Hi. I was just wondering if the natural log of the square root of 2 - the natural log of the 4th root of 2 could be simplified?

ln [(square_root_sign) 2] - ln[ (4th_root_sign) 2]

Thanks a bunch!

anyone know about how big a Neodymium magnet i would need and what shape to hold the spring latch of a briefcase closed. I need to be able to pull the latch open. I

I was thinking something about the size/shape of a penny. Distance is about 1/4" It's a prop for a show so it doesn't have to work great. i'm going epoxy the magnet to the inside of the case and close the latch which is broken to hold the case closed.

I have to find the percent error for this lab at school, but I can't find the absolute density for Carbon Dioxide. I've tried everything from contacting friends to Googling it. This is my last resort. If you found the density on a site, could you please list the site as one of your resources? Thanks.

I heard on Oprah a lady that went to space said is smelled like burnt cookies but my husband doesn't believe it and said it is IMPOSSIBLE for space to have any smell at all. He said there were no particles or something like that. Can space have a smell?

I was listening to the radio today and the host was talking about a small spot on Jupiter and how scientists are interested in it because it is changing color. He said the spot is the size of Earth. How weird is that to think about?

A 7.50 kg block is resting on a horizontal surface, and is connected to a 5.50 kg mass suspended from a string passed over a frictionless pully. The surface is smooth, with no friction.

Would the tension on the string be 53.9 N?

I'm also suppose to find the tension of the string if the coefficient of friction is 0.190 on the surface, I have no clue on how to find that..A little help maybe?
