Question options:

An electron and a proton are a distance r = 7 × 10^-9 m apart. How much energy is required to increase their separation by a factor of 3?

Well this is pretty noobish question and I am not sure how to ask.
When We talk we don't talk in an uniform frequency. Then how can one measure frequency of ones sound/voice ?
I am asking this cause several times I've heard people to say this is his/her frequency of voice. Is this a vague term ? or it has any real meaning ?

Question num. one

Of all the personal and professional attributes that a covenant negotiator must have, which do you consider to be the most important and significant that you must possess? Prepare a list of the attributes that a negotiator should have and indicate the most important in your opinion and why.

Question num. 2

Collective bargaining has long been viewed by scholars as an "art." More recently, however, scholars have begun to see collective bargaining as a "science." Explain your position on this statement. Indicate whether you agree or disagree and say why. Be detailed in your answer. Because some think it is an art and others think it is a science.

Question num. 3

From an employer's point of view, what advantages and disadvantages do you see in reducing a grievance to a formal written complaint. Do you consider that a verbal complaint is better than a formal written complaint? Be specific about the advantages and disadvantages of each modality. Do not forget that your opinion is requested from the employer's point of view

Question num. 4

Why might the management of a company or the union itself prefer not to have an arbitration clause contained in a negotiated collective agreement? What use is arbitration? Do you consider arbitration to be a useful tool for conflict resolution? You would recommend negotiating a collective agreement that does not contain an arbitration clause. Be highly specific in your opinion.

Question num. 5

Generally, collective agreements contain clauses regarding wages and the subsequent adjustments that must be made during the term of the agreement. If you are a union representative and are negotiating an agreement, what would be the elements related to wages that you would negotiate for the benefit of your enrollment. What compensation elements would you include in your agreement as part of your salary definition. What if any would you suggest to address gradual wage increases, namely: percentage increases, performance-based increases, increases based on some economic formula, or increases based on government determinations? Would you prefer a combination of factors? As structuring its clauses related to wages. Be highly specific. Do not forget that you are a representative of the workers.

A high-speed flywheel in a motor is spinning at 500 rpm when a power failure suddenly occurs. The flywheel has mass 38.0 kg and diameter 80.0 cm. The power is off for 25.0 s, and during this time the flywheel slows due to friction in its axle bearings. During the time the power is off, the flywheel makes 160 complete revolutions.

A.) At what rate is the flywheel spinning when the power comes back on? (in rad/s)

B.) How long after the beginning of the power failure would it have taken the flywheel to stop if the power had not come back on? (in s)

C.) How many revolutions would the wheel have made during this time? (in rev)

QUESTION:

Explain why it is important that prices are flexible in our economy? What are the implications if the government started to control prices for products, how would this influence buying?

Researchers are trying to estimate the proportion of patients trying a new experimental drug who experience a skin rash as a side-effect. 245 patients took this drug as part of early research, and these 245 patients are considered representative of the population who would take this drug in the future. 2.86% of these patients reported a skin rash. We would like to construct a 90% confidence interval for the proportion of potential drug users who would develop a skin rash.

What would be the standard error for our sample proportion, using the information we have from our sample to estimate that? Round to 3 decimal places

a 90% confidence interval will go 1.65 standard errors out in either direction. Calculate the lower bound of this 90% confidence interval for the true proportion of drug users who experience a skin rash as a side effect

In the US, the Federal Trade Commission (FTC) is tasked with collecting information from consumers and passing on this information to other administrative bodies and policy makers.While the FTC cannot resolve individual complaints, it aggregates this information and passes it on to relevant agencies so that other agencies and policy makers can formulate laws and regulations.

You went to a used car dealer and purchased a used car (“as-is”) without a warranty contract. Let’s say that you cut them a check for $2500 and drove it off the lot. Within 20 minutes of driving it, the car’s engine dies. You take it to your mechanic, who tells you that the timing belt failed and the engine seized as a result. You now need a brand new engine (worth over $3000)

How might you act to resolve this issue? Are there any laws or regulations that could protect your rights in this situation? Are there any governmental bodies that might help you with this situation? Are there any state or federal governmental representatives that might help you in this situation or even prevent such situations from happening to someone else in the future?

A Rankine power cycle with reheat uses water as the working fluid. The inlet conditions of the
first stage turbine are 14MPa and 600C. All the turbines are known to have isentropic
efficiency of 85%, however the pump is assumed as an isentropic pump. If the maximum
temperature is kept at 600C and the condenser pressure is 6 kPa, by constructing a suitable
plot, show that having more than 2 reheat stages is not practical. (Hint: Take at least three
reheat pressures between 2 to 12 MPa)
Note: You may construct the plot on Microsoft Excel or manually on a graph paper. However,
all the calculations involved must be performed manually, in details and must be shown clearly.

Consider the hydroboration of 1-pentene. Predict the major outcome of this reaction through a transition state analysis and construct a reaction coordinate diagram to justify your answer. Note: the oxidation step after hydroboration does not have any impact on regioselectivity.

The minimum stopping distance for a car from an initial 100 km/h is 60 m on level ground. What is the stopping distance when it moves (a) down a 10 degree incline; (b) up a 10 degree incline ? Assume that the initial speed and the surface are unchanged.

Write a Java method that removes any duplicate elements from an ArrayList of integers. The method has the following header(signature):
