wood block 1 which has a mass 1.0kg is at rest on a wood ramp. The angle of the ramp is 20 degrees above horizontal. What is the smallest mass of block 2 that will start block1 sliding uphill.

when heated, the valance electrons increased their speed and transferred the heat from electron to electron.   i just took the test.

  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.
