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?

Citrus trees are very susceptible to cold weather, and extended exposure to subfreezing temperatures can destroy the crop. In order to protect the trees from occasional cold fronts with subfreezing temperatures, tree growers in Florida usu ally install water sprinklers on the trees. When the temperature drops below a certain level, the sprinklers spray water on the trees and their fruits to protect them against the damage the subfreezing temperatures can cause. Explain the basic mecha nism behind this protection measure and write an essay on how the system works in practice.

Geochemical Box Models - please use same terminology found in question Consider an element X exchanging between two geochemical reservoirs A and B. Let MA and MB be the masses of X in reservoirs A and B, respectively; let tA and tB be the residence times of X in reservoirs A and B, respectively. Further let M = MA + MB be the total mass of X in the two reservoirs combined. Consider a situation where additional mass M' is injected into reservoir A at time t=0 increasing the total amount of element X in the system from M0 to M1, with no further injection at later times; further assume that tA >> tB, that the total mass in the altered system is M1 = M0 + M', and that M0 << M'. Give an expression for MB(t) as a function of M1, tA, tB, and t. What is the characteristic time for MB to approach steady state? What is the characteristic time for MA to approach steady state?

PROBLEM: VID-3 BOOK: ENGINEERING THERMOFLUIDS, M. MASSOUD (please can you answer my question even if it's rough computation)

The title of our study is "Design and Fabrication of an Agricultural Spraying Attachment for an Autonomous Rover" we need help in the machine design part of our study, specifically Pump selection, battery selection, and center of gravity computation I already sent you the image of the rover Rover weight capacity 35 kilo grams (payload) Rover measurements: Wheel distance - 14.5 inches and 8.5 inches Rover platform size (width & length) 14.4 inches x 10.4 inches Height- 15.8 inches. Water tank selection More or less 25 liters *For tank selection we need to justify the size with the center of gravity, proving that is the maximum dimension or liters of the tank because the center of gravity will be higher making the rover prone to toppling Pump selection *Our sprayer design has two nozzles which splits using a tee splitter, we need to find the size of the pump to obtain the same discharge rate of a normal sprayer. A normal sprayer has a 12V pump and a pressure from 0.2 to 0.45 mpa…

a) The number of kilocalories in food is determined by calorimetry techniques in which the food is burned and the amount of heat transfer is measured. How many kilocalories per gram are there in a 5.00-g peanut if the energy from burning it is transferred to 0.500 kg of water held in a 0.100-kg aluminum cup, causing a 54.9C temperature increase? (b) Compare your answer to labeling information found on a package of peanuts and comment on whether the values are consistent.

Given: Mass = M, Radius = R, Moment of Inertia = I, Distance =  H, Gravity = g, Initial timing = 0 Unknown =  How long will the [delta t] process take? (time) Please keep in mind that almost every variable is unknown! We are given no numbers and are instructed to generate a solution using the variables [ "R, M, g, I and H." ]  Target =  Find an equation that, if we could substitute numbers, would determine how long the process would take.  Newton's second law and torque seem to be relevant based on how the problem is written. * Also please show drawing based on what we are calculating

First read Section 2.14 of the Kaminski & Jensen text entitled, The “Pizza” Procedure for Problem Solving (silly name maybe, but it underscores the need to break large problems intomanageable parts). In describing the major parts of the procedure for solving engineeringproblems, an analogy is made to a stool with three legs. Name and describe in a few words the3 “legs” of the procedure for solving engineering problems:

In a linear spring finite element model, as per the finite element model’s sign convention, which one of the following statements is true?   Select one: a. If Fe1 is positive then the spring is under tension b. If Fe2 is negative then the spring is under tension c. If Fe2 is positive then the spring is under compression d. If Fe1 is positive then the spring is under compression Clear my choice

Matlab

Learning Goal: To use the principle of linear impulse and momentum to relate a force on an object to the resulting velocity of the object at different times. The equation of motion for a particle of mass m can be written as ∑F=ma=mdvdt By rearranging the terms and integrating, this equation becomes the principle of linear impulse and momentum: ∑∫t2t1Fdt=m∫v2v1dv=mv2−mv1 For problem-solving purposes, this principle is often rewritten as mv1+∑∫t2t1Fdt=mv2 The integral ∫Fdt is called the linear impulse, I, and the vector mv is called the particle's linear momentum.   A tennis racket hits a tennis ball with a force of F=at−bt2, where a = 1300 N/ms , b = 300 N/ms2 , and t is the time (in milliseconds). The ball is in contact with the racket for 2.90 ms . If the tennis ball has a mass of 59.7 g , what is the resulting velocity of the ball, v, after the ball is hit by the racket?

You are testing a long-dwelling catheter for its biological response using a rat model. After implantation for 4 months you explant the catheter material and surrounding tissue. Histology shows the catheter material surrounded by a thin layer of aligned collagen that is, in turn, surrounded by numerous polymorphonuclear cells. What has occurred? Describe the short term and long term events that led to this outcome. Note: the fact that this is a rat model rather than a human is not the issue - the model is fine.

a) Assuming the effluent from the pulp and paper plant has a daily discharge of 15 m3/s, calculate the daily loading values for TSS and BOD5. (Remember: Loading (kg/day) = Q (m3/s) x concentration (mg/L)) **don’t forget your unit conversions and show your work if you can Assume a BOD5 concentration of 10 mg/L, and a TSS of 20 mg/L.

Simulated Annealing How would Simulated Annealing perform if the temperature, T, is always equal or very close to 0, where we omit the termination test (except that we terminate the search when a goal node, either a local or global optimum, is met)?

You are the mechatronics engineer of a manufacturing plant. You decide to perform an analysis on a robot arm of the assembly line with the objective of optimizing its performance. After taking several readings of the speed of the arm’s end effector, you approximate its velocity to the function given below. v(t) = -t4 + 5t3 - 7t2 + 3t + 0.22                                       0 =< t =< 3 where the velocity is in ms-1   d) Knowing that the distance travelled by an object is the area under its velocity-time graph, determine the distance travelled by the end effector on the interval 0 =< t =< 1  by using the mid-ordinate rule. Simpson’s rule correct to 3 decimal places using four intervals. e) Calculate the same distance as in (d) above by using the appropriate definite integral. f) Compare the distances you calculated in (d) and (e) above and comment on the accuracy of the two methods you used in (d)
