You did not record another distances.
The standard well-known, simply remembered approximation for the worth of the Velocity of Gentle in vacuum in Imperial items is 186,000 miles per second.
[More accurately it is 186,282.397 miles per second.]
The gap is given in items of ft, and the reply is requested to be in nano-seconds.
So, to check meaningfully, you should get the pace expressed in items of ft per nano-second.
Recall 1 mile = 1,760 yards; 1 yard = 3 ft.
So there are 5,280 ft in a single mile.
Therefore mild will journey 186,000 x 5,280 = 982,080,000 ft in a single second.
[By using the more accurate figure for c you would get 6.608572 nano-seconds.]
So, to precise this pace when it comes to ft per nano-second, merely divide by 1,000,000,000.
Begin by writing the worth as 982,080,000. (i.e. with the express decimal level on the finish.)
Then transfer the decimal level left 9 occasions, yielding 0.98208.
To acquire your goal period, divide the gap in ft by the pace in ft per nano-second.
Viz. 6.5 / 0.98208 = 6.62 nano-seconds.
[By using the more accurate figure for c you would get 6.608572 nano-seconds.]
This may be re-arranged as 0.3 x 10^9 meters per second.
Therefore as 0.3 meters per nano-second.
[As a personal aide-memoir, this is approximately the length of your forearm, 1 foot, from elbow to wrist.
Check it out for the sum: Forearm goes in to 2 meters approximately 6 times looks good!]
A good technique to examine whether or not youre in the best ball park, is to recall that 1 meter =~ 3.25 ft.
So, the given distance 6.5 ft =~ 2 meters.
So, your goal time period may be expressed as (2 meters / 0.3 meters) nano-seconds.
Viz. 6.67 nano-seconds.
[Using the more accurate (definition) value for c of 299,792,458 meters per second, together with the more accurate conversion factor of 0.30480 for feet to meters, will yield 6.608572 nano-seconds.]
This may be re-arranged as 0.3 x 10^9 meters per second.
Therefore as 0.3 meters per nano-second.
