Question

How far does a beam of light travel through space in one 365-day year? (c = 3.0 × 10^8 m/s)

Answer 1

Distance
`=9.46* 10^(15)m`

Step-by-step explanation:

We have given total time 1 year = 365 days

We know that 1 day =24 hour

So 365 days =365×24 =8760 hour

In 1 hour 3600 sec

So 8760 hour = 8760×3600
`=3.1536* 10^7 sec`

Speed of light
`c=3* 10^8m/sec`

We know that distance = speed ×time
`=3.1536* 10^7* 3* 10^8=9.46* 10^(15)m`
