1-4: 1 SEE ANSWER

Force and stretch are proportional to one another such that if you double the force, the amount of stretch will double. If you triple the force, the amount of stretch will triple. If you half the force, the amount of stretch will halve. So the answers here are:

a. 32 N (twice the stretch requires twice the force)

b. 48 N (three times the stretch requires three times the force)

c. 8 N (one-half the stretch requires one-half the force)
