I went back to class today and I figured it out thanks alot. I just integrated it wrong, I had to do some trig subsitutions. (that is where the extra R came from)
Homework Statement
Halliday and Resnick edition 7 chapter 22 number 29
In Fig 22-45, positive charge q = 7.81 pC is spread uniformly along a thin nonconducting rod of length L = .145m. The y distance between the point and rod is R = .06m. What is the magnitude and direction of the...
I am a senior in high school right now and I am just thinking about if I major in physics would it be possible for my to get a job working outdoors, that is semi related to physics?
Yea I am not really worrying about it, I am just trying to gather all the information possible. Plus it is really interesting thinking about what my life is going to be like.
Yea geophysics is what I have been looking at a lot lately, I just can't find any good schools close to home (pennsylvania) with geophysics (didnt get accepted to psu main). I am thinking about going to millersville for my undergrad physics degree.
"Except for some chemical engineers i think...
I am a HS student looking to major in Physics in college. After reading some posts I am wondering what kind of jobs there are with a B.S physics. Could I work in the oil drilling or nuclear field? I am also thinking of maybe majoring in Geology, what do you think a bout a geology major?
What do you mean by homeless. I am in HS right now and looking to major in physics, is pursuing a physics major not a financial secure major? I thought that majoring in physics would open up many good careers?
This is a good problem. Does the mass break apart equaly because I keep getting half of the KE (187500J) I am doing .5(50/3)(150)^2. Anyone have any input
Not 100% sure but did this class today
For b) you have to do conservation of energy .5mv^2+mgh+(work done by friction)= 0. From there you should have enough informationto solve for (work done by friction).
You use the cos of 0 and 180 because that is the angle between the Force and displacment. This is the definition of Work. W=Fdcos(angle). This would make the work either negative or positive. If one moves an object against a force(gravity) then there would be a negative Wnet. If one moves...
Right now I am in AP physics in High School, while also taking calculus and I need some assitance on when and how to apply the calculus (once I know to do calculus I can go from there)
Example
If Potential Energy is 5x^2+3x+7 what function is the force.
- I know you have to take...
