One dimmer star can be closer than a brighter star that is far away. Light flux decreases as the square of the distance. A star that is three times as far away will have to shine nine times brighter than the closer star (absolute magnitude) to appear to have the same magnitude (apparent magnitude).
Because apparent magnitude is the brightness of a star, as seen from Earth, whereas absolute magnitude is the brightness of a star as seen from the same distance - about 32.6 light years away.

Frequency: Frequency is also equal to the wavelength divided by the velocity and is designated as the number of cycles (or peaks) per second. Amplitude: Amplitude is the absolute value of the magnitude of the displacement of a wave from a mean value and is designated as mV
Of course not.
Yes, it is possible to recycle glossy cardboard. Glossy cardboard can be recycled just like regular cardboard, but it may need to be sorted separately in some recycling programs.
Yes, anti-atoms are possible and have been produced in laboratories. Anti-atoms consist of anti-protons and positrons (the antimatter counterpart of electrons) bound together in the same way that regular atoms are. When an anti-atom comes into contact with a regular atom, they annihilate each other, releasing a large amount of energy.
Yes, if the matter surrounding one star is more dense than that surrounding the other it would appear to be less bright.
It is a very normal type of star with a G2 spectrum and absolute magnitude of 4.5.
Because of different luminosities and distances from Earth, Stars have brightness defined as either:A) Apparent Magnitude - [See Link]. As seen from EarthThe SunRed GiantWhite DwarfNova (Depending on location)B) Absolute Magnitude - [See Link].

Henrietta Leavitt studied Cepheid variables, a certain type of variable star with brightness that varies in a very regular cycle. By studying Cepheid variables in the Magellanic clouds, she discovered a simple relationship between the brightness of a Cepheid variable star and the length of time the cycle takes to repeat itself. To do this she used the fact that all such variables in the clouds are at the same distance from us, approximately. This allowed her to calculate the absolute magnitude of the star just by measuring the time period of the variation in brightness. The importance of this technique is that Cepheid variables can be found in more distant galaxies, and this provides a yardstick for finding out how far away they are. All you have to do is find a Cepheid variable in a galaxy and measure its variation period, then you know its absolute magnitude. You already know its apparent magnitude so it becomes possible to calculate how far away it is. This is one of the methods that astronomers used in the early 20th century to reveal the unexpectedly huge distances of other galaxies in the universe. Let's hear it for Miss Henrietta Leavitt!

No it is not.

Not possible, by definition. Regular implies equilateral.
An absolute scale is a system of measurement that begins at zero and only goes one way. So since on a regular Fahrenheit scale where absolute zero is −459.67, you would say absolute zero is zero and freezing point becomes 491.67.
yes
