Newton's Law of cooling states that the rate at which heat is lost by a heated body is proportional to the difference in temperature between the body and the surrounding medium. Match the following statements/phrases with the corresponding item in the drop down box. Choices in the box 1. In accordance with the stated law obove, we have the equation? 2. If a thermometer is taken outdoors where the temperoture is 5 deg C, from a room in which the temperature is 20 deg C and the reading drops 10 deg C in one minute, the working equation is? 3. In the obove problem, separoting the variables and integrating will result to? 4. In the obove problem, how long, in minutes, after its removal from the room will the reading be 6 deg C? 5. In the obove problem, ofter 30 seconds, whot will be the thermometer reading? 5.2 dT(body temp)/dt = k(Temp of medium - 5) dr(body temp)/dt = k(Temp of body - Temp of medium) Temp of body = Cenkt +5 2.5 13.7 dr(body temp)/dt = k(Temp of medium - Temp of body)…

Part II https://www.youtube.com/watch?v=jqDMw-9JZsA Observation: Answer the following: What causes the object to float in sea water and sink in fresh water? Questions: Why do fluids exert an upward buoyant force on submerged objects? A huge spherical helium filled balloon painted to look like a cow is prevented from floating upward by a rope tying it to the ground. The balloon plastic structure plus all the helium gas inside of the balloon has a total mass of 9.20 kg. The diameter of the balloon is 3.50 m. The density of the air is 1.23 kg/ m3. What is the tension in the rope?

from this video: https://youtu.be/UvMmfacVA24 COntext: From the first setup where there is no newspaper present, the ruler fell down easily as I do a quick karate chop. In the second setup where there a sheet of newspaper over the ruler that is on the table, the ruler broke as I karate chop the ruler because of the atmospheric pressure present below and above the paper. When the paper was suddenly forced up by the ruler. A low pressure forms under the paper like a vacuum sucking the paper down and resulted in the ruler cutting in half. Explain the difference in the results of the setups using concepts about fluids. Use schematic diagrams/FBD if needed.

You are a biomedical engineer working for a small orthopaedic firm that fabricates rectangular shaped fracture fixation plates from titanium alloy (model = "Ti Fix-It") materials. A recent clinical report documents some problems with the plates implanted into fractured limbs. Specifically, some plates have become permanently bent while patients are in rehab and doing partial weight bearing activities. Your boss asks you to review the technical report that was generated by the previous test engineer (whose job you now have!) and used to verify the design. The brief report states the following... "Ti Fix-It plates were manufactured from Ti-6Al-4V (grade 5) and machined into solid 150 mm long beams with a 4 mm thick and 15 mm wide cross section. Each Ti Fix-It plate was loaded in equilibrium in a 4-point bending test (set-up configuration is provided in drawing below), with an applied load of 1000N. The maximum stress in this set-up was less than the yield stress for the Ti-6Al-4V…

Task 3 You are an engineer working in a chemical lab, you are conducting an experiment that involve a phase change, your co-worker asked you to explain the relationships between system constants for a perfect gas, answer the following questions to help your colleague to understand the process: Q1. Discuss the difference between gas constant (R) and universal gas constant (Ru)? Explain how the two constants are related? Q2. Propane and methane are commonly used for heating in winter, and the leakage of these fuels, even for short periods, poses a fire danger for residential application. Which gas leakage do you think poses a greater risk for fire? State the reason. Q3. What is the ideal gas equation? Explain the relationship between pressure, temperature and volume in the ideal gas equation? In addition, discuss under what conditions is the ideal-gas assumption suitable for real gases?

⦁ “God himself could not sink this ship” This is an advertisement for the Titanic, produced in the early 1900s. However, after colliding with an iceberg at dawn on April 15, 1912, two rivers were formed, and out of the 2,200 people on board, 1,500 people, including the captain, sank with the ship. According to a later investigation, the “temperature change theory” (DBTT theory) was the most promising cause of the sinking. Give a brief guess of the cause of the ship's sinking in relation to temperature.

Inspired by a science fiction story, physicist Freeman Dyson described such a structure for the first time in a scientific paper in 1959. His basic idea consisted of an artificial spherical structure of matter built around a star at a distance comparable to a planetary orbit, with the purpose of capturing the energy radiated by the star and reusing it for industrial purposes Assume the mass of the sun to be 2.00x1030 kg Part A Consider a solid, rigid spherical shell with a thickness of 100 m and a density of 3900 kg/m.
