Is it not possible that superstrings started life off.

is inflated at a rate of 14cm/s
(a) Express the radius r of the balloon as a function of the time t (in seconds). r(t)=t/14cm/s

(b) If V is the volume of the balloon as a function of the radius, find V r.

4/3pi(t/14cm/s)

not sure if that is right? do I divide t by the inflation rate?

My concern is that it's a hoax. Ever hear of the Beavis and Buthead UFO hoax? You throw a spinning garbage can lid through the air about 50 feet away, and then take a picture of it. LOL.

I hoping there is an easy answer to this question. I am starting a basment remodel on my single story home. The three 2x10's are currently supported by two Jack posts 8 feet apart. I would like to have a clear span. Is it possible to span this 25 feet with an I-beam supported by Jack posts on the ends? And if so, how big? I have 8 foot ceilings so I can afford to give up some head room for a beam.Thank you for your help.
