A star's real luminosity is proportional to the the square of its diameter, and more or less proportional to the fourth power of its absolute temperature.
The star's apparent luminosity is proportional to its real luminosity. It is also inversely proportional to the square of the distance.
What else can I help you with?
What three things affect the apparent magnitude of a star?
1: The size of the planet.2: The planet's distance from the Sun.3: The "albedo" of the planet (the percentage of the Sun's light it reflects).If you mean how bright the planet appears to us on Earth, then the distance from Earth is obviously very important.
What two factors affect how bright a star appears in the night sky?
Two factors that affect a star's apparent brightness are: 1.) The distance between the Earth and the star 2.) The absolute magnitude (the actual brightness) of the star Hope that helps :P
What three factors affect air temperature?
Three factors that affect air temperature are latitude (distance from the equator), altitude (elevation above sea level), and proximity to large bodies of water (oceans, lakes). These factors influence the amount of incoming solar radiation, the air's ability to retain heat, and the presence of maritime or continental climates which can affect temperature.
Will an earthquake get bigger if it is deeper?
No. Size does not necessarily affect the magnitude of an earthquake. In fact, a deep earthquake will have less of an effect on the surface than a shallow earthquake of the same magnitude.
Do catalysts affect temperature?
A catalyst affects the speed of a chemical reaction. If the chemical reaction gives off heat, the reaction may affect the temperature, but the catalyst by itself doesn't affect the temperature.
How does a star's temperature affect its absolute magnitude?
The absolute magnitude of a start will increase both:* If its surface temperature increases, and * If its diameter increases.
What factors affect the force between charges?
The force between charges is affected by the magnitude of the charges, the distance between the charges, and the medium in which the charges are located. The force increases with the magnitude of the charges and decreases with the distance between the charges. The medium can affect the force through its electric permittivity.
What three things effect magnitude?
The three things that affect magnitude are the distance between the observer and the event, the intensity of the event itself, and the type of measurement scale used to quantify the magnitude (e.g., Richter scale for earthquakes).
Does the distance from the sun affect the earth's temperature?
Because of the Earths atmosphere, the distance from the Sun, does not affect the temperature on the surface of the Earth. In the northern hemisphere, we are closer to the Sun in winter and the furthest away in summer.
Does the temperature of the golf ball affect the distance it travels?
yeah totally
What are two things that affect the magnitude of gravitational force?
The two things that affect the magnitude of gravitational force are the masses of the objects involved and the distance between them. The greater the masses of the objects, the stronger the gravitational force. Similarly, the closer the objects are, the stronger the gravitational force.
Does temperature affect gravity's force?
No, temperature does not affect the force of gravity. Gravity is a fundamental force of nature that is determined by the mass and distance between objects, not by temperature. Temperature may affect the properties of objects or materials, but it does not influence the strength of gravity.
How does temperature affect paint?
it affects it because the hotter the temperature is the aster paint will dry.
What are 2 factors that affect the strength of electric force?
Two factors that affect the strength of electric force are the distance between two charged objects (force decreases with distance) and the magnitude of the charges on the objects (force increases with charge size).
How does the distance of a planet from the sun affect the temperature?
the further away you are from the sun the colder the place is.
What affect the magnitude of force?
Gravitational Force = Gravitational Constant x mass of the first object x mass of the second object / distance squared. So what affects the magnitude is the masses of the objects and the distance between them. Gravitational Constant = 6.672 x 10^-11 N x m^2/kg^2 Both masses, and the distance between them.
