Explanation:

Question 7

When two forces act in the same direction, their magnitudes combine to give a larger net force. So we add the magnitudes of the two forces. Among the options, "add" is the correct operation.

When two forces act in opposite directions, the net force is the difference between the magnitudes of the two forces (we subtract the smaller magnitude from the larger one). So we use subtraction. Among the options, "subtract" is the correct operation.

Answer:

add
