Answer 1
INCORRECT
As the elongation increases so does the force, when it doesn't the force doesn't. return to top
Answer 2
CORRECT
As the force increases so does the ability to strech it out, so the elongation increases at a constant (direct) rate. return to top
Answer 3
INCORRECT
They both increase, but they increase at the same rate. It is a direct relationship not an exponential one. return to top
Answer 4
INCORRECT
They both increase, but they increase at the same rate. return to top
