Alpha century is 4 light years from earth how long would it take for light form alpha centauri to reach earth

Given:

Distance of alpha century = 4 light year

Speed of light = 3 × m

To find:

Time taken by light to reach earth = ?

Formula used:

Distance = speed × time

Solution:

Distance = 4 light year

Converting distance from light year into meter

1 light year = 365 × 24 × 60 × 60

4 light year = 4 × 365 × 24 × 60 × 60× 3 ×

As we know,

Distance = speed × time

s = v × t

Where s = distance

v = velocity

t = time

So,t =

t = }{3 ×

t = 4 × 365 × 24 × 60 × 60 second

t = 4 year

Thus, Time taken by light to reach earth from alpha century is 4 earth year.

higher potential

explanation:

because it is in a high speed so it must move into a of high potential
