Discontinuous voltage graph for bullet going through metal coils

In summary, the conversation discusses the discontinuity of the graphs for ##V_1## and ##V_2## where they cross the time axis. It is suggested that this is simply a drawing issue and not related to the physics, as the voltage induced is proportional to the change in the B-field through the loops. It is recommended to ask a TA or professor informally if this confusion is affecting the ability to solve the homework problem.

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!

1. What is a discontinuous voltage graph?

A discontinuous voltage graph is a graph that shows changes in voltage over time, where there are abrupt changes or gaps in the plotted data. This can occur when there are sudden changes in the electrical circuit, such as a switch being turned on or off.

2. How does a bullet going through metal coils affect the voltage graph?

When a bullet passes through metal coils, it can cause disruptions in the electrical circuit, resulting in changes in voltage. This can be seen as spikes or dips in the voltage graph, depending on the direction and speed of the bullet.

3. Can the discontinuous voltage graph be used to determine the speed of the bullet?

Yes, the discontinuous voltage graph can be used to estimate the speed of the bullet. By analyzing the time intervals between the voltage spikes or dips, and knowing the distance between the coils, the speed of the bullet can be calculated using the formula speed = distance/time.

4. Are there any other factors that can affect the discontinuous voltage graph in this experiment?

Yes, there are other factors that can affect the voltage graph, such as the material and thickness of the coils, the type of bullet, and the distance between the coils and the bullet's entry point. These factors can alter the magnitude and shape of the voltage spikes or dips.

5. What are the potential applications of studying discontinuous voltage graphs in this experiment?

Studying discontinuous voltage graphs can provide valuable insights for forensic investigations, such as determining the direction and speed of a bullet, and reconstructing the sequence of events in a crime scene. It can also be applied in industries that involve high-speed projectiles, such as military and aerospace, for quality control and performance testing purposes.
