1. A rock is thrown downward into a well that is 8.70 m deep.
If the splash is heard 1.10 seconds later, what was the initial speed of the rock? Take the speed of sound in the air to be 343 m/s.
2. A bird-watcher is hoping to add the white-throated sparrow to her "life list" of species. Person, only 1.00 m from the bird, hears the sound with an intensity of 2.68×10?5 W/m2 .
How far could she be from the bird and still be able to hear it? Assume no reflections or absorption of the sparrow's sound.
3. At Zion National Park a loud shout produces an echo 2.00 s later from a colorful sandstone cliff.
How far away is the cliff? Take the speed of sound in the air to be 343 m/s .

C program and pseudocode for this problem.
A parking garage charges a $2.00 minimum fee to park for up to three hours and additional $0.50 per hour over three hours. The maximum charge for any given 24-hour period is $10.00. Assume that no car parks for longer than 24 hours at a time. Write a program that will calculate and print the parking charges for each of three customers who parked their cars in this garage yesterday. You should enter the hours parked for each customer. Your program should print the results in a tabular format, and should calculate and print the total of yesterday's receipts. The program should use the function calculateCharges to determine the charge for each customer. Your output should display the car #, the hours entered and the total charge.

Write an anecdotal lead with a person focus from the following information; include a nut graph. Your focus is about the frustrations that students experience trying to park on campus because the parking department has sold too many permits.
Background: Nancy Pauw is a graduate student. One morning, she circled the parking lot east of the computer center three times before she found a parking space. Last year, there were 7,565 student parking permits sold for 3,930 spaces. “I have to get here an hour early so I can get to class on time,” Pauw says. She is one of many students (on your campus) who experience the daily frustration of not finding a parking spot even though they have purchases $30 and $50 permits.

In our textbook, we learn that Disney has acquired several companies throughout the years including Marvel for $4 billion in 2009. One main advantage that this acquisition allowed Disney to do is increase the differentiation in their product offerings. They were able to add and entire line of superheroes to the Disney character family, which also allowed to add Marvel character theme park rides, toys, and other merchandise. Not only did this benefit Disney, but the acquisition also added value to Marvel. "Because of economies of scope and economies of scale, Marvel is becoming more valuable inside Disney than as a standalone enterprise" (Rothaermel).
Our question for you is, besides being able to increase their product offerings, what other benefits do you think this acquisition brought to Disney as a company?
