The speed of light is a constant for the material through which is moves. Because of this, a moving source of light emits light at the speed of light regardless of its own velocity.Answer and Explanation: Become
Hubble took many photos through the observatory's telescope, and it allowed him to calculate the distance of other galaxies by comparing the varying degrees of luminosity in the stars themselves. Although there was no evidence suggesting the size of the other galaxies that Hubble discovered, he ...
How does the resolving power of a 9 m telescope compare with that of a Hubble space telescope? Define solar constant. What is solar constant value? Fill in the blank. According to Hubble's law, the greater a galaxy's redshift, the ___. What are...
Observations are the key to understanding. We assume that redshift is a measure of velocity? We asssum that the King wears invisible robes. The bottom line is: How can space expand? It cannot be answered by science, but for by ad hoc ideas. This is quite interesting. The dark ...
In our expanding universe, everything moves away from everything else More distant objects recede more rapidly This is universal: every distant object is receding from us Redshift measures expansion rather than velocity Is this velocity? No it’s really expansion! Light leaves a galaxy, taking ti...
Now, to calculate the gravitational force between the Earth and the Sun at the Earth's average orbital radius from the Sun, here is the basic data: Sun: mass 1.989 X 1032 gr Earth: mass 5.976 X 1027 gr; average orbital radius from Sun 1.49596 X 1013 cm So that… F = 1.989 X 1032...
Relativistic mass m is the mass of a body that changes with the speed of the body as this speed approaches close to the speed of light. The relation between relativistic mass and rest mass is m=m01−v2c2, where v is the magnitude of the velocity and c is the speed ...
