What is the stars absolute magnitude?
A star's "absolute magnitude" is a measure of its absolute (or real) brightness. It is defined as the "apparent magnitude" the star would have at a standard distance of 10 parsecs, which is equal to 32.6 light years.
What is the relationship between the absolute magnitude and luminosity of a celestial object?
The absolute magnitude of a celestial object is a measure of its brightness as seen from a standard distance, while luminosity is the total amount of energy a celestial object emits per unit time. The relationship between absolute magnitude and luminosity is that a higher absolute magnitude corresponds to a lower luminosity, and vice versa. In other words, the absolute magnitude and luminosity of a celestial object are inversely related.
What can be said about the absolute magnitude of two equal-sized stars whos colors are blue-voilet and orange-red?
Absolute magnitude refers to a measure of the real brightness of a star. In terms of absolute magnitude, a blue-violet star is classified as bright, while an orange-red star is classified as faint.
What is the relationship between star brightness star temperature?
The Hertzsprung-Russell diagram shows absolute magnitute or brightness against it's colour (which is an indication of temperature) . This shows the main sequence, which describes the typical life of a star.
Would you need half a million full moons to equal the brightness of the sun?
The apparent magnitude (AM) [See Link] is a measure of its brightness as seen by an observer on Earth, in the absence of the atmosphere. The brighter the object appears, the lower the value of its magnitude. The Sun has an AM of -26.73 whereas a full Moon has an AM of -12.6. The scale is logarithmic: the relative brightness of two objects is determined by the difference of their magnitudes. Pogson's Ratio was suggested in 1856 so that each decrease in magnitude represented a decrease in brightness equal to the fifth-root of 100 (or about 2.512) So, the difference in magnitude is (-12.6) - (-26.73) giving 14.13 Thus 2.51214.13 = 449,032. Close enough to half a million.
The true brightness of a star is called its BLANK magnitude?
The scale of star brightness is the 'magnitude'. The definition of the magnitude is: A change of six magnitudes equals a factor of 100. So one magnitude change is a factor equal to the 6th root of 100 = about 2.15443 (rounded)
What is the stars absolute magnitude?
A star's "absolute magnitude" is a measure of its absolute (or real) brightness. It is defined as the "apparent magnitude" the star would have at a standard distance of 10 parsecs, which is equal to 32.6 light years.
What numbers have equal absolute values?
A positive and negative number with the same magnitude (value) will have their absolute values equal.
When does distance traveled equal the magnitude of displacement vector?
Distance traveled is equal to the magnitude of the displacement vector when the motion is in a straight line.
When is the magnitude of displacement equal to the distance?
The magnitude of displacement is equal to distance when an object moves in a straight line without changing direction. This occurs when displacement and distance have the same direction.
What is the relation between magnitude of distance and displacement?
-- Distance is a scalar quantity, whereas displacement is a vector. -- Distance is the integral of magnitude of displacement. -- Magnitude of displacement is always less than or equal to distance. -- The two quantities are equal when the motion is in a straight line.
Under what condition the distance and displacement are equal?
The magnitude of displacement is equal to distance traveled when motion is in a straight line.
When is speed equal to magnitude of velocity?
Speed is equal to the magnitude of velocity almost always. Speed is total distance / total time no matter which way the distance goes. Velocity is the distance from a starting point divided by total time.
Is Distance is always less than or equal to the magnitude of the displacement true?
That depends on what distance you are measuring.
What conditions the distance and displacement between two points will be equal?
Answer: The magnitude of displacement is equal to distance traveled when motion is in a straight line
Is the magnitude of displacement greater than or equal to the magnitude of the distance traveled?
In general, the magnitude of displacement can be either greater than, equal to, or less than the magnitude of the distance traveled. This depends on the specific path taken by the object. If the path involves any changes in direction, the displacement can be shorter than the distance traveled. If the object moves in a straight line, the displacement and distance traveled will be equal.
What is the relationship between the absolute magnitude and luminosity of a celestial object?
The absolute magnitude of a celestial object is a measure of its brightness as seen from a standard distance, while luminosity is the total amount of energy a celestial object emits per unit time. The relationship between absolute magnitude and luminosity is that a higher absolute magnitude corresponds to a lower luminosity, and vice versa. In other words, the absolute magnitude and luminosity of a celestial object are inversely related.
