How many miliseconds are there in a week?
7 days * 24 hours * 60 mins * 60 seconds * 1000 milliseconds is 604,800,000 milliseconds.
How many days in a millennium?
365 x 1000 = 365,000, but you need to add extra days for the leap days:
25 leap days will occur during centuries whose final year is evenly divisible by 400 (e.g. 1901-2000 had 25 leap days); otherwise 24 leap days will occur (e.g.1801-1900 had 24 leap days).
Therefore 10 centuries will include 8 or 7 centuries with 24 leap days and 2 or 3 centuries with 25 leap days respectively.
24 x 8 + 25 x 2 = 242 and so 365,000 + 242 = 365,242, or
24 x 7 + 25 x 3 = 243 and so 365,000 + 243 = 365,243
How many minutes are in 1 year?
365 days * 24 hours in a day * 60 minutes in an hour = 525600 minutes
527040 for leap year
60 mins. times 24 hrs. equals 1440 mins. times 365 days. equals 532896 mins. The total minutes in one year.
How many seconds equal 1 nanosecond?
1 nanosecond = 10-9 sec = 0.000000001 sec = 1 billionth of a sec.
(Roughly the time it takes light/radio to travel one foot.)
Why are there 132 minutes in an hour 12?
There are not 132 minutes in an hour. There are only 60 minutes in one hour.
How fast is one one hundredth of a second?

Sketch of graph of pendulum on moon?
The question as asked is tough to answer without some assumptions... The question implies that a comparison is being made to the action of the same pendulum on earth. With that assumption... The graph I assume has time on the x-axis and a form of pendulum oscillating measurement (such as height or back (-1) to forward (+1) ) on the y-axis. The period ( time from peak to peak on the y-axis ) of the pendulum on the moon compared to the same on earth will be 6 times longer assuming that gravity on the moon is 1/6th that of earth. The reason why the period is longer is that the acceleration (gravity) on the moon is much less. This causes the pendulum on the moon to move back and forth less quickly.
What does the abbreviation of PM mean?
PM is an abbreviation for Post meridiem; Latin for after noon. Incidentally, AM stands for Ante meridiem - before noon.
How many milliseconds are there in 3.5 seconds?
