You learned that "The CPU interacts with memory in a process that is known as the fetch-decode-execute cycle. An instruction gets fetched (brought up) from memory, decoded (analyzed) in the control unit, and then executed (put into action) by the ALU." Can you think of a comparison to something that happens in real life that would make this process easier to understand and remember?

answer: a, c

divide any of the y values by x values and you will always get 3 is the most simple way i can put it for you.

only #2 represents an object at rest on a table.

in #1, there is no normal force due to the table; the object is accelerating downward.

in #3, the vertical forces are not balanced; the object is accelerating downward.

in #4, neither the vertical nor the horizontal forces are balanced. the object is accelerating upwards and to the right.
