I have a question that I am sort of stumped on.
a) A reaction is essentially complete in 5.0 x 10(to the power of-4)seconds. If one millisecond is equal to 10(to the power of negative -3) seconds, how many milliseconds will the reaction take
ANSWER- I got 5 x 10(to the power of -1) or 0.5 ms. Is this right? I have no idea how i got it.

-
reaction-time = 5.0 x 10^-4 seconds
1 second = 1000 milliseconds,
SO,
reaction-time = 1000*(5.0 x 10^-4) = 5 x 10^-1 milliseconds >============< ANSWER
OR,
Reaction-time = 0.5 milliseconds >=============================< ANSWER

-
5.0 x 10(to the power of-4)seconds=.0005
10(to the power of negative -3) seconds=.001
.0005 is 1/2 of .001 so the reaction takes .5ms
10(to the power of negative -3) seconds=.001
.0005 is 1/2 of .001 so the reaction takes .5ms
