Do you think that as our universe evolves that perhaps a planet could be made by super dense elements, even denser than Plutonium and Uranium? Could a sun gain enough energy to begin fusing iron as it's main fuel source, or will the universe grow dark once all the lighter elements have been fused above the level of iron?

can anybody explain dimensional analysis?

could u also answer this question?

The position of a particle moving under uniform acceleration is some function of time and the acceleration. Suppose we write this position s = k * a^m * t^n, where k is a dimensionless constant. Show by dimensional analysis that this expression is satified if m = 1, and n = 2. Can this analysis give the value of k?

thanks

Surely there is room for them to crawl through there, but I doubt they're likely to find a little hole. I think they're far more likely to come in through the door when people go in & out. But my wife says she thinks they sniff out & find those little screen holes & little cracks below the door & other such little places ... Do you think that houseflies have the talent to find their way in through little holes in the window screens?
