Explanation:
the water temperature increase or decrease
<span>So the question is to unscramble all of the words that are types of heat-creating energy and they are: LACECHMI, CEIECTLR, IRITONFC, AREOGLHMET, LCRNEAU, ROASL. So LACHECHMI is CHEMICAL, CEIECTLR is ELECTRIC, AREOGLHMET is GEOTHERMAL, LCRNEAU is NUCLEAR and ROASL is SOLAR. </span>
When the spring is extended by 44.5 cm - 34.0 cm = 10.5 cm = 0.105 m, it exerts a restoring force with magnitude R such that the net force on the mass is
∑ F = R - mg = 0
where mg = weight of the mass = (7.00 kg) g = 68.6 N.
It follows that R = 68.6 N, and by Hooke's law, the spring constant is k such that
k (0.105 m) = 68.6 N ⇒ k = (68.6 N) / (0.105 m) ≈ 653 N/m
