thanks to the both of you for your help. i was able to figure it out.. silly mistake. =) night!

hello all. I'm trying to figure out this problem and it's bugging me because it's soooo simple yet i keep getting the wrong answer. here's the problem: If 1.00 mol of carbon dioxide gas at 350 K is confined to a volume of 400 cubic centimeters, find the pressure of the gas using the...

hi! I was wondering if someone can help me with this physics probelm: A single ice cube with mass X g floats in a glass completely full of Y cm^3 of water. You can ignore the water's surface tension and its variation in density with temperature (as long as it remains a liquid). What...

got it.. i WAS getting the area wrong.. i was imputing it incorrectly into the calc. thanks so much for your time and patience!

yes, it is online homework and that is the complete problem except "x" and "y" there are real numbers. so instead of multiplying by 4 i just divided x by two before I plugged it into the equation.

regarding the equation that I am using (p = F/A), does that even look like the correct equation I need to solve this type of problem?

My final equation looks like this: (Y kg)*(9.8 m/s^2) / (pi)*(r^2) = p (pascals)

Why is the equation being multiplied by 4?

that's right, i should only consider the area of one circle. that "2" in front of pi r squared was a typo... =) I've been trying to calculate it assuming it's one circle but I'm doing something wrong. =/

Hello! I was wondering if you could help me with a homework problem: The piston of a hydraulic automobile lift is X meters in diameter. What gauge pressure, in pascals, is required to lift a car with a mass of Y kg? I know that a piston is a cylindrical shaped apparatus - however I...

thanks! i knew it was a concept I had studied a few chaptes earlier but it completely slipped my mind. that's right, index of refraction depends on c and hte speed of light in that particular medium! =)

slit diffraction in water? Hello! I'm having trouble answer this homework problem: Suppose the entire apparatus (light of wavelength X nm from a distant source is incident on a slit Y mm wide, and the resulting diffraction pattern is observed on a screen Z m away) is immersed in water...

okay.. my last comment.. ignore it, i wrote too soon! it was my fault i kept entering the wrong numbers in my calculator. thanks so much!

Thanks, that really clears things up, however I'm still confused a little. So by looking at the formula that equals lambda, I would assume that when m = 0, is when lambda is the greatest right? however the answer i am getting is still incorrect. Am i not understanding you correctly?

hii guys! I'm having trouble with a homework and I was wondering if you could explain something to me. Here's the problem: Two radio antennas A and B radiate in phase. Antenna B is a distance of X meters to the right of antenna A. Consider point Q along the extension of the line...
