Why is The moon surface visible to an observer on earth?
Its surface is visible because of how AU's (Astronomical Units) it is away from the Earth.
Is it true or false the second postulate of special relativity says that the speed of light in empty space depends on the motion of the source or of the observer?
False. The speed of light in empty space is a constant, independent of the motion of the source/observer. An observer travelling towards or away from a light source at 99% the speed of light would measure light going the same speed as an observer stationary relative to the light source.
What indicate redshifting to astronomers?
The object is moving away from the observer.
Why do you experience different seasons as the earth orbits the sun?
Because Earth's orbit is elliptical, not circular. So, when Earth is farthest away from the sun, it is winter, and when its closest to the sun, it is summer.
How far away will the James Webb telescope be from Earth?
Webb is going to the second Lagrange (L2) point, which is 1 million miles (1.5 million km) away from Earth.
Why does the Moon's surface is visible to an observer on earth?
Its surface is visible because of how AU's (Astronomical Units) it is away from the Earth.

Where do meteors happen the most?
Meteors can be seen from anywhere where it's dark. That means the observer has to be on the half of Earth that is turned away from the Sun. More meteors are usually seen after midnight because then the observer is on the 'front' part of the Earth as it travels through space.
What are the four types in Doppler effect?
Frequency change when 1)Source moves toward the observer 2)Source moves away from the observer 3)Observer moves toward sourse 4)Observer move away from the sourse, otherthan these observer and sourse moving away or towards each other.
When a hemisphere of the Earth is titled away form the sun what does it experience?
Night.
Why does the number of circumpolar constellations depend on the latitude of the observer?
As an observer moves away from the equator, towards the north or south pole, there are more constellations that the rotation of the earth does not ever block from his or her view throughout one full rotation.
What are the kinds of curve mirror?
They are: concave (curved away from the observer) convex (curved toward the observer)
Does a red shift indicates that objects are moving toward earth?
Red shift occurs when an object moves away from the observer. So as you are on Earth, it is when objects move away from Earth. (Blue shift as it moves closer.) A star's red shift could be due to losing energy to gravity.
When a sound source is moving away from an observer the observer will hear a lower pitch. This is due to?
This is due to the Doppler effect.
Over several years the apparent size of the sun as viewed by an observer on Earth will?
i believe the answer is it will vary in a cyclic manner because the earth moves farther away from the sun in summer in the northern hemisphere and then closer in the winter
What way does a star a appear in night sky?
A star can only appear to an observer on the dark side of the Earth, facing away from the Sun, so that the star's light can be seen.
Is it true or false the second postulate of special relativity says that the speed of light in empty space depends on the motion of the source or of the observer?
False. The speed of light in empty space is a constant, independent of the motion of the source/observer. An observer travelling towards or away from a light source at 99% the speed of light would measure light going the same speed as an observer stationary relative to the light source.
