A student pushes a 40-N block across the floor for a distance of 10 m. How much work was done to move the block? 4 J 40 J 400 J 4,000 J.

Explanation:

Work is a force that causes the displacement of an object. It is the product of force and displacement.

The force is 40 Newtons and the displacement is 10 meters.

Substitute the values into the formula.

Multiply.

Convert the units. 1 Newton meter is equal to 1 Joule, so our answer is equal to 400 Joules.

400 Joules of work was done to move the block.

the answer is kevlar

  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.
