72 is "seven to the second power" or "seven to the power two" or "seven squared", and when it is calculated it is "forty nine".

Calculated TimeThere are 259,200 seconds (4320 minutes) in 3 days.Riddle answerIf this is a trick question, then there is only one "second" in three days. The first day, the SECOND day, and the third.259,200 seconds.
How is the unit lightyear measured?
It's calculated, not measured. It's the speed of light ... 299,792,458 meters per second ... multiplied by the number of seconds in a standard year.
What does the phrase per second per second mean?
per second per second is taken with the context of how an object is changing its acceleration. An object accelerates by speeding up or slowing down. If an object speeds up, it could speed up at a rate of 5 meters per hour, let's say, every second. So after one second, its speed is 5 mph; after two seconds, its speed is 10 mph and so forth. If an object's speed is increasing at 5 meters a second, then its speed is 5 meters per second the first second; 10 meters per second the second second and so forth. We would say the object's acceleration is 10 meters per second / per second.AnswerIt has to do with speed,the time an object falls from a given height is calculated in seconds per second( it fell in less than a second)
A ball is dropped off a ledge How far does it fall in the second second?
It all depends on the weight of the ball but if a tennis ball was thrown it would travel 2 1/2M in 2 seconds but cannot be calculated like this because the further the ball falls the more speed it gains. However there is a trick to this question because the 2nd second is only one second itself. making the answer 1M and 10CM !
