What else can I help you with?
When astronomers study distant galaxies they notice changes to the waves they observe describe the change to the waves they observe?
Because the universe as a whole is expanding, distant galaxies are moving away from us. As a result, electromagnetic waves emitted by those galaxies experience what is known as a red shift. Their wavelengths get longer.
How does the appearances of a constellation seem to change at night?
The biggest notable change is that they appear to move across the sky. This is of course due to Earth's rotation, and not the constellation moving. Standing looking at a constellation, you will not notice it move. You would need something to relate it to, like something on the horizon. If you look very carefully, you will see movement. Over the course of a night, it will appear to move in an arc shape, rising and then setting. If you regularly viewed a constellation across a few days or weeks, you would also notice that the time they rise is different and the time they are visible at a certain point in the sky is different. You will not notice any change in the stars in relation to each other within a constellation. Even during a lifetime, never mind one night, a particular constellation will look the same to you, as the changes would be so slight. If the moon is visible near a constellation, you would notice some movement over the course of a night in relation to stars in the constellation, and certainly over the course of a few nights. If there is a planet near them, you will notice some movement, but not near as much as the moon. The nearer planets, like Venus and Mars are more noticeable in their changes compared to other planets.
1 How would you describe the movement of the sun over 30 minutes?
You can describe the movement of the sun over 30 minutes as an arc. It continues to move in an arc motion, as it sets into the sky.
How do you notice a fake diamond?
Notice is a confusing word to use in this context -- perhaps you mean identify.A gemologist can help you determine whether your diamond is lab-created or a natural gem.
Who is the astronomer that notice a strange pattern in the orbit of Uranus?
Neptune
Who was the first explorer to notice different types of galaxies?
explorer? you probably mean astronomer.
How do you notice movement around?
by your ear
Do one direction notice their Arab fan?
yea after
When you moved the slides in different directions what changes in the images of the specimen under focus did you notice?
You should notice that the image in the microscope moves in the opposite direction to the movement of the slide. For example, if the specimen slide is moved top to bottom, the image seen moves from bottom to top. This can be very confusing.

How would you get One Direction to notice you?
Well....in Sweden they did notice some girls, who just happened to be flashing, but I'm sure you wouldn't want to do that Sometimes they might just notice you, of you don't even notice them...hmm
Expansion of pnr movement in sea shipment?
Public notice register
How do you get One Direction to notice you?
You can't. They won't notice you, they have trillions of other fans. Seriously you're not their only fan. Trust me i saw their fans.
What is constellation are all the stars in the constellation the same distance from us why do groups of stars continue to stay together?
"What is a constellation" - A visible group of stars, all in the same direction, that seem (to us) to form some picture."Are all the stars in the constellation the same distance" - No, they just happen to be in the same direction."Why do groups of stars continue to stay together" - They are extremely far away. They do move, but the distances are enormous, and it takes a while (say, a few thousands of years in the usual case) before we notice a movement."What is a constellation" - A visible group of stars, all in the same direction, that seem (to us) to form some picture."Are all the stars in the constellation the same distance" - No, they just happen to be in the same direction."Why do groups of stars continue to stay together" - They are extremely far away.

Why don't we notice the movement of sea-floor spreading?
Its too slow - about the same as your fingernails growing.
Why do you measure the gradient of a river in negative numbers?
Well, we could speculate. We do notice that from any point, the river always flows in the direction of the negative gradient ... that is, the direction of the greatest negative slope.
