g A certain superconducting magnet in the form of a solenoid of length 0.440 m can generate a magnetic field of 9.10 T in its core when its coils carry a current of 80 A. Find the number of turns in the solenoid.

explanation:

v=uf/(u-f)

= 5.-10/(5+10) convex lens has negative focal length

i guess it’s a and b

  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.
