The distance from the earth to the sun is 1.496 x 1011 meters. the speed of light is 3 x 108 meters per second. show that correct to 3 significant figures, light will take 0.139 hours to travel from the sun to the earth

The time taken by light to travel from the sun to the earth is 0.139 hours and this can be determined by using the formula of speed.

Given :

The following steps can be used in order to show that light will take 0.139 hours to travel from the sun to the earth:

Step 1 - Remember in 1 hour there are 3600 seconds.

Step 2 - So, the speed of light in m/hour is:

m/hour

Step 3 - So, the time taken by light to travel from the sun to the earth is:

Step 4 - Simplify the above expression.

t = 0.139 hours

speed of light = 3 x 10^8 meters / second There are 3,600 seconnds per hour so,

speed of light = 3 x 10^8 meters / second * 3,600 = 1.08 x 10^12 meters / hour

1.496 x 10^11 meters ÷ 1.08 x 10^12 meters/hour = .1385 hours which rounds to

.139 hours  

Step-by-step explanation:

1. is 4 and 2. is 3

step-by-step explanation:

so if you look at the first one you see that 1 is to 4 and 2 is to 8 and so on, so you can see for every 1 there is a times 4 so if it were 3 then it would be 3*4 and it is 12

for number 2 it is 3 because 1 is to 3 and 2 is to 6 so for every 1 there is 3 so if it were 3 then there would be 3*3 = 9

4th option is correct xy=-10

if this was to u plzz mark me the brainliest
