Amy's 8-month-old daughter is always grabbing things and putting them in her mouth. Amy has to make sure to watch her at all times, otherwise she might eat dust bunnies, threads from the carpet, sand, and coins. Does Amy's daughter have pica? A. Yes. B. No, because Amy's daughter's behavior is not developmentally inappropriate. C. No, because the exact items she is eating do not fall under the categories specified in the diagnostic definition of pica. D. No, because a person cannot be diagnosed with pica until he or she is 2 years old.

You are asked to evaluate the performance of heat engines that produced work output based on the heat exchange with the heat reservoirs. As shown in Figure Q2, two reversible heat engines are arranged in such a way that they each produced the same net work, $W_{cycle}$. The first cycle receives energy $Q_H$ by from a hot reservoir operating at $T_H$ and rejects energy Q to a reservoir at an intermediate temperature, T. It was also shown that the second cycle receives energy Q from the reservoir at temperature T and rejects energy $Q_C$ by heat transfer to a reservoir at $T_C$. The direction of the energy transfers are the same as in the directions of the arrows. Determine: i. The temperature T; ii. The thermal efficiency of each of the two power cycles iii. As a way to improve $W_{cycle}$, you proposed to install a single reversible power cycle operating between $T_H$ and $T_C$. Do you think that the power developed by having this single power cycle is higher? If yes, why? If no, why? Show your calculations Refer Table Q2 for your $T_H$ and $T_C$ values.

Write a program in Python that generates a random number between 1-100. The user is then asked to guess the number. If the guessed number is within 10 numbers higher or lower, the program will display "Close". Otherwise, it will display "Keep trying". When the user guesses the number, the program will say "Correct" and display the number of attempts. Lastly, the program will give the user the choice to either start again or quit.

A linear city representing the dimension of "mouth feel" in breakfast cereals has 101+ consumers spread uniformly along it. Note that the third last digit of your student ID number is the total number of consumers. For example, if your student ID number is SB709394, then the total number of consumers is 104. Suppose that in the linear city, there are only two shops selling cereals. Each consumer will buy one package of cereal a week and incur disutility 0.5 from each unit distance by which a brand deviates from their favorite mouth feel. The utility of a consumer who eats breakfast cereals is given by: U = A - price of cereals - total cost of transportation, where A is a constant. (a) What are the equations for both firms' demand curves? (b) What are the symmetric equilibrium outcomes under free entry if the cereal makers' cost functions are given by Ci = B, where B is a constant?
