The height of the particle being bombarded, and the type being bombarded by electrons from the Sun.
The same factors that determine the force of gravity between ANY objects. (1) The masses involved, (2) the distance between the masses.
The Aurora borealis, or northern lights, can occur anytime it is dark and the sky is clear, usually between 9 pm and 2 am. However, the best time to see them is typically between 10 pm and 2 am. Timing can also vary based on the geomagnetic activity in the region.
There are three factors, actually. The star's size and temperature determine the absolute magnitude, or how bright the star really is. Those two factors can be considered as one - the star's absolute magnitude. The absolute magnitude combined with our distance from the star determines its apparent magnitude, or how bright the star appears to be from Earth. So, a big, hot, super bright star very far away may have the same apparent magnitude as a small, cool star that's fairly close to the Earth.
It's just like a factor tree, except the original number goes on the bottom and the factors go above it. All composite numbers can be expressed as unique products of prime numbers. This is accomplished by dividing the original number and its factors by prime numbers until all the factors are prime. A factor rainbow can help you visualize this. Follow the steps in order. Example: 210 7,5,3,2 (4.) Stop. All the factors are prime. 35,3,2 (3.) Divide by five. 105,2 (2.) Divide by three. 210 (1.) Divide by two. 2 x 3 x 5 x 7 = 210 That's the prime factorization of 210.
There isn't really a schedule of auroras; they happen when a stream of charged particles from the Sun interact with the Earth's magnetic field. Watch the website at spaceweather.com (see the link below) and look for "coronal mass ejections"; bright auroras often follow about 2 days later. But they sometimes are visible without any warning, because the Sun is CONSTANTLY sending out masses of charged particles. Both aurorae occur around the polar regions. The Aurora Australis appears around Antarctica and the Aurora Borealis appears around the Arctic. The Aurora Australis is only visible from the southern latitudes and has never been seen north of the 30 degree line of latitude. The aurora is associated with solar wind activity and is most prevalent at the peak of the eleven year sun spot cycles, and the three years afterwards. The best places to see an Aurora Australis in the Australasia region would be Tasmania or New Zealand, away from cities and other sources of artificial light pollution.
Time and distance
Factors: elasticity and shape of the object
The prime factors of 30 are: 2, 3, and 5.
The mass divided my the volume determine the density of an object
size, and shape
Mass and distance
density and gravitational pull
The two factors that determine the state of a substance are temperature and pressure. These factors influence whether a substance exists as a solid, liquid, or gas.
The two factors are the amount of mass an object has and the distance between the two objects.
