A paper clip that has a mass of 1.5 grams is thrown into the air and initially has a kinetic energy
of 0.013 J.
Calculate the velocity of the paper clip when it is thrown (rounding your answer to the nearest
tenth)

Explanation:

Given data:

Mass of the paper clip,

Kinetic energy,

Let the velocity of the paper clip when it is thrown be v.

Thus,

 (rounding to nearest tenth)

  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.

the answer is the first electromagnet (a). this is because it has more coils around the ferromagnetic material. increasing the number of coils increases the surface area in which the metal interacts with the current in the coil. this enables more atoms in the metal to become aligned hence becoming more magnetized.
