How would you go about finding the %RAD for a titration experiment?

When running in the dark, some people recommend that you look to the edge or side of where you are going (and not directly at it). Is this good advice? Why or why not? Explain how your recommendation is based on the biology of the retina and/or brain.

Berger’s Lawn Maintenance Inc. is considering accepting 20-year property maintenance contract from the City of Kingston. The contract would require Berger’s to acquire new landscaping equipment, including a new trencher and excavator machine, amounting to a total purchase cost of $500,000 plus installation costs of $50,000. Other data relating to the contract are as follows: Annual incremental revenues from the contract $200,000 Annual maintenance cost for the new equipment $80,000 Additional maintenance costs at the end of year 10 $300,000 Salvage value of the equipment at termination of the contract $20,000 If the contract was accepted, several old, fully depreciated pieces of equipment would be sold at a total price of $30,000 upon signing the contract. These funds would be used to help purchase the new equipment. For tax purposes, the company computes CCA deductions using the maximum rate of 20%. The company requires an 11% after-tax return on all equipment purchases. The tax rate is 30%.

Required: Compute the net present value of this investment opportunity. Round all dollar amounts to the nearest whole dollar. Would you recommend that the contract be accepted?

FASTQ to FASTA converter: Implement a FASTQ to FASTA file format converter in python (the input is a FASTQ file and the output is a FASTA file)

What is the mass per repeating unit of PET (in g/mol)? explain why this number should be used ffor determning limiting reagent and yield and not the actual molecular weight of the polymer (which is >> 10,000 g/mol). I know that the mass per repeating unit of PET is 192 g/mol.

What were the factors that caused the field of International Relations to flourish in the West?

Prior to WW1 the study of International Relations was conducted in two loosely organized branches of learning, name and explain them

Write a Python program that prints 20 “random” license plate numbers, each one consisting of three randomly-chosen digits followed by three randomly chosen upper-case letters. The first digit cannot be zero. Sample output might look like: 382 HGK 819 YEU

A vapor mixture of -butane (B) and -heptane (H) contains 40.0 mole% butane at 80°C enters a condenser at a rate 4 kg/s. Liquid and vapor product streams emerge from the process in equilibrium at 40◦C. The vapor product has a 45.0 mole% butane composition. Determine: a. The pressure in the condenser b. The composition and flowrate (mol/s) of the liquid stream c. During operation, the system contains a 3m depth of the liquid phase (S.G. = 1.41) at any given time. If the maximum pressure the vessel floor joints can handle is 1 bar, will the tank rupture?

APPLICATIONS (GOOGLE CHROME, MICROSOFT EDGE BROWSER AND THUNDERBIRD MAIL APPLICATION) How does each of them address patch management? Visit their Web sites to determine facilities they have to alert users to new vulnerabilities. Then look at three competing products (for example, if you are examining Microsoft Office, then look at OpenOffice) and evaluate their patch management system. What did you discover? Are the patch management systems adequate? During your research, be sure to answer the following questions

Please answer the following question:
Window glass is colorless in the usual thickness used, but appears slightly green when viewed from the edge due to small amounts of Fe³⁺ . Why is this so?

How do you prepare 25 ml of 8.5 mM NaCl from a 20% NaCl stock? (Hint: convert 20% to g/ml then to molar)

Background

As seen on this picture of the cosmic microwave background (take from the Wikipedia entry on the very same topic) there exists irregularities in the distribution of matter: Cosmic microwave background. Boom baby!

To my knowledge, this is because the Universe wasn't formed with all the matter (or whatever you should call whatever existed right after the big bang) in a completely regular pattern (or if it was the case that anti-matter had this big fight with ordinary matter after the Big Bang, it's really not that important I guess), and I guess this is the reason why we have a highly diverse universe today, inhabited by galaxies, black holes, and Justin Bieber.
Question

What would the Universe look like if there were no irregularities in it from the get-go? Would we have a big massive black hole in the middle (if one even can talk about a middle), would the Big Bang never happen, or have I just misunderstood the whole thing, making my question completely nonsensical?

1. A charter flight charges a fare of $200per person plus an additional $4 per person for each unsold seat on a plane that holds a maximum of 100 passengers. Let x represent the number of unsold seats.

a)Express the number of passengers on the flight as a function of x. Call this functionQ(x).

b)Express the price per ticket on the flight as a function of x. Call this functionP(x)

c)Express the total revenue received for the flight as a function of x. Call this functionR(x)

d)Find the number of unsold seats that will produce the maximum revenue as well as what the maximum revenue is (rounded to the nearest cent). Explain how you found your answer using complete sentence

For each pair of substances determine which has the higher entropy per mole of substance.

a. H2O (s) at 200 K or H2O(s) at 298 K.

b. H2(g) at 298 K, 2.0 atm or H2(g) at 298 K, 1.0 atm.

c. H2(g) at 298 K, 5.0 L or H2(g) at 298 K, 1.0 L
