Consider a microscopic springmass system (with a single spring and a single mass) whose spring stiffness is k = 50 N/m and mass is m = 4 × 10−26 kg. a. What is the smallest amount of vibrational energy that can be added to this system? b. In a collection of microscopic oscillators, the temperature is high enough that the ground state and the first three excited states are occupied. What are the possible energies and wavelengths of the photons emitted by the oscillators.

I want to know how to solve the following in excel. What is the x value and what is the Y value using the data table below?

Wal-Mart is the second largest retailer in the world. The data file (Wal-Mart Revenue 2004-2009.xlsx) is posted below the case study one file, and it holds monthly data on Wal-Mart’s revenue, along with several possibly related economic variables.

A. Develop a linear regression model to predict Wal-Mart revenue, using CPI as the only independent variable.

B. Develop a linear regression model to predict Wal-Mart revenue, using Personal Consumption as the only independent variable.

C. Develop a linear regression model to predict Wal-Mart revenue, using Retail Sales Index as the only independent variable.

D. Which of these three models is the best? Use R-square values, Significance F values, p-values and other appropriate criteria to explain your answer.

E. Generate a scatter plot, residual plot and normal probability plot for the best model in part (d) and comment on what you see.

The energy from compounds like glucose can be harvested to generate ATP in aerobic respiration. This is a complex process that involves many chemical conversions.

Describe the main processes that occur. Include all critical concepts in your answer, and where in the cell they occur. You do not need to describe the individual chemical reactions, but do describe the most important elements of each part of aerobic respiration.

Make sure it is clear from your description that you understand how the different processes interconnect, and how ATP eventually is generated. Your answer should be approximately 200 words. In the answer terms like glucose, pyruvate, cyclical behavior of the citrate cycle, NAD+, OXPHOS complexes, proton motive force etc. should be included/ discussed.

Essay answers are limited to about 500 words

HopHeart Brewery is considering 3 different bottling machines. It is expected that each machine will be replaceable at the same cost when their useful life ends. The details of the machines are as follows: Machine X has a useful life of 6 years. It costs $10,000 to purchase and $2,000 per year to maintain. Machine Y has a useful life of 12 years. It costs $15,000 to purchase, and $1,000 per year to maintain. Machine Z has a useful life of 8 years. It costs $20,000 to purchase, and $200 per year to maintain.

a. What is the appropriate planning horizon for analyzing these choices?

b) Using the planning horizon from part a, analyze the present worth of the cost of each alternative if HopHeart has a MARR of 9.8%/year.

Machine X _____________

Machine Y _____________

Machine Z _____________

c.) How much heat energy is transferred, and in which direction?

d.) From helium to oxygen or oxygen to helium?

e.)What is the final temperature? Express your answer using three significant figures and in Kelvin.

The Harrison Group Life Insurance company computes annual policy premiums based on the age the customer turns in the current calendar year. The premium is computed by taking the decade of the customer’s age, adding 15 to it, and multiplying by 20.

For example, a 34-year-old would pay $360, which is calculated by adding the decades (3) to 15 and then multiplying by 20.

Write an application that prompts a user for the current year then a birth year. Pass both to a method that calculates and returns the premium amount, and then display the returned amount.
