A 5.8-mm-diameter proton beam carries a total current of 1.5 mA . The current density in the proton beam, which increases with distance from the center, is given by J=Jedge(r/R) , where R is the radius of the beam and Jedge is the current density at the edge.
Part A: How many protons per second are delivered by this proton beam?
Express your answer using two significant figures.
N = ??? protons per second
Part B: Determine the value of Jedge.
Express your answer to two significant figures and include the appropriate units.

You notice a very one-dimensional-thinking snail crawling along one rail of a railroad track. naturally, you remove it to a safer place. but before you do, you observe it as it moves from position xi = -92.9 cm to position xf = -64.9 cm along the rail, as measured from a point where one rail abuts the next. what is the snail\'s displacement δx in centimeters?
