One seismogragh can determine?
The distance to the epicentre of an earthquake and it's magnitude.
What three factors determine the magnitude of star?
The apparent magnitude of a star is dependent on the star's size, temperature and distance from where it is observed. An absolute magnitude is determined by the same three factors, but the distance is fixed at 10 parsecs.
What is the suns absolute magnitude from earth?
You cannot ask for an absolute magnitude and specify the distance, as the absolute magnitude is derived from a set distance of 32.616 light years.At that distance, the absolute magnitude of the Sun is +4.83From Earth the apparent magnitude -26.74
What are three factors that determine the apparent magnitude of a star?
Its real (absolute) magnitude; its distance from Earth; the amount of light that's absorbed by matter between the star and us (extinction); distortions due to gravitational lensing.
The distance from the earth to a star that has identical apparent and absolute magnitudes is?
The standard distance used for evaluating absolute magnitude is 10 parsec.The standard distance used for evaluating absolute magnitude is 10 parsec.The standard distance used for evaluating absolute magnitude is 10 parsec.The standard distance used for evaluating absolute magnitude is 10 parsec.
What terms takes into consideration the brightness of a star but ignores the differences that distance can make?
"Apparent magnitude" is the star's brightness after the effects of distance. "Absolute magnitude" is the star's brightness at a standard distance.
What 2 factors determine a star's apparent magnitude?
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.
How does apparent magnitude of a star differ from absolute magnitude?
Apparent magnitude is the brightness as observed from earth, while absolute magnitude is the brightness of a star at a set distance. The apparent magnitude considers the stars actual brightness as well as it's distance from us, but absolute magnitude takes the distance factor out so that star brightnesses can be directly compared.
What distance is the absolute magnitude and the apparent magnitude of a star would be equal if the star is seen at?
The standard distance is 10 parsecs. At this distance the star's apparent magnitude equals its absolute magnitude. A star 100 parsecs away has an absolute magnitude 5 magnitudes brighter than its apparent magnitude. 1 parsec is 3.26 light-years.
What is the definition of absolute magnitude?
The absolute magnitude is the magnitude (brightness) an object would have at a standard distance - how bright would it look at a standard distance. For a star or galaxy, the standard distance of 10 parsecs is commonly used.
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.
Is distance a vector or scalar quantity?
Distance is a sclar quantity. A scalar quantity is a magnitude only. A vector has magnitude and direction. Distance AND direction is a vector quantity.
