A 15 kg block is at the top of a 15 m ramp that has an angle of 30°.
a. What is the force of gravity going
down the ramp?
b. What is the normal force?
c. What is the acceleration of the
block down the ramp?
d. What is the final speed of the block
at the bottom of the ramp?

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

frequency or wavelenth of em radiation in a vacuum

  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.
