Now, please respond to the following discussion “No Man is an Island”:

• Suggest at least one (1) scenario in which understanding the Five Stages of Group Development could help you to work more effectively in groups in the future. Provide a rationale for your response. Then, reflect on an experience that you had being a member of a team. Classify the good, bad, and tolerable characteristics of being a team member.
• I need 1-2 reference in APA format

I need help with two essay questions.

1.  How does imagery help evoke emotion in this poem?  Choose three images from the poem and
describe the emotions that the images evoke. 
Explain how the images are connected to the emotions.

To Marguerite: Continued

BY MATTHEW ARNOLD

Yes! in the sea of life enisled,

With echoing straits between us
thrown,

Dotting the shoreless watery wild,

We mortal millions live alone.

The islands feel the enclasping
flow,

And then their endless bounds they
know.

But when the moon their hollows
lights,

And they are swept by balms of
spring,

And in their glens, on starry
nights,

The nightingales divinely sing;

And lovely notes, from shore to
shore,

Across the sounds and channels
pour—

Oh! then a longing like despair

Is to their farthest caverns sent;

For surely once, they feel, we were

Parts of a single continent!

Now round us spreads the watery
plain—

Oh might our marges meet again!

Who ordered, that their longing’s
fire

Should be, as soon as kindled,
cooled?

Who renders vain their deep
desire?—

A God, a God their severance ruled!

And bade betwixt their shores to be

The unplumbed, salt, estranging
sea.

2.  How does “London” reflect the issues and characteristics of the
Romantic period?  Describe three ways in
which the poem discusses or comments on the problems or issues.  Your response should be 1-2 paragraphs long.

London

BY WILLIAM BLAKE

I wander thro’ each charter’d
street,

Near where the charter’d Thames
does flow. 

And mark in every face I meet

Marks of weakness, marks of woe.

In every cry of every Man,

In every Infants cry of fear,

In every voice: in every ban,

The mind-forg’d manacles I
hear 

How the Chimney-sweepers cry

Every blackning Church
appalls, 

And the hapless Soldiers sigh

Runs in blood down Palace
walls 

But most thro’ midnight streets I
hear

How the youthful Harlots curse

Blasts the new-born Infants
tear 

And blights with plagues the Marriage hea

Lab
Assignment 7:  Circular Motion

Instructor’s Overview

Circular motion is an integral part of our
everyday lives.  We experience circular
motion when we leave highways on cloverleaf exits and on amusement park
rides.  Countless systems and devices
leverage circular motion.  We will
discuss real-world applications in this module’s discussion.  In this lab, you will directly experiment
with uniform circular motion and quantify the behavior of a simple system.  To execute the lab, you’ll synthesize your
knowledge and experience with free-body diagrams and Newton’s second law.

In this lab, you will create a simple
system of two different masses connected by a piece of fishing line.  Here’s the twist: The fishing line is
threaded through a tube.  You will rotate
the tube and achieve an equilibrium situation where the lower mass is
vertically stationary.  You will then use
your knowledge of circular motion to analyze the situation.

This activity is based on Lab 8 of the
eScience Lab kit.

Take detailed
notes as you perform the experiment and fill out the sections below.  This document serves as your lab report.  Please include detailed descriptions of your
experimental methods and observations.

Experiment Tips: 

· 
Make
sure you use fishing line instead of string for the experiment.  Can you guess why?

· 
Be
careful when you rotate the mass.  Be
aware of your surroundings so nothing is inadvertently hit by the rotating
mass.

· 
Enlist
the aid of a partner to time your experiments.

*Complete
this column after performing the calculation in question 5 below.

Based
on your results from the experiment, please answer the following questions:

1. Draw a circle
   to represent the path taken by your rotating mass. Place a dot on the
   circle to represent your rotating washer. Add a straight line from the dot
   to the center of the circle, representing the radius of rotation (the
   string). Now label the direction of the tangential velocity and the
   centripetal force.

1. Here is a
   diagram of our experimental situation:

Please add vectors to create a
free-body diagram.  Assume that m₁ is rotating at a speed v with a constant radius R.

The following forces should be
included in your free-body diagram:

· 
Tension
in the string

· 
Centripetal
force on the rotating mass

· 
Gravitational
force on the hanging mass

Hint: Each mass experiences
the tension in the string.  The string
tension ultimately cancels out when you solve Newton’s equations of motion for
both masses.

3.  From your free-body diagram, write the sum
of the forces experienced by mass m1. From your free-body diagram, write the
sum of the forces experienced by mass m2.

(For the equation for mass m1,
use the following relations to replace the speed, v: v = wR,
where R is the radius of rotation w
= 2p/T, where T is the period of rotation.)

In question 4 you will
solve the two above equations to obtain the period of the rotating system in
terms of the radius of rotation and the two masses, m1 and m2.

1. Solve the
   above equation for the period, T.

1. Now let’s
   look at the special case of our experiment: 4m₁ = m₂.  Show that our general expression for the
   period T becomes:

Using this expression for the
period, fill in the theoretical period in the results table.

1. How did the
   period of rotation vary as you changed the radius? How does the angular
   frequency change?

1. Were your
   experimental values close to the theoretical values? How could you improve
   the experiment to reduce error?

Cyber Threats, Offenders, and Crimes

Develop a comprehensive Microsoft PowerPoint presentation of 12—15 slides for the chief of police. The presentation will be used as part of an educational program for the government officials and the public in an effort to obtain funding for the new cyber investigative unit. Your presentation should describe the growth and emergence of personal computing and the Internet. Include the following in your briefing:

• A description of the types of threats to computer users and Internet surfers globally.
• The types of offenders and the digital forensic crimes they commit and threats they pose to your community.
• The areas where digital forensics is of utmost help in catching the offenders.
• Analyze how has digital forensics been used in a recent case to either assist in convicting or acquitting the defendant.
• Explain types of crimes committed using computers and the Internet in your community.
• Analyze profiles of the offenders and the crimes they commit.
• What role does digital forensics play in detecting, solving, and successfully prosecuting perpetrators of computer and Internet-facilitated crimes in your jurisdiction?
• Provide at least one recent case in your jurisdiction or nearby in which computer forensics was instrumental in assisting in the conviction or acquittal of the defendant.

Present the additional information in the Notes section in your presentation.

Support your responses with examples.
