How big is regulus?
Regulus is the brightest star in the constellation Leo.It is about 4 times larger than our own Sun with an estimated radius of between 3.15 and 4.15 that of our Sun.

Stars are now classified by how?
The Hertzsprung-Russell ishowing the relationship between the stars' absolute magnitudes or luminosities. The sequence is Obafgkmrns. Each letter representing a classification of type.
If star A is third magnitude and star B is fifth magnitude which is brighter and by what factor?
A 3rd magnitude star is brighter than a 5th magnitude star by a factor of 6.25.Each integer difference of magnitude represents a change in apparent brightness of 2.5 times. Hence, a 3rd magnitude star is 2.5 x 2.5 = 6.25 times brighter than a 5th magnitude star.(check related links)

What is the magnitude of the resultant force when forces of magnitude are combined?
-- When forces of unequal magnitude are added, the magnitude of the sum can be anything between the difference and sum of the individual magnitudes, depending on the angle between them. -- When forces of equal magnitude are added, the magnitude of the sum can be anything between zero and double the individual magnitudes, depending on the angle between them.
The sum of two vectors is a minimum when the angle between them is what?
180 degrees. Then the sum of the two vectors has a magnitude equal to the difference of their individual magnitudes.
Can two vectors having different magnitude be combined to give a zero resultantis it possible for three vectors?
-- The minimum magnitude that can result from the combination of two vectors is the difference between their magnitudes. If their magnitudes are different, then they can't combine to produce zero. -- But three or more vectors with different magnitudes can combine to produce a zero magnitude.
What is the difference between shallow focus earthquakes and deep focus earthquakes?
Shallow focus earthquakes occur at depths of 70 km with magnitudes ranging from 1-5. Deep focus earthquakes occur at depths from 300-700 km and magnitudes from 6-10.
What is the angle between two vectors if their sum is to be maximum?
The resultant vector has maximum magnitude if the vectors act in concert. That is, if the angle between them is 0 radians (or degrees). The magnitude of the resultant is the sum of the magnitudes of the vectors.For two vectors, the resultant is a minimum if the vectors act in opposition, that is the angle between them is pi radians (180 degrees). In this case the resultant has a magnitude that is equal to the difference between the two vectors' magnitudes, and it acts in the direction of the larger vector.At all other angles, the resultant vector has intermediate magnitudes.
How big is regulus?
Regulus is the brightest star in the constellation Leo.It is about 4 times larger than our own Sun with an estimated radius of between 3.15 and 4.15 that of our Sun.
Where is the star regulus Near the sun or in between sun and earth etc?
Regulus is about 77 light years distant from earth.There are no other stars between the sun and earth.The nearest star to earth is about 278,000 timesas far from us as the sun is.Regulus is about 17 times as far from us as that star is.
What is the difference between a twelfth magnitude and fifteenth magnitude star?
Three magnitudes, and the 12th magnitude star is the brighter star. Mathematically it means the brightness difference is about: 2.512 x 2.512 x 2.512. That's about 15.85 times brighter.
How do you take dot product of two vectors?
Multiply the product of their magnitudes by the cosine of the angle between them.
What is peak to peak?
Peak to Peak is the most positive peak to the negative peak value. Or find any peak value and multiply by 2.
Statment between the magnitude of a earthquake and how often earthquakes of the magnitude occur?
One statement you could write is that "Earthquakes of higher magnitudes are much rarer than those of lower magnitudes". The magnitude of earthquakes is a logarithmic scale, so a magnitude of 8 is TEN TIMES more powerful than a magnitude 7. This is why earthquakes of higher magnitudes are so much rarer than those of lower magnitudes.
What are the rules for adding a positive and negative integer?
The magnitude of the sum is the difference between the magnitudes of the two numbers. The sign of the sum is the sign of the number with the larger magnitude. (The "magnitude" of a number is just the size of the number without any sign.)
