The following data were collected for Part I of the lab procedure. Complete the table. The force is due to the gravitational force. All distances are measured from the bottom of the hanger to the top of the stool. You should ignore the initial weight of the hanger. * Does the Period of a Pendulum lead to the Δx(m) and Force (N)? How do I get (m) and force (N), thanks.

If a refrigerator is a heat pump that follows the first law of thermodynamics, how much heat was removed from food inside of the refrigerator if it released 380j of energy to the room?

Four friends, a, b, c, and d are standing varying distances away from a speaker which is producing sound waves.

Asteel tube (k=50 w/mk) of inner and outer diameter di = 20mm and do=26mm, respectively, is used to transfer heat from hot gases flowing over the tube (h-hot = 200w/m2k) to cold water flowing through the tube (h-cold = 8000 w/m2k). what is the cold-side overall heat transfer coefficient uc? to enhance heat transfer 16 straight fins of rectangular profile are installed longitudinally along the outer surface of the tube. the fins are equally spaced around the circumference of the tube, each having a thickness of 2mm and a length of 15mm. what is the corresponding overall heat transfer coefficient uc? *solve for uc in both cases*
