Through the equation F = BIL sin(x) since the current is the same on each side, the force incoming is the same as the force outgoing hence the resultant force will be zero?

So the net flow of current is 0A as shown by the diagram there are two arrows in the opposite direction of magnitude 5.0A?

Homework Statement 2. Homework Equations [/B] F = BIL sin(x) The Attempt at a Solution This isn't homework its a practice question so I have looked at the answer and its 0N however I do not understand why it is 0N. I have tried resolving the magnetic flux density so its perpendicular to the...

Well just like photons when they enter the body they still irradiate human tissue, but what makes them good is the Bragg peak they deliver there maximum dose at once and hence they are stopped and do not further irradiate human tissue on exit. They are much more controlled because they are...

Hi, I'm trying to think of a better alternative particle to protons for cancer treatment and was wondering if someone could put me in the right direction, do any other particles have properties such as the Bragg peak that would make them a good contender?

I don't see anything wrong with the signs in the second equation could you explain further also how would I obtain V?

1. Homework Equations [/B] P = mv The Attempt at a Solution [/B] VCos(30) + 0 = nCos(60) + 2Cos(20) VSin(30) + 0 = nSin(60) + 2Sin(20) where I let n = any speed, I'm not sure if my attempt at the solution is correct.

Hi, I'm aware that charge, baryon number, lepton number, energy and momentum must be conserved. Yeah I should have asked why these laws must be obeyed.

Why is it that when energy is converted into mass we must make equal amounts of anti matter as matter during pair production?

He used it to explain how wavelength and wave speed change yet the frequency stays the same when light enters a medium. He stated frequency is energy and energy is conserved.

I was told by my physics lecturer energy is the same as frequency, if this is not the case what is energy represented by in a wave?

Why is it that the fundamental harmonic is louder than rest? If energy is the same as frequency surely the greater the harmonic the louder it is. Also what does amplitude represent in waves?

Hi I was told by physics lecturer that both the wave speed and wave length of light changes when it enters a medium, however I questioned this stating that if both wave speed and wave length changed then frequency must also according to the formula c = fλ. He stated that "frequency is energy...

Hi this formula assumes that the wavelength of the two waves are the same, how would I deal with calculations where both wavelengths are different?

Would you be able to further explain what you mean by the phase varies with position and time? What is the phase different relative to?
