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.
What else can I help you with?
An electric field gets stronger as you?
increase the charge or decrease the distance from the source of the field.
If two stars have the same absolute magnitude but one of the stars is farther from earth than the other one which star would appear brighter in the night sky?
If two stars have the same absolute magnitude, the one that is closer to Earth will appear brighter in the night sky. This is because brightness as perceived from Earth depends on both the intrinsic luminosity of the star (absolute magnitude) and its distance from us. The farther star, despite having the same intrinsic brightness, will have a dimmer apparent magnitude due to the greater distance light must travel to reach us.
Which changes would changes would correspond to a decrease in a star's absolute brightness?
A decrease in a star's absolute brightness could be caused by the star moving farther away from Earth, interstellar dust blocking some of its light, or a decrease in the star's temperature. All of these factors would result in less light reaching Earth, causing a decrease in the star's apparent brightness.
Even though this star has an absolute magnitude greater than that of sirius it looks dimmer from earth since its 100 times farther away?
The star's absolute magnitude is a measure of its intrinsic brightness. Sirius appears brighter from Earth than a star with a greater absolute magnitude because Sirius is closer to us, which affects its apparent brightness. The star with the greater absolute magnitude might be intrinsically brighter but is much farther away, leading to its fainter appearance from Earth.
What is higher for closer stars?
If they had the same intrinsic brightness, then yes. However stars vary enormously in their intrisic brightness, so Deneb is distant, but one of the brightest stars in the Northern sky, whereas proxima centuri is the closest star to us, but so dim that it cannot be seen without a mid-size telescope.
. A star that has the same apparent magnitude as Alpha Centauri could?
be larger than Alpha Centauri and farther away from Earth

increase the charge or decrease the distance from the source of the field.
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?

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.
How does distance from the epicenter affect the magnitude (height ) of the seismograph reading?
The seismograph reading tends to decrease in magnitude as the distance from the epicenter of an earthquake increases. This is because seismic waves lose intensity and amplitude as they travel through the Earth's crust, resulting in a weaker signal being recorded at farther distances from the epicenter.
What happens when you decrease or increase the wave period?
When you decrease the wave period, the waves will be closer together and have a higher frequency. This can create choppier and rougher conditions on the water. When you increase the wave period, the waves will be farther apart and have a lower frequency, resulting in smoother sailing conditions with longer intervals between waves.
As you get farther away from the center of the earth your weight will increase or decrease?
As you move away from the center of the Earth, your weight will decrease. This is because weight is the force of gravity acting on an object, and gravity weakens with increasing distance from the center of the Earth.
