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.

The distance of one light year is .

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.

The distance of one light year is .

if the thermos has a vacuum innner, then heat through conv currents and conduction are reduced = vacuum flask

explanation:

as the height from which the ruler was dropped increased, the speed of the ruler at ryan's hand increased.
