Question

2.4
The time taken by an electron to completo one rotation about its nucleus
is 0.5x10-seconds. Convert it into minutes, hours and microseconds.
(Ans. 8.333x10 "1 minutes, 1.388x10-22 hours,
0.5x10-12 microseconds))​

Answer 1

Explanation:

To convert second into minutes we need to divide the seconds by 60 because

1 minute = 60 seconds

So,

0.5 x 10^-18 seconds/60 = 8.333 x 10^-21 minutes

Now, to convert 0.5 x 10^-18 seconds to hours, we need to again divide the minutes value by 60 because

1 hour = 60 minutes

So,

8.333 x 10^-21/60 = 1.388 x 10^-22 hours

To convert seconds to microseconds, we need to multiply the seconds value by 10^6 because

1 second = 10^6 microseconds

So,

0.5 x 10^-18 x 10^6 = 0.5 x 10^-12 microseconds
