You are working in a factory that produces long bars of copper with a square cross section. In one section of the production process, the bars must slide down a plane inclined at an angle 0 = 23.5° to the horizontal. It has been found that the bars travel with too high a speed and become dented or bent when they arrive at the bottom of the plane and must be discarded. In order to prevent this waste, you devise a way to deliver the bars at the bottom of the plane at a lower speed. You replace the inclined plane with a pair of parallel metal rails, shown in the figure below, separated by a distance = 1.80 m. R B m The smooth bars of mass m = 1.00 kg will slide down the smooth rails, with the length of the bar always perpendicular to the rails. The rails are immersed in a magnetic field of magnitude B, and a resistor of resistance R = 1.60 ₪ is connected between the upper ends of the rails. Determine the magnetic field necessary (in T) in your device so that the bars will arrive at the…

Beams of electrons and protons, both traveling at almost the speed of light collide. The electrons and protons are in bunches 2 cm in length in two rings of 300 m circumference, each of which contains one bunch. Each bunch contains 3 × 1011 particles, and the circulating frequency is 106/ sec for each beam, so that 106 bunches collide with each other per second. Assume that the particles are distributed uniformly over a cross sectional area of 0.2 mm2 and that this is also the area of the intersecting collision region.(a) Determine the luminosity.(b) If the cross section for collisions is 10 µb, determine the number ofscattering events that would be observed in a counter totally surroundingthe intersection region.(c) Find the average flux of electrons.(d) If the beam of electrons scatters from a stationary target of liquid hydrogen (density ≈ 0.1 g/cm3) 2 cm long, rather than with the circulatingproton beam, find the number of scattering events and compare to theanswer of (b)?

I need help with this question. I'm attaching the data tables and graphs. Please explain step by step. Question: The permeability constant for a vacuum, u0, has a value of 4pi x10-7 Tm/A. Assuming the equation B=u0nI applies to the slinky. Obtain a value of pi from your graphs and compare with the 'theoretical' value.
