5. a. Suppose someone, whose temperature is originally 37 °C, is murdered in a room that has constant temperature 25 °C. The temperature is measured as 28°C when the body is found and at 27 °C 1 h later. How long ago was the murder committed from discovery of the body? See Exercise 4 for New- ton's Law of Heating and Cooling. b. Suppose we are performing a simulation using a step size of 0.004 h. Using the decay rate from Part a, determine the temperature at the end of the first three time steps after discovery of the body.

Problem 7: On a hot day, the freezers in a particular ice cream shop maintain an average temperature of Tc = -11° C while the temperature of the surroundings is Th = 27° C.Randomized VariablesTc = -11° CTh = 27° C Part (a) Calculate the maximum coefficient of performance COP for the freezers. Part (b) If the work input to the freezer is W = 2.65 kJ and the freezer actually removes Qc = 7.8 × 103 J from the ice cream each second, what is the real coefficient of performance? Part (c) An employee puts m = 1.65 kg of melted ice cream at T0 = 3.5° C into the freezer. Assuming that the ice cream freezes at T1 = -1.0° C, how long in seconds will it take for the ice cream to reach its freezing temperature? Take the specific heat capacity of the melted ice cream as c = 4,000.0 J/(kg⋅K). Part (d) Assuming a latent heat of fusion of Lf = 280 kJ/kg, how long, Δt2, in seconds does it take to freeze the ice cream?
Referring to Figure 10.11, suppose you have some lizards thatare at 16°C and have been living at that temperature for 5 weeks.What is their resting metabolic rate? If the lizards are suddenlyshifted to a room at 33°C, trace on the graph how their metabolicrate will change from the moment they are placed in the newroom until 5 weeks have passed. According to the graph, willthey exhibit compensation?
The parts department of a large automobile dealership has a counter used exclusively for mechanics’ requests for parts. The time between requests can be modeled by a negative exponential distribution that has a mean of five minutes. A clerk can handle requests at a rate of 15 per hour, andthis can be modeled by a Poisson distribution that has a mean of 15. Suppose there are two clerksat the counter.a. On average, how many mechanics would be at the counter, including those being served?
From an open water surface with air temperature 22°C, relative humidity is 40% and wind speed is 3 m/s, all measured at height 2 m above the water surface. Assume a roughness height of 0.03 cm.

Math, 11.11.2020 07:15, kateclaire The force-deflection relation of a steel helical spring used in an engine is found experimentally as f(x) = 200x+50x2 +10x3 where the force (f) and deflection (x) are measured in pounds and inches, respectively. If the spring undergoes a steady deflection of 0.5 in. during the operation of the engine, determine the equivalent linear spring constant of the spring at its steady deflection.
Thermodynamics Answer the following problem with complete solutions. Write legibly A balloon is filled with pure oxygen at 10 ℃. The balloon is released from the bottom of a water-filled testing pool and floats 30 m to the water surface (where the atmospheric pressure is standard). The volume of the balloon is 3,000 cm^3. The temperature is 25 ℃ at the surface of the water, and the water temperature at the bottom of the pool is 10 ℃. What is the volume of the balloon at the surface after it has come into thermal equilibrium with the surroundings
Suppose four 30-g ice cubes are added to a glass containing 200 cm3 of orange juice at 20,0°C.You may assume that the orange juice has a density and specific heat capacity the same as water namely: Density = 1,0 g∙cm–3 and specific heat = 4,184 J/gK The heat of fusion (of water) is 333 J/g.Your task is twofold. You must determine:a) Whether or not all the ice will melt; andb) If your finding is that some ice will be left in the juice, you must calculate what mass of ice will be present the moment when thermal equilibrium is reached.
1) Second order stress tensor represents the state of stress at a point in a mechanical part (SEE IMAGES). The eigenvalues of σ are the principal stresses at the corresponding point, which are important for determining when the mechanical part will yield. Use the characteristic equation to determine the principal stresses of σ. Please show your steps. 2) Given that an eigenvector, v, corresponding to a particular eigenvalue, λ˜, of σ must satisfy (σ − λ˜I)v = 0, find the eigenvectors associated with the eigenvalues from (b). You may use software to verify your answer but please show your steps. Draw the eigenvector and eigenvalue.
