Question

If the velocity of the light is 3.0 x 10 raise to 8 metre per second calculate the distance travelled by the light in a light year Express it in the standard form

Answer 1

Answer:

sorry I'm not understanding this question please follow me dear

Answer 2

ANSWER!:

According to the question:

Time taken to cover the distance = 2.00 ns

= 2.00 × 10–9 s

Speed of light = 3.0 × 108 ms–1

We know speed = distance/time

Or distance = speed x time

Therefore Distance travelled by light in 2.00 ns

= Speed of light × Time taken

= (3.0 × 108 ms –1) (2.00 × 10–9 s)

= 6.00 × 10–1 m

= 0.600 m
