What else can I help you with?
Does velocity have to be represented by north east etc?
If you call it "velocity" then you have to tell what direction it points.If you only tell how fast it is but you don't tell the direction, then it's "speed", not velocity.
Is enormous an adjective that describes a sandwich?
If it is a really big sandwich you could probably say it is enormous. That wouldn't tell you how it tastes or what is in it but it would tell you it is very large.
How can you tell an object has moved?
Because of its velocity (velocity is the rate of change of position), an object will move. An object is stationary if it has no velocity because it will not be able to move without velocity. Therefore, you can tell that an object has moved because of velocity.
How can you figure out velocity?
You check out the speed and direction, and times them together, and it will tell you the velocity of the object.
What does the red shift tell scientists?
The redshift tells scientists how fast a star or galaxy is moving away from us.
What does the redshift tell us about the universe?
Redshift is a phenomenon where light from distant galaxies appears redder than expected due to the expansion of the universe. It tells us that the universe is expanding and provides evidence for the Big Bang theory. By studying the redshift of galaxies, scientists can understand the rate of expansion and the age of the universe.
What is red-shift and what does the size of the redshift tell us about the distant galaxies?
Red shift is the apparent elongation of the wavelength of light reaching us from distant sources of light due to the expansion of space in between. The amount of red shift can be used to work out the recessional velocity of a galaxy and it's distance from us.
How did Hubble tell the universe was expandining?
By the redshift of the galaxies. In general, the farther away a galaxy is from us, the faster it moves away from us.
How can astronomers tell what a distant object's velocity?
By using the habo space telescle to detect the object's velocity
When an arrow is used to show velocity what does the arrow tell you?
The arrow's direction indicates the velocity's direction, while the arrow's length represents the velocity's magnitude.
Are speed and velocity caluclated the same way?
Their 'sizes' are. But if you want it to be a velocity, thenyou also have to tell the direction of the speed.
What does the slope of the line on a distance-time graph tell you?
velocity
