Ever magnitude goes up by a multiple of 10.
So lets say this..
1-10
2-100
3-1000
4-10000
5-100000
6-1000000
7-10000000
So, a 5 magnitude earthquake is 100 times more powerful then a 3 magnitude.
A stars brightness depends on two factors; its distance from us and its actual brightness (absolute magnitude). The actual brightness of a star depends on various factors, such as its mass, its temperature and its age.Consider two stars of the same actual brightness (absolute magnitude) - if one of them is much closer, then is will be brighter than the further one. It will appear brighter, even though it would be the same side by side - it can be said to be apparently brighter (higher apparent magnitude) due to its distance.A:They appear bigger and brighter because they really are bigger and brighter, but even if they are not bigger and brighter it could be because they are closer.
Distance
No, the Earth is much bigger.
Yes, in "absolute magnitude", Mizar is much brighter than the Sun.
Betelgeuse is much bigger than the Sun.
The amplitude of a magnitude 8 earthquake is 100 times larger than a magnitude 6 earthquake.
The Richter magnitude scale is a base-10 logarithmic scale of the shaking amplitude. This means that a difference of 1 in the scale is equivalent to a 10-fold increase in amplitude. So the difference in amplitude between a mag 8 and a mag 4 earthquake is 104.
The magnitude of -13 is bigger than the magnitude of 12, but -13 is less than 12.
It is 794 times bigger on a seismic scale.
Each increase by one magnitude corresponds to a release of energy 31.6 times that released by the lesser earthquake.Since 7 is 3 magnitudes higher than 4, the magnitude 4 earthquake has roughly 1/31554th the energy of the magnitude 7.Each increase by one magnitude corresponds to a release of shaking amplitude 10 times that released by the lesser earthquake.Since 7 is 3 magnitudes higher than 4, the magnitude 4 earthquake has 1/1000th the shaking amplitude of the magnitude 7.The amount of energy changes much more rapidly with magnitude than the amount of shaking amplitude. This is a commonly made error.
An earthquake with a magnitude of 5.0 has a shaking amplitude 10 times that of an earthquake with a 4.0 magnitude.
-5 has a larger magnitude. It depends on your definition of "bigger". If you say bigger means "has a larger magnitude" then -5 is bigger than -3. If you say that if two numbers A and B are in the set of integers from negative infinity to positive infinity, then A is bigger than B if A is closer to positive infinity than B, this means that -3 is bigger than -5.
See the related link for answer. A 5 is 32 kilotons of TNT, a 6 is 1 megaton of TNT.
Every change of 1 on the Richter scale increases the amplitude of the measured seismic waves of the earthquake by a factor of 10 and the energy released scales with the shaking amplitude based on the following: Change in energy released = (10^Md)^(3/2) Where Md = difference in magnitude between two earthquakes (in the example above this is 3.0) Therefore a magnitude 6.0 earthquake releases (10^3.0)^(3/2) = 31,622 times more nergy than a magnitude 3.0 earthquake and has seismic waves with 1000 times larger amplitude.
My understanding of the magnitudes of earthquakes is that each decimal point is equal to a magnitude of strength 10x more than the previous number. Example would be that a 4.2 earthquake is 10x stronger than a 4.1 earthquake. Therefore, a magnitude 8.5 EQ is 100x stronger than a 7.5 EQ.

A coulomb is bigger. Please also note that a coulomb is defined as a POSITIVE charge, while an electron has a NEGATIVE charge. Anyway, the magnitude of a coulomb is much bigger than that of an electron.
