Acceleration is a change in speed or direction of motion. You
haven't said anything about changes of speed or direction.

What unit of measurement is used for the radius?
Any measure of length, such as meters, centimeters, or light-years.
What units is the radius of a circle measured in?
Any unit of length: millimeter, meter, kilometer, light-year, etc.
Why might using speed of light to determine the length of the meter be more reliable than using a measured distance around earth?
The speed of light in vacuum is a universal constant. The distance around the earth depends on the line of measurement. Because of its rotation, the earth is not a perfect sphere: its equatorial radius is 0.3% greater than its polar radius. Consequently the measurement is affected by the exact line along which the radius is measured. Furthermore, there are two kinds of variations in the equatorial radius. One is a long-term variation caused by the distribution of mass on the surface: possibly the ocean mass. There is also the short term variation caused by the gravitational pull of the moon.
What is the schwarzschild radius of earth?
The schwarzschild radius of the Earth is about 8.7 x 10 to the negative 3m. The schwarzschild radius is the radis of a sphere that is around a non-rotating blackhole. You find the Rs, or radis, by multiplying the gravitational constant(G), the mass(M), and two. You divide this by the speed of light(c) squared.
How does the moon affects life on earth?
Tides, length of the day, variable light at night (for hunting).
Would you feel heavy or light on Uranus?
You would feel heavier. The acceleration due to gravity on Uranus is 10.72, while the acceleration due to gravity of Earth is 9.8 m/s2 (or 9.81, it depends on who you ask.).
What is the radius of Andromeda?
It is approximately 75,000 light years in radius
How do you calculate the average radius of earth's orbit lif it takes 500seconds for light to reach earth from the sun?
Speed of light = 186,282 miles per second.500 seconds at this speed = (500 x 186,282) = 93,141,000 miles
Light from a star travels from earth in a straight line at a constant speed of 300000 kilometers per second What is the acceleration of the light?
The speed of light is a constant, so the acceleration is zero. However, light IS affected by gravity, and gravity causes an acceleration. How does this balance? The light moves at the same speed - the speed of light, abbreviated "c" - but loses or gains energy as the light moves toward or away from the gravity source. In gaining energy (without speeding up!) the frequency of the light is increased and the wavelength of the light (or any electromagnetic energy) is decreased, In losing energy, the wavelength is increased and the wavelength decreased. This could be a trick question, of course. Light from a star wouldn't be travelling from earth, unless we are talking about reflected light, which would not be particularly intense, but it is not out of the question.
How do you Calculate the distance from Earth to sun?
By unit of length and distance and conversion ,we can say that the distance from Earth to sun is calculated with the help of light years.
Formula for the radius of the curvature of the concave lens?
radius of curvature is double of focal length. therefore, the formula is: 1/f = (n-1)[ 1/R1 - 1/R2 + (n-1)d/nR1R2] here f= focal length n=refractive index R1=radius of curvature of first surface R2=radius of curvature of 2nd surface d=thickness of the lens using this, if you know rest all except one, then you can calculate that.
What is the distance from Regulus to Earth in miles?
Regulus is 77.5 light-years away from our solar system. (The diameter of Earth's orbital radius is 16 light-MINUTES, so our orbit around the Sun doesn't make any significant difference.)
