Question

what is a light year ? the distance between the earth and sun is 150 multiply 10 raise to power 6 kilometre Express this distance in light year​

Answer 1

Answer:

The distance between the Earth and the Sun is d=1.58\times 10^{-5}\ light\ yeard=1.58×10

−5

light year .

Explanation:

It is given that, the distance between the Earth and the Sun is,

d=150\times 10^6\ kmd=150×10

6

km

Since,

1 km = 1000 m

d=150\times 10^9\ md=150×10

9

m

We need to convert the distance in light year. We know that,

1\ light\ year=9.461\times10^{15}\ m1 light year=9.461×10

15

m

So,

1\ m=1.057\times 10^{-16}\ ly1 m=1.057×10

−16

ly

150\times 10^9\ m=1.057\times 10^{-16}\times 150\times 10^9150×10

9

m=1.057×10

−16

×150×10

9

d=1.58\times 10^{-5}\ light\ yeard=1.58×10

−5

light year

So, the distance between the Earth and the Sun is d=1.58\times 10^{-5}\ light\ yeard=1.58×10

−5

light year . Hence, this is the required solution.
