HELP!! Which type of
electromagnetic radiation is used in security baggage
scanners, and why?
A. Radio, because its low energy makes it safe for the machine
operators
B. Gamma rays, because they are high-frequency waves, which
causes them to easily bend around the objects in the baggage
C. X-rays, because they either pass through or are absorbed by the
objects in the baggage, creating an image of the objects
D. Infrared, because the waves are reflected by the objects in the
baggage, creating an image of the objects

a electromagnetic waves

  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.
