Choose 3 journal articles you think will be useful as references for your formal lab report paper. You may use review articles or research articles. You might try typing in a keyword for your topic and the word “review”.   Obtain copies either from the library or from an on-line resource. In the space provided below, explain in no more than 5 sentences per article why you feel the article you have selected is appropriate for your paper. Just because your key word appears in the title does not automatically mean the paper will be useful for your report. Briefly state how you will use it in your report. Attach a copy of each article to the assignment before handing it in. Directions on how to access electronic journals through the University of Houston Library are at the end of this document. If you cannot download an article you desire directly from the PubMed website, try through the University of Houston Library electronic journals collection. If the university does not have the electronic version on file, you will have to go to the library and copy it on a copy machine (the old-fashioned way). If you cannot obtain a copy of the article, you can place a request through interlibrary loan at the service desk at the library or you will need to find another article.

Thanks everyone!

In the Python:

Note 1: You may not use these python built-in functions:

sorted(), min(), max(), sum(), pow(), zip(), map(), append(), count() and counter().

(7 points) unique.py: A number in a list is unique if it appears only once. Given a list of

random numbers, print the unique numbers and their count. Print the duplicate numbers and

their count.

Sample runs:

Enter the size of the list : 7

[8, 2, 6, 5, 2, 4, 5]

There are 3 unique numbers: 8 6 4

There are 2 duplicate numbers: 2 5

Sample run:

Enter the size of the list : 7

Two 50 ?? long, thin parallel straight wires (grey) are connected at their ends by metal springs. The mass of each thin wire is 1.0 ?. The upper wire is connected to the ceiling by (non-conducting) stiff rods. Each spring has an equilibrium length of 5.0 ?? and a spring constant of ? = 0.50 ?/?. A steady current ? runs clockwise through the wire-spring loop as indicated by the arrow. At equilibrium, the lower rod hangs at a level 6.0 ?? below the upper wire. Find the magnitude of the current. You may ignore the magnetic fields generated by the springs, and you may approximate the magnetic fields generated by the wires as those from long, straight wires

Two blocks, of weights 3.5 N and 5.8 N, are connected by a massless string and slide down a 39° inclined plane. The coefficient of kinetic friction between the lighter block and the plane is 0.064; that between the heavier block and the plane is 0.30. Assuming that the lighter block leads, find (a) the magnitude of the acceleration of the blocks and (b) the tension in the string.

In the figure below, the hanging object has a mass of m₁ = 0.410 kg; the sliding block has a mass of m₂ = 0.765 kg; and the pulley is a hollow cylinder with a mass of M = 0.350 kg, an inner radius of R₁ = 0.020 0 m, and an outer radius of R₂ = 0.030 0 m. Assume the mass of the spokes is negligible. The coefficient of kinetic friction between the block and the horizontal surface is ?_k = 0.250. The pulley turns without friction on its axle. The light cord does not stretch and does not slip on the pulley. The block has a velocity of v_i = 0.820 m/s toward the pulley when it passes a reference point on the table.

(a) Use energy methods to predict its speed after it has moved to a second point, 0.700 m away.
m/s

(b) Find the angular speed of the pulley at the same moment.
rad/s

Q: Why do you want to be a CPO peer educator? CPO stands for Center for Prevention outreach. I would love someone with experience to provide insights to their personal story.

Q: What experience do you have talking about health and wellness with your peers (high school or college)? Again I hope someone with experience provide insights.

Much appreciation, thank you!

Taking a test on "Inheritance" in C++ tomorrow. So far we have learned about classes, structs and arrays and strings. We will be provided with coding prompts and have to hand write codes that show examples of inheritance (most likely including some of the earlier concepts as well).

I would like some code examples such as this to study and look over with comments please.

At 700 K acetaldehyde decomposes in the gas phase to methane and carbon monoxide. The reaction isCH3CHO(g)?CH4(g)+CO(g)
A sample of CH3CHO is heated to 700 K and the pressure is measured as 0.20 atm before any reaction takes place. The kinetics of the reaction are then followed by measurements of total pressure and these data are obtained:

Rate law --> Rate=??PCH3CHO?t=4.510?4atm?1?s?1PCH3CHO2

Find total pressure after 1.1710⁴s

An unknown pollutant gas has contaminated one of your samples of Ne(g). You test your Ne sample, at constant T and P and find that it effuses through a balloon 3.87 times more rapidly than a pollutant. What is the molar mass of the pollutant gas?

Consider two individuals with the same income and probability of experiencing an accident that would cost them $15,000 in medical expenses. The first individual has the utility function U=ln(Y) and the second has the utility function U=ln(Y)+10. How would their willingness to pay for an insurance policy to cover all of their medical expenses differ between the two individuals?
