Two charges, each with a value of +q are separated by a distance of l m. The resultant electric field and the potential measured at a point P a distance l/3 m from the left charge, are, 10 N/C and 2 V, respectively. What are the values of the distance l and the charge q?
Line Spectra and Energy Levels
I'm having trouble understanding the problem. What do you do? I'm so lost. What formula do I get to get eV? I've written all the KNOWNS that I know. I'm looking for someone to show me how to do this one, so I can do the rest of my homework.
Stopping Power for an Electron
The provided answer to #7 is 0.0383Mev/cm. I have n=4.7x10^29 and I=87.2eV for #7 but I missing something in the translation of equation and conversions. Please see the attached file for the two problems with equation.
Fission is a process in which the nucleus splits into two parts that are roughly the same size of the original nucleus. In fusion, two nuclei fuse, or combine, to form one nucleus. These reactions seem to be opposite to each other and yet both release large amounts of energy. Explain why this is not a contradiction.
Accelerated particles: maximum kinetic energies in a cyclotron
If a cylcotron is capable of accelerating protons to 100MeV, maximum. What are the "approximate" maximum kinetic energies to which deuterons and alpha particles can be accelerated? I feel its just a simple proportional mass and velocity difference but I wonder if the difference in charge in cylotron is also considered?
As 1kg of 235U decays calculate the temp change of the mass.
Assuming no energy escapes, find the approximate temperature rise of 1kg of 235U over 1year from decay. Note: No tables or attachments for this problem.
I am having trouble deciding which formula to use for this particular problem. A nicket target (Z = 28) is bombarded with fast electrons. The minimum electron kinetic energy needed to produce x-rays in the K series is most nearly what?
Synchrotron for fixed target collisions
To achieve an energy of 20TeV, each of the SSC main rings contains approximately 4000 dipole magnets, each 16m long with a field of 7T. This means that over half of the 60mile SSC tunnel is taken up by dipoles. if you were to build a single synchrotron for use in fixed-target collisions of equivalent energy in the center-of-ma ...continues
Motion of a charged particle in a magnetic field.
I cannot figure out what equations to use or how to set up the following problem. It just seems like there is some data missing that i need. Any insight as to where to start would really help! A radioactive source emits alpha-particles with kinetic energies of 4MeV. What must be the value of an applied magnetic field so th ...continues
I am confused as to how to apply the 10% accuracy in the attached problem. Also, I am not sure how to set up the problem just to get the minimum value.
