Discontinuous voltage graph for bullet going through metal coils

Click For Summary
The discussion centers on the discontinuous nature of voltage graphs V1 and V2 as they intersect the time axis in the context of a bullet passing through metal coils. Participants suggest that the discontinuity appears to be a drawing issue rather than a physical phenomenon, as the induced voltage should be continuous based on the change in the magnetic field. The confusion regarding the graphs does not seem to hinder the ability to solve the homework problem but is more of a curiosity. It is recommended to seek clarification from a teaching assistant or professor if needed. Overall, the focus remains on understanding the graphical representation rather than the underlying physics.

However, dose anybody please know why the graphs for ##V_1## and ##V_2## are discontinuous where they cross the time axis?

Many thanks!

It only looks like a drawing issue, not something to do with the physics. The voltage induced is just proportional to the change in the B-field through the loops, which is certainly continous in the real world. Is this confusion affecting your ability to solve your homework problem, or just a curiousity at this point?

If (b), I would recommend that you just ask a TA or the professor informally when you next see them.

Thanks for your help @berkeman ! Just (b) at this point, but it does sound like it drawing issue as you mention.

Thank you!
 
If have close pipe system with water inside pressurized at P1= 200 000Pa absolute, density 1000kg/m3, wider pipe diameter=2cm, contraction pipe diameter=1.49cm, that is contraction area ratio A1/A2=1.8 a) If water is stationary(pump OFF) and if I drill a hole anywhere at pipe, water will leak out, because pressure(200kPa) inside is higher than atmospheric pressure (101 325Pa). b)If I turn on pump and water start flowing with with v1=10m/s in A1 wider section, from Bernoulli equation I...
