he was jokingly attributing his success to his somewhat lower libido... It was within the last ten years, I believe, that this Nobel prize winner said this, certainly within the last fifteen. I believe it was chemistry or physics, I just can't figure out who.

please explain to me how to do this problem, i dont get it :(

a sample of hydrogen gas has a volume of 145 mL when measured at 44*C and 1.47 atm. what volume would the hyrogen sample occupy at STP?

Is it hard and can someone give me a good idea of what to expect..If this helps any, I actually find calculus fun!

--An 80.0 N box of clothes is pulled 22.0 m up a 30.0° ramp by a force of 115 N that points along the ramp. If the coefficient of kinetic friction between the box and ramp is 0.22, calculate the change in the box's kinetic energy.

-- A 103.0 N grocery cart is pushed 12.0 m along an aisle by a shopper who exerts a constant horizontal force of 40.0 N. If all frictional forces are neglected and the cart starts from rest, what is the grocery cart's final speed?

i've done some work for each but the online worksheet keeps on telling me my answers are wrong. could somebody please step by step write out how to do these problems (w/ numerical values if possible)

do some of you believe that UFO's are REAL as much as you believe god is real. i hear people saying the universe is endless, we don't know that but that is what we believe. so if the universe is trilllions, beyong trillions of miles long or more, then some people say that it is impossible that only EARTH has living creatures. some people even say there might be living creatures on the other side of the universe questioning the same thing we are questioning. are we alone? personally i don't beleive in ET.
