A flat metal belt, made of Beryllium-Copper (BeCu), is Sf = 375 MPa and transmits at 8,84 rpm and 8.25 kW of power. The distance between the two spindle axes on the same horizontal plane is 935 mm and belt life is 10⁶ turns. The friction coefficient between the belt and the pulley will be 0.34, the operating coefficient is 1.41, and the design coefficient will be 1.55. The diameter of the translated pulley is 3.25 times the diameter of the motor pulley. The belt thickness is 0.20 mm and in case of using a minimum diameter pulley, calculate the belt width and length. The belt width should be 5 mm and its multiples. Calculate the pretension force to be applied

A protein solution was placed in an analytic centrifuge and spun until equilibrium was reached. The measurement was then repeated. But it was realized, too late, that prior
to the second run, the protein had been denatured. The average size of a denatured protein is larger than that of a native, compact protein. (a) Do you expect the distribution of molecules to be the same, at equilibrium, for the two different runs? Explain. (b) The time that it takes to reach equilibrium depends on the sedimentation constant of the molecules. Which run will reach equilibrium faster, the one with the native protein, or the one with the denatured protein? Explain how you imagine the sedimentation process of the two molecules.

What would happen to the pH as Ksp values increase? And Why?

Many conditions of the airways feature common symptoms, caused by divergent mechanisms that underpin what for all intents and purposes can be identical symptoms to the untrained eye. Compare and contrast asthma to the following:

1- Tuberculosis

2- Interstitial lung disease

3- Hypersensitivity reactions

List their causes, discuss the clinical presentation of each condition, explain the innate and adaptive immunological status underpinning each disease, and outline the current and emerging options for therapy.

Many organizations are engaging in mass layoffs (or reductions in force) due to the effects of physical distancing measures.

What are the effects such a decision can have on employees and employers?

What are the alternative options that organizations might consider?

What are the advantages and disadvantages of layoffs versus any alternative options that might be available?

For the third time in the past 5 minutes, Jeremy’s fourth-grade teacher has had to tell him to sit in his seat and keep his hands to himself. It is as if Jeremy’s feet are attached to springs. He doesn’t walk; he bounces. He doesn’t sit; he squirms. It’s not just the motor activity that sets him apart from the rest of the class: Jeremy also has a motor mouth. He talks incessantly. He can’t resist sharing his ideas with the class, whether they are welcomed or not. As soon as he thinks about them, regardless of whether the time is right, Jeremy blurts out answers, disrupts the classroom, and adds considerable stress to his teacher’s already stressful job.

   Jeremy is almost the polar opposite of his classmate Leonard. For Leonard, Jeremy’s antics just fade into the background of other classroom stuff. Unlike Jeremy, Leonard is very quiet and rarely participates in classroom discussions, unless the discussions are about something that really interests him. Leonard spends most of his time staring out the window or off into space. The word daydreamer seems to fit Leonard perfectly.

   Leonard always seems to be at least one step behind everyone else. Leonard is rarely on task; he drifts off in the middle of assignments; often he has to be reminded to return toe arth. Leonard is doing poorly academically. He just doesn’t seem to tune in to whatever channel the rest of the class is on. Initially, the teacher thought that Leonard was a slow learner, until the class began to discuss different computer programs. The teacher was shocked at Leonard’s sophisticated knowledge base and expertise in the area. That was when his teacher began to think that there was something else getting in the way of Leonard’s academic success.

   In this case study, Jeremy and Leonard share more than the same classroom and same teacher. As incredible as it might seem, they both probably share variations of the same disorder: attention-deficit/hyperactivity disorder (ADHD). How can two children who seem so different fall into the same diagnostic category?This is a question that has plagued theorists for the past 100 years. Although ADHD is among one of the most prevalent disorders in childhood, it continues to challenge professionals. It has been a topic for considerable discussion and controversy, especially regarding the over prescription of stimulant medications (Diller,1996).

In a 100 words or more:

Provide a discussion of the co-occurring clusters for childhood and adolescence symptoms and features.

1. The primary of a step-up transformer connected to a 120 V source has 200 turns. If the output is 480 V, how many turns does the secondary have?

2. The primary of a step-down transformer connected to a 240 V source has 1500 turns. The secondary has 200 turns.   What is the output voltage of this transformer?

3. A laptop computer requires 24 volts to operate properly. A transformer with 600 turns in the primary needs to have how many turns in the secondary to operate the computer from a 120 V source?

4. If the output current for the transformer in the previous problem is 4.5 A, calculate the input current.

5. A transformer has an input of 24 V and an output of 36 V. If the input is changed to 12 V what will the output be?

6. A model electric train requires 12 V to operate. When connected to a household voltage of 120 V, a transformer is needed. If the primary coil has 250 turns, how many turns must the secondary coil have?

7. A transformer has 25 turns in the primary coil and 200 turns in the secondary coil. If 24 V is connected to the primary coil and a 20-Ω device is connected to the secondary coil, calculate the current in Amperes passing through the device.

8. Neon signs need 12,000 V to operate. If a transformer operates off a 240 V source and has 1000 turns in its primary coil, how may turns must the secondary coil have?

9. A power of 200 kW is delivered by power lines with 48,000 V difference between them. Calculate the current, in amps, in these lines.

10. If the lines in problem #9 above, have a resistance of 100-Ω, calculate the change of voltage along each line.

Describe the basic ideas included in Kohlberg's theory of moral development (see video lecture and Barkan, p. 114). How is moral development related to crime and deviance according to Kohlberg? Compare and contrast Moral Development theory with one other psychological explanation for crime

The superintendent of the Middletown school district wants to know which of the districts three schools has the lowest rate of parent satisfaction. He distributes a survey to 1,000 parents in each district which asks if the parent is satisfied with their child’s school, and all of these parents respond. Here are the results school

a. Percentage the table in a way that best answers the superintendent’s question

b. Calculate the percentage point difference between the rate of satisfaction at school A and school B, between the rate of satisfaction at school A and school C, and between the rate of satisfaction at school B and school C. Explain what these numbers mean in English.

c. Calculate the chi square value of this table

d. Are the differences shown in this table statistically significant at the 95% level?

e. Based on what you found in (b) and (d), and using your own judgement, how would you answer the superintendent’s question?

Most modern text editors are able to give some statistics about the text they are editing. One nice statistic is the average word length in the text. A word is a maximal continuous sequence of letters ('a'-'z', 'A'-'Z'). Words can be separated by spaces, digits, and punctuation marks. The average word length is the sum of all the words' lengths divided by the total number of words.

For example, in the text "This is div2 easy problem". There are 5 words: "This"is"div"easy" and "problem". The sum of the word lengths is 4+2+3+4+7 = 20, so the average word length is 20/5 = 4.

Given a text, return the average word length in it. If there are no words in the text, return 0.0.

Input
The first line will contain the text of length between 0 and 50 characters inclusive. Text will contain only letters ('a'-'z', 'A'-'Z'), digits ('0'-'9'), spaces, and the following punctuation marks: ',', '.', '?', '!', '-'. The end of text will be marked with symbol '#' (see examples for clarification).

Output
Output should contain one number - the average length. The returned value must be accurate to within a relative or absolute value of 10^-9.

example:

input:

This is div2 easy problem.#

output:

4.0
