What's the answer?

Question

How many seconds are in a year?

Answer 1

12
January 2nd, February 2nd, March 2nd, etc

Answer 2

This hardly seems grounded on anything.
31,556,925.9936 (Calculated by other means)
31,415,926.535897932384626433832795 (pi * 10^7)

When you approximate the number of seconds in a year you can look it as
[number of days in year] * [seconds in a day]

or you can:
Calculate the circumference of the earth's orbit and divide by the
speed of the earth's rotation. Like this:
Radius of Earth's Orbit (r) = (1) Astronomical Unit


circumference = 2*r*pi
2*1*pi = 6.283185307179586476925286766559 (The circumference = 6.28 AUs)

An AU is approximated by 149,600,000 km

convert AUs to km by multiplying (6.283185307179586476925286766559 * 149600000)
= 939964521.95406613694802290027723

The earth's speed is estimated to be 29.7859 km/s

The number of seconds in a year equals:
circumference / Earths_speed
939964521.95406613694802290027723 / 29.7859 = (31557365.127596149082217522394059)

The number of seconds = (31557365.127596149082217522394059)

This is another dandy estimate. However the solution is only as good
as the samples that support it.
(see http://www.campusprogram.com/reference/en/wikipedia/e/ea/earth_1.html )

Indeed there are better ways like actually calculating the
circumference of the ellipse that the earth's orbit is.

But then we are still limited by the estimates given by samples (or
other calculations). Otherwise we are caught in a case of
merrygoround mathematics. By this I mean if the speed of Earth
determined by using the circumference then how do we know what the
circumference is. And if the circumference is determined by using the
speed then how fast is the Earth traveling.

Clearly we need a better way of determining how many seconds are in a year.

Answer 3

Multiply

365*24*60*60 = 31,536,000 seconds

Ofcourse in a leap year add another 86,400 seconds.

Thus a leap year has 31,622,400 seconds

However, if it is a trick question, you have 12 seconds in a year: 2nd of January, 2nd of February...... etc upto 2nd of December

Answer 4

seconds?
12

Answer 5

12. If you're counting the second days of each month; 24 if you include the twenty-second day of each month. Or if you want the amount of seconds time-wise, there are 315,636,000 or 316,554,00 if it's a leap year.

Answer 6

if we accept a standard year as 365days of exactly 24 hours each (which they are not) then there are 31536000 seconds in a standard year and 31622400 seconds in a leap year.

i am not certain of the actual length of a day.... i think it is in the region of 24 hrs and 15 mins.....


OR we could just say that there are 12. since there is a 2nd in each month of the year....LOL good one!!

Answer 7

Theres a second (2nd) in every month so 12 in a year.

Answer 8

To be precise there is 315,360,00 in a year!

How?

You take 60min X 24hours= 1440
then you take 1440 X 60sec=86 400
Then you take 86400 X 365days= 31536000

Or

There can be 12 2nd's in a year, since there is 12 months!!!

There you go!!!!

Answer 9

31579200 seconds

Answer 10

24.. 2ND'S
31536000.... SECONDS IN AN ORDINARY YEAR
31622400 .... SECONDS IN A LEAP YEAR
