Select the equations used when solving the above problem:  (The original problem: For a given thermopane window of area A with R value, determine the amount of heat loss through this window in one hour if the temperature difference between inside and outside of the window surfaces is T.)

The same amount of three substances –  0oC ice-cold water 0oC ice cubes -4oC ice cubes are separately added to 300 g of warm water at 25oC. Rank the mixtures by their final equilibrium temperatures, from the hottest (#1) to the coldest (#3).

For a physics experiment, a solid cube is suspended from a spring scale. The gravitational force exerted on the cube is 0.714 N as measured when the object is suspended from a spring scale. When the suspended cube is submerged in water (ρ = 1000 kg/m3), the scale reads 0.450 N.   Determine the buoyant force (in units of N) acting on the cube based upon the force measurements.

 {m}-g of ice cubes at 0°C is added to 300-g of water at 25°C.  What is the final equilibrium temperature of the mixture in oC?  Assume that no energy is lost in this process and ignore the amount of heat absorbed by the container.  Enter your unit as “C”.

Exam requirements help us ensure exam integrity and help reduce false flags so that you don’t inadvertently jeopardize your opportunity to do the course bonus. The questions below remind you of the requirements, which you’ll certify by answering that you have followed or will be following: A. My ID image clearly shows the front of my UW ID (or instructor approved alternate photo ID). B. My scan clearly shows my 360 room/space scan and also my entire work surface (i.e., desk, table top). C. I will keep my face and upper body clearly and continuously in view of my camera. I am not wearing a hat or face covering, the lighting clearly shows my face, and I will not move out of the camera view.  D. I’m in a quiet room/space. There will be no music, no talking including me talking aloud, or other sounds.  E. I’m in a private room/space. There will be no interruptions, no people in the background or passing through my video. F. My work surface is uncluttered. It only has my scratch paper and a couple pencils and/or pens. G. I will not use any other devices or sources. I’ve turned off, put out of reach and out of sight any phones, smartwatches, calculators, headphones/earbuds, etc. and have covered any additional monitors so that they can’t be used. I understand this is a closed-book exam. H. I will use the online form to report any issue that might compromise the integrity of my exam, such as disconnections and accidental interruptions. Finish this question by showing to the camera both sides of each sheet of your loose scratch paper (2 sheets maximum). Now you may continue with the exam.

Polk County trash-collection fees are to rise at the end of this year.  The current rate for trash collection is $207 annually.  The rate is to increase to $337 by the end of the year due to new contract negotiations. What is the relative change in the trash-collection fee? Actual Change:  New Value – Original Value Relative Change:
