No shift under those conditions.

How do you know when the earth is moving?
well night and day , wind direction , sun location and star location
Which direction does the earth move eastwards or westwards?
The earth moves from west to east; it moves eastward. This is why we observe the sun rising in the east. We are moving toward it. From the north, we would see this as a counter-clockwise rotation of the earth on its axis.
What might geologist expect to see after a earth-quake?
They expect to see earth's crust change.
Is earth's crust stationary or moving?
Moving
Why Tropical revolution storm recurve?
Tropical Cyclone usually moves Westwards, but as they turn with Earth rotation they experiences Precession and this results in Tropical Cyclones to move in Pole Direction ( Nothwards). As Earth rotates from West to East, Tropical Cyclones also experiences acceleration in East direction. Thus Tropical Cyclone (moving towards Pole) re curves to East direction.
What type of shift in the spectrum would you expect from a star that was moving in the same direction as earth at the same speed of earth?
You would expect no shift in its spectrum. Any shift one way or the other is the result ofmotion either toward or away from Earth. Motion parallel to ours or across our line of sighthas no effect on the observed spectrum of the object.
If a galaxy is moving towards the earth what direction does its spectrum move?
It will be blue shifted
What is the spectrum of an object that shows blueshift?
The object moving directly towards earth
What direction does the earth spinrotate?
You're moving east - that's the definition (in fact) of "east". [And at dawn (when standing) your head is pointed in the direction that the earth is moving around the sun.]
What happen to the spectrum of a star moving toward the earth away from the earth?
If a star is moving towards Earth. The light is seen as 'blue shifted'. As we look at our sun, on the colour spectrum, black lines appear. When looking at distant stars, we can tell if they are moving away from us (Red shift) or getting closer to us (Blue shift). This is because the black lines shift to the red or blue end of the spectrum depending on which direction the star is travelling.
Does the velocity of a star toward or away from earth determine measuring the shift of its spectral lines?
Yes. If the star is moving away from the Earth, its spectral lines will shift towards the red end of the spectrum. If it is moving towards the Earth, its spectral lines will shift towards the violet end of the spectrum. This is due to Doppler effect.
Which direction from earth is mercury?
It really doesn't have deffonent direction because they are always moving. But it is NEVER sount because Mercury is in front of earth on the solar system.
In which direction are nearby all galaxies moving relative to earth?
Nearly all galaxies are moving away from our galaxie and planet.
In which direction are nearly all galaxies moving relative to earth?
they are moving in all directions away, toward, sideways relative to EarthNearly all galaxies are moving away from the Earth. This is because the universe is expanding.
What direction does the earth go around his axis?
The Earth turns anticlockwise (counterclockwise in USA), moving from the West towards the East.
How do you use spectral lines to determine if a galaxy is moving towards earth or away from earth?
The spectral lines move towards one direction, or towards the other direction, depending on the relative speed.
What would be evidence of a galaxy moving towards earth?
A blueshift in the galaxy's spectrum - that is, the frequency of the light, as observed by us, is greater than when it was emitted.
