a 5.5 year old boy?
It might actually be a really good idea to move the Earth farther away from the sun, giving the Earth a larger orbital circumference and a longer year. The Earth would also receive less sunlight, and therefore it would be less susceptible to overheating, which is an issue of great concern at the present time. However, we do not have any technology that is capable of altering the Earth's orbit. It would be extremely difficult to do, and very likely, we will never do such a thing, however useful it might be.

To calculate this speed, you need some more numbers, not just the distance from Earth to Sun. You need to know:* The gravitational constant * The distance from Earth to Sun * The mass of the Sun You DON'T need the mass of the Earth. Assume any mass; you can just call the mass of the Earth "m". Then calculate an expression for the gravitational attraction between Earth and Sun. Divide by the mass of the Earth, and you get a centripetal acceleration. Assuming a circular orbit for simplicity, the centripetal acceleration must be just this force. Use the formula for the centripetal acceleration along a circle (a = v squared / radius). (Don't forget to convert the distance from Earth to Sun, to meters!) Solve for "v".
The Earth makes a full turn around the sun once every year, knowing that and the circumference of the orbit you can calculcate the speed of earth which is approximately: distance / time = 30 km/s
the average waist circumference is about 25-30 inches or about 60 inches
The "year", in this case, refers to how long the planet takes to orbit the Sun. Uranus is farther away from the Sun; as a result, its orbit has a larger circumference AND it moves more slowly.
Sirius is a star, so it doesn't have an orbit like the planets do. Thus, you can't calculate a year for Sirius. All you can do is estimate its age in Earth years.
I know that a revolution on saturn is 29.5 Earth years so there would be about 10,767.5 Earth days but I didnt calculate leap years and other things like that but... I hope this helped! :)
Only Earth has an Earth year....
As Pluto is so far out in comparison to a Earth to the Sun. It takes a much longer time to get around the sun so its year are much longer. You can work out the length of a Plutonium year by using (G*mass of the sun)/radius form the sun to Pluto= the speed of Pluto squared. Which is 6.67x10^-11*2.00x10^30/5.9x10^12= 5165.27 ms-1 so then we can work out the circumference of the orbit find out how long it takes. the circumference is 3. 7x10^13 so t=3.7x10^13/5165.27=7163226705 seconds or 82907.7 days which is equivalent to 227 Earth years. I hope this helps
One Earth year is one Earth year everywhere.
One Earth year is one Earth year, whether experienced on Earth or on Jupiter.One Jovian year is 11.86 Earth years, so one Earth year is 0.084 Jovian years.
1 Earth year is Earth 365 days normally, or 366 Earth days for a leap year.
1 Saturn year = 29.7 Earth years 1 Earth year = 0.0337 Saturn year
There will not be a 53 week year. The way the earth rotates and revolves means that there will only be 365 days in a year, except leap years, when there are 366. However, this still fits a 52 week cycle.
The year on year change is the later year minus the previous year.
