ALWAYS use significant figure rules. Remember that these rules apply to all numbers that are measurements.
Light travels approximately 982,080,000 ft/s, and one year has approximately 32,000,000 seconds. A light year is the distance light travels in one year.

Calculate the distance of one light year in feet.

Respuesta :

The answer is 3.142656E16.

Answer:

The distance of one light year is [tex]3.142\times 10^{16} feet[/tex].

Explanation:

Let the distance light travels in one year be D

Speed of the light = S = 982,080,000 feet/second

Time taken by the light = T =  1 year = 32,000,000 seconds

Speed of moving body is calculated by the dividing distance from the time taken by the body to cover the same distance.

[tex]Speed=\frac{Distance}{time}[/tex]

[tex]S=\frac{D}{T}[/tex]

[tex]D=S\times T=982,080,000 feet/second\times 32,000,000 seconds[/tex] [tex]D=3.142\times 10^{16} feet[/tex]

The distance of one light year is [tex]3.142\times 10^{16} feet[/tex].
