There's several ways to approach the problem, depending on what kind of year you're interested in. If it's a calendar year, then an exact answer is possible: each day is 86,400 seconds and each year is 365 days (except for a leap year, which is 366). This gives a result of 63,072,000 seconds in two years, 63,158,400 if one of them is a leap year: obviously both can't be leap years at the same time. The calendar year is the year to watch if you're interested in actual timekeeping. For example, if you start a timer at midnight between December 31 and January 1 one year, and stop the timer two years later, the above answer is the one you'd end up with (though the timer would probably overflow by then). You could also be interested in two years from an astronomical point of view: how many seconds it takes for the Earth to make two complete revolutions around the Sun. There's slight ambiguity in what we mean by "complete revolution," but one common measure is the sidereal year - a complete revolution from the point of view of a hypotherical observer on a distant star. It is approximately 31,558,149.54 seconds long, making the length of two years slightly over 63,116,299 seconds.

You haven't given us any information from which to calculate that speed. As far as we know from the question, the object isn't moving at all.
This question doesn't make a lot of sense. Maybe something is missing? To convert seconds to metres per second you would need to divide the metres given by the number of seconds used. If all you have is seconds, and no distance, then you are stuck. Metres per second is a measure of speed and seconds is a measure of time. Speed=distance/time. So divide your metres by your seconds to get metres per second.
Each degree is equal to 60 minutes, each minute is equal to 60 seconds; to convert seconds to minutes, divide the seconds by 60 and add to the minutes. Ex. (Assume the asterisk (*) is a degree sign) 51* 43' 20" 51* + 43' + (20/60)' 51* + 43' + (1/3)' Answer: 51* 43 (1/3)' Hopefully this is answering the question you had. If you want to convert Minutes and seconds into decimal degrees, use either formula below: ((Seconds/60) + Minutes)/60 + Degrees or Degrees + (Minutes/60) + (seconds/3600)
The whole point of a pendulum is that is swings back and forth. It does not travel at constant angular velocity: the angular velocity is zero at the two ends of its arc and it reaches a maximum when the pendulum is vertical. Consequently there cannot be a sensible answer to the question as asked.The average angular velocity, which is an entirely different measure, is 45 degrees per second.
Oh, dude, like, one trillion years is a looong time. So, in one trillion years, there are 31,536,000,000,000,000 seconds. Yeah, that's a lot of seconds. So, if you ever need to know how many seconds are in a trillion years for some reason, now you know!
