I think the correct answer would be that Charles' law explains why <span>a balloon deflates when the air around it cools. Charles' law is a simplification of the ideal gas law. At constant pressure, volume and temperature have a direct relationship. Hope this helps.</span>
Provided the projectile is landing at the same elevation as it is launched from, it is 45 degrees
Answer:

Explanation:
For this exercise let's use hooke's law
F = - k x
where x is the displacement from the equilibrium position.
x =
if we have several springs in series, the total displacement is the sum of the displacement for each spring, F the external force applied to the springs
x_ {total} = ∑ x_i
we substitute
x_ {total} = ∑ -F / ki
F / k_ {eq} = -F
1 / k_ {eq} = ∑ 1 / k_i
if all the springs are the same
k_i = k
