Need help with a python expression

Explanation:

n Python, an expression involving values of a certain type produces a value of that same type. For example, 17 and 10 are integers—in Python, we say they are of type int. When we divide one by the other, the result is also an int. Notice that Python doesn’t round integer expressions.

Explanation:

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.
