Who discovered the red shift in stars the same effect that causes sound waves to change pitch as an object moves towards or away from an observer?
Doppler.
Why the Doppler shift tells us only about the motion directly along the line of sight between a light source and an observer but not about motion across the celestial sphere?
A lateral (sideways) movement doesn't change the frequency, because in this case, the distance between the object and the observer isn't changing.
What is observer drift?
Observer drift is when two people who are observing something start agreeing with each other more and more often. For instance, if two teachers are rating final projects, and one of them rates more strictly than the other and they both know that, then the strict one might start thinking that he or she is too strict and the easy one might think he or she is not strict enough, and so they will change the way they rate things to be more similar. In teaching, sometimes this is a good thing, because you get more consistent grades, but in psychology, where a lot depends on the observer being unbiased, it is usually a bad thing because it tends to sway the results one way or another and corrupt the results of an experiment.
The mass of an object can be changed by?
The only practical way to change the mass of an object is to cut a piece of it off or glue another piece onto it. Also, it's been known for roughly 100 years that an object's mass appears to change when the object moves at high speed relative to the observer. This isn't really what you'd call a practical method. The speed required to make a noticeable change is hard to achieve, and it's kind of difficult to measure the mass of an object that whizzes by you at half the speed of light.
Go to another planet will your mass change?
Your mass will not change (unless you go on a diet). On different planets your weightwill change because you will be pulled down with a different force.
Does the frequency change if the observer moves?
actually the frequency donot change but apparent change in frequency is observed by the observer...........(may be this help u)
The appalanlachian mountains are almost 300 million years old. Which characteristic of these mountains would be different in the absence of erosion?
Shape. Erosion would change the shape of the tops of the mountains. It may also change in height a little, too.
For a stationary observer when the source of a sound is moving its?
When the source of a sound moves, the frequency noted by the observer will change. This is an example of Doppler's law. answer: its pitch appears to change.
When is a body said to be in motion in relation to an observer?
when position of the body with respect to an observer change with time then the body are said to be in motion.
What causes mountains to change?
A thing that can cause mountains to change is the temperature.
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.
What is a parallax error?
Parallax, more accurately motion parallax, is the change of angular position of two observations of a single object relative to each other as seen by an observer, caused by the motion of the observer. Simply put, it is the apparent shift of an object against a fixed background that is caused by a change in the observer's position.
When For a stationary observer when the source of a sound is moving it is?
C.pitch appears to change -apex
For a stationary observer when the source of a sound is moving its pitch appears to change?
true
When a stationary observer when the source of a sound is moving its pitch appears to change?
true
How does erosion change mountains over time?
it can change the mountains size and or shape. for example, erosion could change a mountain to a hill
Concealing the observer can be used to minimize the?
effect of change in the normal activity of that which is being observed.
