To generate integers between and including - 10 to 10 you would use: randint(-10, 10)

random. random()*20 +
-10

random. randint(-10, 10)

random. random(-10, 10)

random.randint(-10, 10)

Explanation:

random.randint(a, b)

Return a random integer N such that a <= N <= b. Alias for randrange(a, b+1).

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.
