Question

how long does it take light travelling at3*10^8 m/s to across a room 6 m long?

Answer 1

distance = speed * time

so plug in your numbers

Answer 2

Time=distance/speed

=6/3×10^8
=2×10^-9seconds

Answer 3

looks more like 2*10^-8 to me.

Answer 4

To find out how long it takes for light to travel across a room, you need to use the formula:

Time = Distance / Speed

In this case, the speed of light is given as 3 * 10^8 m/s, and the distance is the length of the room, which is 6 meters. Plugging these values into the formula, we get:

Time = 6 meters / (3 * 10^8 m/s)

To simplify the calculation, we can express the speed of light in scientific notation as 3 * 10^8 m/s:

Time = 6 meters / 3 * 10^8 m/s

Now, divide the distance by the speed of light:

Time = 6 / 3 * 10^8

Now, divide 6 by 3:

Time = 2 * 10^-8 seconds

Hence, it takes approximately 2 * 10^-8 seconds (or 0.00000002 seconds) for light to travel across a room that is 6 meters long.
