1. What was discovered that provides evidence of a cause-and-effect relationship between the
number of wire coils on an electromagnet and magnetic fields?
2.
Using the data you collected, predict how many paper clips the nail could pick up if 400 cm
of wire is wrapped around the nail
3.
What other questions would you like to investigate now that you have examined your data
about objects interacting through the electric and magnetic forces? *Have some fun and try
to test these on your own!

the duration of a photographic flash is related to an rc time constant, which is 0.100 μs for a certain camera.

  distance on the y-axis and time on the x-axis.

explanation:

the instantaneous velocity = change in position/time taken

the slope of the graph should give instantaneous velocity.

  slope of a graph = change in value of y -axis / change in values of x -axis

  comparing both the equations

    change in value of y -axis = change in position

  change in values of x -axis = time taken

so position values should be on the y axis and time values should be on the x axis.

distance on the y-axis and time on the x-axis.

what is the actual question though?
