A light spring obeys Hooke's law. The spring's unstretched length is 32.5 cm. One end of the spring is attached to the top of a doorframe and a weight with mass 8.25 kg is hung from the other end. The final length of the spring is 45.5 cm. (a) Find its spring constant (in N/m). N/m (b) The weight and the spring are taken down. Two people pull in opposite directions on the ends of the spring, each with a force of 150 N. Find the length (in m) of the spring in this situation. m (c) What If? What would be the length (in m) of the spring if it were now attached to the vertical portion of the doorframe and stretched horizontally by a single person exerting a force of 150 N? m

answer;

d. are made mostly of liquid

explanation;

-the general   composition and structure planets includes; they have a thick gas and liquid layer covering a small,solid core. mostly the gases are hydrogen and helium atmosphere and layers of liquid hydrogen. for instance neptune and uranus are examples of the outer planets, they have a core covered by ice and ammonia.

-neptune's atmosphere is hydrogen and helium with a bit of methane so there is no oxygen to breath and the interior is made up of frozen water and ammonia with a rock and iron core. thus, there is no liquid water or solid surface to survive.
