There we go! That let me get the entire problem done! Thanks again!

Ahh that makes sense! Thank you very much!

Can you explain the wedge part a little more? I am a little confused by what you mean.

Homework Statement A proton (q = 1.6 X 10-19 C, m = 1.67 X 10-27 kg) moving with constant velocity enters a region containing a constant magnetic field that is directed along the z-axis at (x,y) = (0,0) as shown. The magnetic field extends for a distance D = 0.79 m in the x-direction. The...

In my physics class we are learning about electric potential right now. I know electric potential is electric potential energy with the charge divided out. I am curious if the potential difference is just the difference between the two points. My thinking is we have point A, and B. The path...

Homework Statement y = c1e3xcos(2x)+c2e3xsin(2x)+c3+c4x Homework Equations Differential Equations. The Attempt at a Solution I am having trouble what the roots are for the c3, and c4 parts. I know they are a repeated root, but is it just k= 0? It seems like it would work, but I...

Homework Statement y = c1e3x+c2xe3x+c3e2xsin(x)+c4e2xcos(x) Homework Equations Differential Equations. The Attempt at a Solution I have the roots of k=3, k=3, k=2+i, k=2-i. Now I am just stuck on how to put the roots together to get the original equation. I am just stuck on the complex...

I am having some conceptual trouble in my physics II class right now. The book is not that good, and I am looking for a website that has good conceptual practice. Do any of you know a website like this? My professors conceptual quizzes are killing me right now, and it would be much appreciated.

Homework Statement http://imgur.com/VzZjSEH I took a screen shot so I did not leave anything out. Homework Equations Surface area, and volume of a sphere. The Attempt at a Solution I am trying to find the linear charge density from the charge volume density. I got it explained...

Homework Statement http://imgur.com/sg8czUR An infinite sheet of charge has a charge density of σ= -2.1 uc/m2. (uc is micro-coulombs). The inner edge of the infinite conductor slab is 2.6 cm away. The outer edge is 4.2 cm away. The conductor slab has a charge density of σ= 74 uc/m2. What is...

Ah thank you. Things online told me strain is dimensionless, but it was in m/m. Thank you!

Homework Statement Here is a picture of the problem: http://imgur.com/Ldw1fUF Make sure to click on the picture to make it bigger!Homework Equations The strain/hooke's law equations.The Attempt at a Solution I have this for two parts. The second part is the deformation which I got right. I am...

They are N/m^2. I used an online converter to check, so I confused about what I did wrong.

Homework Statement In a prismatic bar (same cross sectional area throughout the entire length), the load applied to both ends is 100 N causing the member to be in tension. If the cross sectional area of the member is 5 cm2. What is the normal stress in the in kPa? Homework Equations...
