thats where i got my equation from. d = 1/2at1^2 therefore, t1 = sqrt(2d/g) and t2 = d/v(sound) t1+t2=t(total) therefore, (d/v)+sqrt(2d/g) = t(total) it's the rest of it i get messed up on, I've tried it severl times, and it appears you are hinting at this equation, a little insight?
i need help with this problem. I've tried for a while now and it is driving me crazy! I've tried about everything including using what little calculus i remember from last year! please help! the problem is: you are standing on a cliff and you drop a rock straight down, neglecting air resistance...
I am trying to be as general as posible. Assuming the two wires are the same, and there is no power lost at the source or at the reciever. Just a basic data stream that travels from point A to point B.
Again, Thank you for help.
Can anyone give me a good general formula or expanation for the diference in attenuation in a data signal in a network over a 500 and a 5000 foot cable?
Help would be much appreciated. Thanx!
I'm sorry, I didn't specify. I want to build a small, remote-controlled, low-speed, levitating machine. maybe these specifications will give me more results.
Thank you for any help.
I am looking into building a hovercraft, but i have virtually no idea where to begin. I could use a bit of help. Perhaps something that uses magnets...
Thanks for any help.
Does anyony know of a good, cheap (Perhaps Free :biggrin: ) book that will teach me the basics of quantum field theory. I am a very new beginner, so I will need something simple please.
thanks.
Can anyone tell me why, or why not,.\bar{9} is equal to one?
Also, if anyone cares, I can prove that \frac{0}{0} = any number.
If 0 times any number is equal to zero, then zero divided by zero is any number.
