Who is The Brain? Is he our father/mother/god?

its pretty much a bot i mean someone had to make the account but its only a bot that is being used.

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.
