A 5000 Hz sound wave is emitted by a stationary source. This sound wave reflects from an object moving at 3.50 m/s toward the source. What is the frequency of the wave reflected by the moving object as detected by a detector at rest near the source?

Including the original call to the mystery method, how many times is the method called?

A sound wave travels twice as far in neon (Ne) as it does in krypton (Kr) in the same time interval. Both neon and krypton can be treated as ideal monoatomic gases. The atomic mass of neon is 20.2 u and the atomic mass of krypton is 83.3 u. The temperature of krypton is 293 K. What is the temperature of neon?   (The masses can remain with the mass unit that is given in the problem – you do not need to convert.)

A specific numeric value is often called a(n) ____.

Identify the following functional group(s).

In one or two sentences explain why code such as that described in Question 2 is necessary.

What concept refers to a person’s fairly consistent pattern of acting, thinking, and feeling?

Write the output that is printed when the given method below is passed the following map as its parameter: {pumpkin=peach, corn=apple, apple=apple, coffee=java, pie=fruit, peach=peach} Assume that each parameter map stores its key/value pairs in exactly the order shown, and that is the order in which a for-each loop would examine them. Recall that maps print in a {key1=value1, key2=value2, …, keyN=valueN} format. Your answer should display the right values in the right order.

Give the IUPAC name for the following.  Include stereochemistry if necessary.
