Consider the following code: x = 9 y = -2 z = 2 print (x + y * z) What is output? 9 13 14 5

5

Explanation:

x = 9

y -2

x = 2

expression = (x + y * z)

Apply BODMAS rule.

= 9 + (-2 * 2)

= 9 + (-4)

= 9 - 4

= 5

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.
