A child on a sled (m = 47.0 kg) slides down a long hill starting from a rest position at a point 10.0 m higher in elevation than his finishing point. a) What is the total mechanical energy present? b) Assuming that there's no friction and no external pushes, determine the child's speed at the bottom of the hill. c) The child's speed at the bottom of the hill is actually 5.0 m/s. Explain whether or not this defies the law of conservation of energy.

Q1. If the frequency of the HbS allele is 0.6 in a population, what is the frequency of the HbA allele (assuming this is a two-allele system)? Submit Q2. In the case study in this lab, which genotype is represented by "2pq" in the Hardy-Weinberg equation? Homozygous HbA Homozygous HbS Heterozygous HbA/HbS No specific genotype Submit Q3. In a population, if the proportion of individuals who have sickle-cell disease is 0.10, and the population is assumed to be at Hardy-Weinberg equilibrium, what is the expected frequency of the HbS allele? (Hint: What is the genotype of people with sickle-cell disease, and how is that genotype represented in the Hardy-Weinberg equation?) 0.32 Submit 0.18 0.90 0.01 Q4. In a population where the proportion of individuals who are susceptible to malaria (genotype HbA/HbA) is 0.70, and the population is assumed to be at Hardy-Weinberg equilibrium, what proportion of the population should be heterozygous HbA/HbS?

Write a program that will allow the user to enter which dish they wish to order. Then ask the user to enter any ingredients they want to add. Then ask the user to enter any ingredients they wish to remove. When the user is finished entering the data, print out the kitchen receipt formatted as follows: Dish Name + Thing one added + Thing two added - Thing one removed - Thing two removed - Thing three removed The user can add or remove up to 30 items. The user is not required to add or remove anything. You may also assume that the ingredients are one word (and thus do not contain spaces). You must implement the function int getItems(string arr[], size_t len). This function should NOT print anything to the console. This function stores the user's input until the user enters "quit". Since arrays are passed by reference, the array will be modified by the function and will remain modified when the function returns. It should return the number of items the user entered. Most of your code should go in void generateReceipt. This is essentially a main function and will contain the majority of the program logic. Example Output Here is an example of what your program's output should look like. It is vitally important that your program takes input in the same order as shown here. User input is in bold. ----------------------------------------------------------------------- This program generates a kitchen receipt specifying additions and removals for a dish. ----------------------------------------------------------------------- What is the main dish?

BankAccount.java is complete and will not need to be modified. 2. Create a new class called CheckingAccount that extends BankAccount. 3. It should contain a static constant FEE that represents the cost of clearing one check. Set it equal to 15 cents. 4. Write a constructor that takes a name and an initial amount as parameters. It should call the constructor for the superclass. It should initialize accountNumber to be the current value in accountNumber concatenated with...
