6. A block and tackle with 4 pulley wheels and 4 supporting ropes is used to lift a 250-pound weight. To lift the weight 3 feet, the rope will have to be
pulled
feet.

a lot of it means it can be "burned" for energy and sold at one price. if it is scarce, the price will go up

the motion of a pendulum is a classic example of mechanical energy conservation. a pendulum consists of a mass (known as a bob ) attached by a string to a pivot point. as the pendulum moves it sweeps out a circular arc, moving back and forth in a periodic fashion.

  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.
