Thank you so much for the reply! I am sure I want to go to graduate school in Meterology right after graduating, that is if I can get in. I am hoping around 3.2-3.3 gpa is good enough.

Hi everybody. I am currently a junior at a college in Maryland. I have finally realized that I want to be a meteorologist or atleast something similiar. I am majoring in physics and I have taken several chemistry classes. I have also taken 1 programming class and 1 statistics class. I really...

is it proportional to a^3 or 1 / a^3 . thanks!

Hey, this isn't a homework question but is more for help with a project. For our D.E. class we decided to model a building while it is being impacted by an earthquake. We are going to make up a building to use. Anyway, we are having trouble relating the earthquake to the building. We know that...

That works out good. Thank you for your help!

e^(3*(1-x)^.5) = (4-2x)/x thank you

A solid steel ball is hung at the bottom of a steel wire length 2 meters and radius of 1mm. The ultimate strength of steel is 1.1 X 10^9 N/m^2. What is the mass of the biggest ball the wire can bare. This seems like a pretty straight forward question. I am guessing the 2 meter radius doesn't...

Thank you very much! I still have a lot to learn but this is very interesting! Thanks again.

In Einstein's view of a static universe what would happen if some mass turned into radiation? I am thinking that since the density would decrease then the universe would expand since the cosmological constant would stay the same. Would it change?

I need to show that ds^2 = dx^ + dy^2 + dz^2 is the same as ds^2 = dr^2 + r^2 (dpheta^2 + sin^2pheta*dphi^2) ... I know that I need to use x = r sin pheta cos phi y = r sin pheta sin phi z = r cos pheta I am confused but I think I have to take the derivitive of something. Do I...

Last question I promise,,,, A uniformly charged disk has a radius of 2.5 cm and carries a total charge of 4*10^-12C. Find the electric field on the x-axis at a distance of 20cm away. I used the equation: Ex = (sigma/ (2*Eo)) * (1 - ( 1/ sqrt( ( R^2/x^2) + 1)) this is what i...

Thanks a lot, i understand it better now!

Each quare centimeter of the surface of an infinite p;ane sheet of paper has 2.5 X 10^6 excess electrons. Find the magnitude and direction of the electric field at a point 5 cm from the surface of the sheet, if the sheet is large enough to be treated as an infinite plane. This is an odd...

Help Determining the Activation Energy Reply to Thread Ahh, yes that's what I was missing. Thank you very much for helping me out!

I fixed the format a little, sorry about that. This was the exact question given. The answer given is 30.3 Joules. I have tried everything and can't get an answer close to it. I know that we are supposed to use Arrenhuis's equation and something about a slope of a graph. I just can't put...
