Does angular speed depend on distance?
when something moves with constant angular speed (w), as in a rotating disk, the speed (v) as you move away from the center depends on distance (r), but the angular speed does not. Mathematically, v = wr.
In 1.8 s a smart and swift dachshund caught his prey that was 8.5 m away. What is the dog's speed?
You simply need to divide the distance by the speed. This will give you the AVERAGE speed during the 1.8 seconds in this case.
A sonar station picks up a return signal after 3seconds How far away is object?
In order to calculate a distance, we must use the equation Speed=Distance/Time and rearrange it by multiplying both sides by time to get Distance=Speed*Time. If the station is measuring time for a return signal, the signal only spent half its total time traveling to the object, or in this case, 1.5 seconds. Sonar stations receive signals sent via sound-waves, but since the speed of sound varies in different mediums, the speed, and thus the distance, depends on where the sonar station is. If the station is above ground, the speed of sound is approximately 343 meters/second, so the object would have to be 514.5 meters away. If however the station and object were underwater, the speed of sound is about 1497 meters/second (varying depending on water temperature and composition) meaning the object would be 2245.5 meters away.
How does the distance from a page to a light bulb affect the amount of light that illuminates the paper's surface?
The intensity of light or other linear waves radiating from a source is inversely proportional to the square of the distance from the source; so an object (of the same size) twice as far away, receives only one-quarter the energy.
What is the relationship between the force of gravity and distance?
The forces of gravity between you and another mass are stronger when you're closer to the other mass, and weaker when you're farther away from it. Added: Explained by this equation. F = G(m1m2)/r2 The force of gravity is inversely proportional to the distance between the two bodies.
how distance to a galaxy and speed are related?
Relationship between distance of galaxy and its speed is that galaxies are moving away from the Earth at velocities proportional to their distance. In other words, the further they are the faster they are moving away from us.
He originally suggested that galaxies are moving farther away He also suggested that the distance of a galaxy is proportional to its recessional speed who is He?
Edwin Hubble.
Is a farther away galaxy from us moving away faster?
Yes, furthest the galaxy more it's speed of moving away from each other also universe is expanding continuously therefore space between galaxies is also expanding . Redshift is directly proportional to the distance b/w the galaxies therefore distant galaxies red-shifted at faster rate
What does the red shift measure?
Redshift measure the recession speed of stars and galaxies. These speeds are proportional to distance--the farther a star or galaxy is from a given location in space, the faster that entity is moving away from that location. This proportionality is given as Hubble's Law. In general, everything is moving away from everything else, and the furthe away, the faster the acceleration (local movements not included). Dick
According to Hubbles law galaxies are retreating at a speed that is proportional to their?
I'm not convinced that your proposition is correct. I realize that cosmologists use a lot of simplification in their descriptions, for friendly reasons, but I always prefer to keep things fairly straight. It is my reading of Hubble that he postulated that remote galaxies were receding -- at the time they emitted the light which we are now receiving -- from us at a speed which was proportional to the distance from where they were then to where we are now. How one interprets the concept of distance, in view of the separately postulated "expansion of space" and time-dependence of the "scaling factor" is obviously now a compounding, related issue, which lay outside Hubble's purview. Hubble's law does not specify, based upon the observed redshift (whether non-Doppler or not) what is (i.e. is now) the distance between us and the galaxy. It is considered simplest to assume that the velocity of separation is and continues radially uniform, and therefore has increased during the time it took the light to reach us. If you need to know the current (our observing time) location of the remote galaxy and the velocity of its separation from us now, you will need to apply further calculations to the Hubble data.
Light year distance to the stars?
The closest star is the Sun - about 8 light-minutes away. The closest star after that is at a distance of 4.3 light-years; the farthest observable galaxies (galaxies are made up of stars) are at a distance of over 40 billion light-years.The closest star is the Sun - about 8 light-minutes away.

Who classified the galaxies according to shape and distance and concluded that galaxies move away from each other at a rate dependent to the distance between them?
Edwin Hubble, in the 1920s. Later they named a telescope after him.
Are any Galaxies moving away at half the speed of light or faster?
Yes. The farthest known galaxies move away from us faster than the speed of light. While this is not possible for nearby objects, in this case space itself is expanding.
Will you move into another galaxy?
Not in the near future. Other galaxies are hundreds of thousands, or millions, of light-years away; travelling at the speed of light, it would thus take millions of years to travel to most galaxies; travelling at a lower speed would, of course, take longer.Not in the near future.

How and did they figure out about the big bang?
One important clue is the Doppler effect - the redshift of distant galaxies. It turns out that the greater the distance to a galaxy, the faster it moves away from us.One important clue is the Doppler effect - the redshift of distant galaxies.

Do Galaxies Move away from the area of the big bang through time and the speed they're travelling?
Galaxies Move away from the area of the big bang with time at speeds higher than that of light.
Do galaxies moves away from the sun by red shift?
Galaxies that are moving away from the sun are red shifted, that is the light from them looks more red to us that it is when it is emitted. This is due to the speed of the galaxy moving away from which in effect stretches out the wavelengths of the light. Red shift is not the method by which galaxies move away from the sun, rather, it is a consequence of it.
