If a runner exerts 350 J of work to do 125 W of power, then how long did it take the runner to do the work

layers of the earth affect the waves and these effects are seen on instruiments such as seimometers

no. dot product   =0 when vecs at right angles

  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.
