Aperson is pushing a box across a table. the measured forces on the box are 10n, 14n, -7n, -10n.

which force is represented by -7n?

Friction

Explanation:

Assuming that the box is moving forwards, -7N would have to be friction, and 14N is the push force applied to the box.

-7N cannot be equal to gravity because the normal force and force of gravity must cancel out, so gravity would be -10N and normal force is 10N.

it should be -8.6 cm hope this out

  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.
