i need help with #2 and #3. it’s more about how i’m supposed to word it then just not knowing the answer

real, smaller and upside-down.   so the answer should be b.

  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.

54 degrees incident angle = reflected angle

angle is from normal turned to line of ray

a. vertically

explanation:

i tried it and took the test

if im wrong then we have different tests
