B) Determine the apple's kinetic energy, K, the gravitational potential energy of the system, U, and the total mechanical energy of the system, E, when the apple's height above the ground is 3.0 m.

C) Determine the apple's kinetic energy, K, the gravitational potential energy of the system, U, and the total mechanical energy of the system, E, when the apple's height above the ground is 2.0 m.

1) Bob has just finished climbing a sheer cliff above a level beach and wants to figure out how high he climbed. All he has to use is a baseball, a stopwatch, and a friend on the ground below with a long measuring tape. Bob is a pitcher and knows that the fastest he can throw the ball is about ?0=33.7 m/s.Bob starts the stopwatch as he throws the ball, with no way to measure the ball's initial trajectory, and watches carefully. The ball rises and then falls, and after ?1=0.910 s. the ball is once again level with Bob. Bob cannot see well enough to time when the ball hits the ground. Bob's friend then measures that the ball hit the ground ?=125 m. from the base of the cliff.

How high above the beach was the ball when it was thrown?

2) A planet of mass ?=4.05×10^24 kg is orbiting in a circular path a star of mass ?=1.75×10^29 kg. The radius of the orbit is ?=4.35×10^7 km.

What is the orbital period (in Earth days) of the planet ?planet?

Tplanet = days

1. List ALL the different type of network connections involved in the operations for each of the scenarios below. Provide an illustration for each of the scenarios.

Scenarios a. You have just bought a new mobile phone from an online shop. You have decided to take a few snapshots of your best friend and send them to the email account of a mutual friend across the country. b. You are driving around in an unfamiliar city and have just gotten lost. By using your mobile phone’s GPS system, you submit a request for driving directions from a nearby intersection to your destination.

2. Broadcast networks refer to networks such as LANs connected by a technology such as Ethernet. Broadcast networks, by nature, are multiaccess where all routers in a broadcast network can receive a single transmitted packet. Discuss the requirements or deficiencies of a network layer (OSI layer 3 and TCP/IP layer 2) in a broadcast network.

Three forces act on an object. the first force is 37.5 lbs at 130.0 degrees, the second force is 28.0 lbs at 30.0 degrees east of south, and the third force is 11.0 lbs due south. What is the net force (magnitude and direction) exerted on this body?

Variable trials refers to a list where each list item is another list of 3 integers between 0 and 9. Imagine each list of 3 integers is a combination of numbers of a lock. Further suppose the variable code refers to a list of three integers that is the correct combination of the lock.

Write a program which, assuming trials and code are already defined, prints out a character for each digit of each trial. Print Y if the digit in the trail matches the digit at the same position in the code. Print # if the digit in the trial does not match the digit at the same position in the code but appears elsewhere in the code. Print N if the digit of the trial does not match the digit in the code and the digit in the trial appears nowhere in the code. Print a newline after the characters after three numbers (for each trial).

Example, if trails = [[2,3,4], [5,5,5], [5,2,3]], and code = [2,3,5], the program output should be:

Y Y N

# # Y

# # #

Hint: the in and not in operators can be used to test whether an item appears in a list.

Can a Single Online Respondent Pool Offer a Truly Representative Sample?

Online research programs can often benefit by building samples from multiple respondent pools. Achieving a truly representative sample is a difficult process for many reasons. When drawing from a single source, even if researchers were to use various verification methods, demographic quotas, and other strategies to create a presumably representative sample, the selection methods them- selves create qualitative differences—or allow them to develop over time. The same is true of the parameters under which the online community or respondent pool was formed (subject matter mix, activities, interaction opportunities, etc.). Each online community content site is unique, and members and visitors choose to participate because of the individual experience their preferred site provides. As such, the differences between each site start to solidify as site members share more and more similar experiences and differences within the site’s community decrease. (Think, birds of a feather flock together.)

As such, researchers cannot safely assume that any given online respondent pool offers an accurate probability sample of the adult U.S. or Internet population. Consequently, both intrinsic (personality traits, values, locus of control, etc.) and extrinsic (panel tenure, survey participation rates, etc.) differences will contribute variations to response‐measure distribution across respondent pools. To control distribution of intrinsic characteristics in the sample while randomizing extrinsic characteristics as much as possible, researchers might need to use random selection from multiple respondent pools.

The GfK Research Center for Excellence in New York performed a study to see how the distribution of intrinsic and extrinsic individual differences varied between respondent pools. Respondents were drawn from five different online resource pools, each using a different method to obtain survey respondents. A latent class regression method separated the respondents into five underlying consumer classes according to their Internet‐usage driver profiles.

Researchers then tested which of the intrinsic characteristics tended to appear within the different classes. No variable appeared in more than three classes. Furthermore, the concentration of each class varied considerably across the five respondent pools from which samples were drawn.

Within the classes themselves, variations appeared in their demographic distributions. One of the five experienced a significant skew based on gender, and two other classes exhibited variable age concentrations, with one skewed toward younger respondents and the other toward older ones.

Overall, GfK’s study revealed numerous variations across different respondent resource pools. As their research continues, current findings suggest that researchers must be aware of these trends, especially in choosing their member acquisition and retention strategies and in determining which and how many respondent pools to draw from.

1. If one respondent pool is not sufficient, how many do you think you would have to draw from to get a truly representative sample? Why do you think that?
2. When creating a sample, how would you propose accounting for the types of extrinsic characteristics mentioned?

Equivalent Units of Production

The Converting Department of Hopkinsville Company had 640 units in work in process at the beginning of the period, which were 70% complete. During the period, 13,600 units were completed and transferred to the Packing Department. There were 720 units in process at the end of the period, which were 60% complete. Direct materials are placed into the process at the beginning of production.

Determine the number of equivalent units of production with respect to direct materials and conversion costs. If an amount is zero, enter in "0".
