What common form of energy (not including kinetic or potential) is not included in the “energy symbols” key that would normally be present in these examples?

explanation:

as the height from which the ruler was dropped increased, the speed of the ruler at ryan's hand increased.

the answer is a. at the equator

which three statements are true about all alloys?

  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.
