The second hand goes around once.
90 degrees. (360 degrees in a clockface, takes 60 seconds to cover all of them. So the second hand covers 6 degrees per second (360 divided by 60). Now multiply 6 degrees per second by 15 seconds - i.e 6 x 15 = 90
The second hand on the clock circles 420 times in 7 hours.
Once per Minute -or- 60 times per hour 60x24 1440 Times a day (Also how many minutes that are in a day)
Once around in every minute, sixty minutes in an hour, and 24 hours in a day, so 1 X 60 X 24 = 1440.

The hour hand goes around the clock twice in one day, the minute hand goes around 24 times, and the second hand makes 1440 revolutions. So, in total, all three hands go around the clock a combined total of 1488 times in one day.

We're assuming that you mean the "hands" on a clock. Short hand . . . the "hour hand", goes all the way around in 12 hours Long hand . . . the "minute hand", goes all the way around in 1 hour On some clocks, there's another long hand that you can see moving. That's the "second hand". It goes all the way around in 1 minute, 60 times in 1 hour.

On a scale of 1-10 ; -10. It's harmless as second-hand.
Second hand marijuana smoke is 30 times as potent as being exposed to the initial dose of smoke.
Yes.
Second hand smoke
I'm assuming your question is about that of second hand smoke.Yes they can pick up second hand smoke in a drug test, however they are able to distinguish it from first hand smoke.
The angular displacement of the second hand in 5 seconds can be calculated as 30 degrees per second times 5 seconds, which equals 150 degrees.
