What is the difference between apparent magnitude and surface magnitude?

The two types are apparent magnitude, the magnitude of a star as it appears to us, and absolute magnitude, which is what a star's apparent magnitude would be at a standard distance of ten parsecs.

How does the sun compare to other stars in terms of surface temperature apparent magnitude absolute magnitude and size?
Our Sun is pretty much average. It's larger than about 60 to 70 % of the other stars in the Milky Way; the estimate increases as we keep discovering more and more very small and very dim brown dwarf "stars" (that are right on the boundary between "star" and "not star").
What is the relationship between the surface area of the skin amount and heat lost through the skin?
the difference between this is that surface area
What is the cost of a synthetic surface track?
This will often depend on how much of the material that you get. There is also a difference between the type of material you choose.
What is the radius of Barnard's Star?
Barnards star is a highly variable star and can have different brightnesses.Apparent magnitude - 9.54Absolute magnitude - 13.22See related question about the difference between absolute and apparent magnitude
What is the name of the plane in the sea at which salinity changes?
You might mean a halocline - that's when there's a great enough difference in salinity that the water separates into two phases, with a surface between them.
What is the difference between apparent surface area and accepted surface area?

What are the relationships between apparent magnitude and absolute magnitude?
Apparent magnitude is the brightness of an object as seen from Earth without any atmosphere.Absolute magnitude is the brightness of an object as seen from a predetermined distance, depending on the object.For planets, the distance used is 1 AU (Astronomical Units). Stars and galaxies use 10 parsecs which is about 32.616 light years.The dimmer an object is the higher the positive value. The brighter an object is the higher the negative value.Examples:The Sun has an apparent magnitude of -26.74 but an absolute magnitude of 4.83Sirius has an apparent magnitude of -1.46 but an absolute magnitude of -1.42This means that from Earth, the Sun is a lot brighter, but if the Sun was replaced by Sirius, Sirius would be 25 times more luminous.See related links for more information
What is difference between emitted radiation heat and reflected radiation heat?
The magnitude of the incident angle with the normal of the reflection surface and reflection angle with the normal of the surface are the same. The direction of the reflection is away form the surface and the incident is toward the surface.
How does the sun compare to other stars in terms of surface temperature apparent absolute magnatuide and size?
Temperatures in the sun's middle atmosphere, the Chromosphere are 4,225°C to 6,000°C. In the sun's outer atmosphere, or Corona, temperatures may reach 2,000,000°C, while stars are related to colour: Stars that have the lowest surface temperatures (below 3,500 °C)are red. Stars that have the highest surface temperatures (above 25,000 °C) are blue. The Apparent Magnitude of the sun is less than the other stars. Some stars are actually more luminous, or brighter than the sun is. If these stars are located far from Earth, they may not appear bright to us. Using only their eyes, ancient astronomers described star brightness by magnitude. They called the brightest stars they could see 'first magnitude' and the faintest stars they could see 'sixth magnitude'. Astronomers using telescopes see many stars that are too dim to see through the naked eye. Rather than replacing the magnitude system, astronomers added to it. Today, the brightest stars have a magnitude of about -2. The faintest stars that we can see through a telescope have a magnitude of +30. Sirius the brightest star in the night sky has an apparent magnitude of -1.46. To the naked eye, the sun has apparent magnitude of -26.8, even though it is not as luminous a star as Sirius is. The sun is simply located closer to Earth. The apparent magnitude of the sun is -26.8. However the absolute magnitude of the sun is +4.8 which is typical of many stars. Now compare the sun, which is located 8.3 light minutes from Earth, to Sirius, which is located 8.6 light years from Earth. Sirius has an apparent magnitude of -1.46 and an absolute magnitude of +1.4. Therefore, Sirius is much more luminous than the sun is.
The difference between computer and surface computer?
the computer is the device. the computer surface is the surface it sits on

Which stars always have large positive absolute magnitude?
Does it mean that the star is a main sequesnce star? ( . Y . ) The above isn't true. A star can be a blue supergiant and be on the main sequence but still not be even visible to us, therefore the apparent and absolute magnitude wouldn't be the same. But to answer your question, I don't think it has a name, it just means that you are seeing the star's absolute and apparent magnitude at the same time, so if you placed the star at 32.6 light years away(the absolute magnitude scale)then the star would not appear to change in brightness
Is it true that weight affects the amount of friction between the object and a surface?
Yes. Weight, being a force perpendicular to the surface, affects the magnitude of the friction, but not the friction coefficient.
What is the relationship between the surface area of the skin amount and heat lost through the skin?
the difference between this is that surface area
What is the difference between a surface current and a deep current?
A surface current is on the surface and a deep water current is deep beneath the surface.
