I think it's better to post your question here :
And a little hint for you : the answer is no. Now your job is to find out the reason
that means if you apply N of force, the spring stretches m
cut the spring in half ... attach them with a light non-stretchable string.
apply a force of 8N. Each piece stretches m
the force in each spring "piece" is 8N
for two springs in series, the effective force constant of a single spring equivalent to the two is
