The first factor to consider is a sidereal day, which is how long it takes Earth to complete a full rotation based on fixed stars. Since the orbital motion of our planet makes the Sun appear to move eastward relative to the stars, it has to rotate 361 degrees rather than just 360 degre...
Instead, you use its orbital motion. From Newton's version of Kepler's Third Law of Planetary Motion, the orbital speed of an object in circular orbit and a little algebra, you can derive an equation to calculate the amount of mass (Mr) that lies within any circular orbit with a radius...
The second factor to consider is that the Earth's orbital speed varies, which is whydays are longer and shorterthroughout the year. The planet moves fastest in early January during perihelion, which is its closest point to the Sun, and moves slowest in early July during aphelion, which is ...
To calculate location, a GPS device must be able to read the signal from at least four satellites. Each satellite in the network circles the earth twice a day, and each satellite sends a unique signal, orbital parameters and time. At any given moment, a GPS device can read the signals ...
Once the circumference (the distance Earth travels around the sun in one orbit) is calculated, its orbital speed can be determined. The solar system, which includes our sun and all of the objects that orbit it, is also moving; it's located within the Milky Way, which orbits around the...
which then lead to a new round of changing magnetic fields. The fields leapfrog over each other and can even travel through empty space. When Maxwell went to calculate the speed of these electromagnetic waves, he was surprised to see the speed of light pop out – the first theoretical calcul...

How do you calculate an astronomical unit? What is a light year used to measure? How many yards in a astronomical unit? How many square kilometers is an astronomical unit? What is one astronomical unit? One astronomical unit (AU) averages about how many meters?
(35,786 kilometers) above Earth, the satellite must orbit at a speed of about 7,000 mph (11,300 kph). That orbital speed and distance permit the satellite to make one revolution in 24 hours. Since Earth also rotates once in 24 hours, a satellite at 22,223 miles altitude stays in a...
Calculate the degrees of freedom for each of the independent samples. Degrees of freedom is usually represented by "n-1" or your sample size minus one. Write the degrees of freedom calculation in the summary statistics section. Step 3
