Would the apparent magnitude of the sun increase or decrease if it were farther away from Earth?

The numeric value of the apparent magnitude would increase, since bright objects have lower magnitude values than dim objects.
To give some actual numbers as an example: the Sun has an apparent magnitude of about -27. It is much, much brighter than the moon, which at its brightest has an apparent magnitude of -13 or so.

Keeping the location of the effort constant Will the effort increase if the load is moved farther away from the fulcrum?
The magnitude of the effort is controlled by you, not by the distance of the load from the fulcrum. Moving the load farther away from the fulcrum has no effect on the effort. But if you want to leave the effort where it is and still lift the load with the lever, then you're going to have to increase the effort.
Will the age of the ice increase or decrease the farther down towards the ice core?
The age of the ice increases as you go further down towards the ice core. The deeper you go, the older the ice.
Why can two stars can have the same apparent magnitude and different total magnitudes?
Two different stars with different luminosity may appear to have the same brightness to an observer because the brighter may be more distant. This illustrates the need in astronomy to help range distant stars; since apparent magnitude alone will not yield enough information to gauge distance. The establishment of a "standard candle" or object of known brightness can be used for comparison; these can be established through various means including statistical models, observation of variable stars, behavior of nearby supernovae, etc. Once the distance of a star is known, the absolute magnitude can be derived from the apparent magnitude using the inverse-square law.
How bright is a star which is actually at a distance of 32.6 light years away from earth called?

Why does a planet's distance from the sun affect the solar radiation a planet receives?
The further one is from the sun the less radiation is received, according to an inverse square root law. This means that if you increase your distance by 2 the solar radiation will decrease by 2. if you increase your distance by 3 the solar radiation will decrease by 9 and so forth.
. A star that has the same apparent magnitude as Alpha Centauri could?
be larger than Alpha Centauri and farther away from Earth
As you get farther away from the center of the earth your weight will increase or decrease?
It will decrease not by much though it is not noticeable compared to the earths radius
Does gravity increase or decrease when the distance increases between two objects?
Gravity decrease as you get farther, and every mass has gravitational pull.
Why does Arcturus star have greater absolute magnitude than the sun buy a much lower apparent magnitude?
The apparent magnitude is how bright the star appears to us, but stars are all at different distances so that a star that is really bright might look dim because it is very far away. So the absolute magnitude measures how bright the star would look if it was placed at a standard distance of 10 parsecs. When the absolute magnitude is greater than the apparent magnitude, it just means that it is closer than 10 pc. The brightest stars have absolute magnitudes around -7.
Why doesn't apparent magnitude actually measure the brightness of the star?
The apparent magnitude of the Sun is listed as -26.74. I want to know what is the formula used to compute this? How is this figure of -26.74 arrived at? Can this formula be employed for calculating the apparent magnitudes of stars of different spectral types too?

What happens to the brightness of the star as you observe it from farther away?
The brightness of star will decrease as you observe it from farther away.
What happen to the brightness of a star as you observe it from farther away?
The brightness of star will decrease as you observe it from farther away.
Why positive feedback unstable?
A: To feedback more of the same signal from the output to increase the input to farther increase the output and farther increase the input will ultimately saturate the system
The brightness of a star as seen from earth?
Absolute magnitude. Two stars of the same absolute magnitude usually do not have the same apparent magnitude because one may be much farther from us than the other. The other that is farther away will appear dimmer. To compare absolute brightness, astronomers determine what magnitude the stars would have if they were at a standard distance of about 32.6 light years. The sun has an apparent magnitude of -26.7, if located at a distance of 32.6 light years, have an absolute magnitude of 5. Stars with absolute magnitude values lower than 5 are brighter than the sun. Because of their distance, however, they appear much dimmer.A lot brighter than you think actually.
Will the age of the ice increase or decrease the farther down towards the ice core?
The age of the ice increases as you go further down towards the ice core. The deeper you go, the older the ice.
Do the speed of the planets decrease when they are far from the sun?
They are going faster so they are farther from the sun.
