Question

L=36000 км c=3*10^8 м/с t-?

Answer 1

L = 36 000 km=36 000 000 m
3*10^8=300000000 м/с
сл-но t=L÷c=0.12 cek

Answer 2

It seems that you have given the value for the circumference of a circle L, and the speed of light c. To find the time taken for light to travel around this circle, we can use the formula:

t = L / c

Substituting the given values, we get:

t = 36000 km / (3 x 10^8 m/s)

We need to convert km to meters to ensure that our units are consistent:

1 km = 1000 m

t = (36000 x 1000 m) / (3 x 10^8 m/s)

Simplifying the expression:

t = 120 s

Therefore, the time taken for light to travel around a circle with circumference of 36000 km is 120 seconds or 2 minutes.
