So, I was reading my textbook in the section regarding net torque, and they gave an example of a seesaw with one person at each end, and they said that there is a net external torque due to the force of gravity on each person. I completely understand that; however, when I was reading another section of my textbook, they were talking about the conservation of angular momentum, which only happens when the net torque is zero. So they gave an example of a circular disk that rotates freely in a horizontal plane about a frictionless, verticle axle. On top of that, there is a person who walks slowly from the rim of the disk towards the center. The textbook modeled this problem as conservation of angular momentum problem, but why? Isn't the weight of the person causing an external torque just how the weight of the two people in the seesaw caused a net external torque?

Correlation should not be equated with causation. The textbook presented the example of height and weight to illustrate that point. Based on your life and work experiences and observations, give three additional examples of correlations that would be misleading if they were explained using a cause-effect logic, in other words, examples of two variables that may be correlated but do not cause each other. Please use correlation language to describe your examples (see textbook).

A 1.70-m-long barbell has a 25.0 kg weight on its left end and a 37.0 kg weight on its right end.If you ignore the weight of the bar itself, how far from the left end of the barbell is the center of gravity? Where is the center of gravity if the 9.00 kg mass of the barbell itself is taken into account?

ABCable, Inc. is a publicly traded cable provider. Among its current services are providing cable services, including television, Internet access and local telephone service. ABCable experienced rapid growth in all markets beginning in the late 1990s and continuing through now.
While revenues continue to grow, income is showing signs of declining to a level beneath that expected by analysts who follow the company. In an analysis of why, Sally Bens, financial vice president, discovered that maintenance of cable systems has become an increasingly large cost—particularly in new cable coverage areas. She pointed out to Bill Jones, the president, that in the relatively new areas maintenance is high, particularly when viewed from the perspective that the areas currently have few customers. Jones has suggested that it doesn’t seem right to face such high expenses when “everyone knows we will have a larger customer base in a few years in those areas.”
Shortly thereafter, Bens and Jones decided to transfer out of Cable Maintenance Expense and into the Capitalized Cable account enough of these expenses to enable net income to meet analysts’ forecasts. Documentation in some cases was created indicating a correction of an error and in some cases no documentation was created to support the entries.
Subsequently, these types of transactions were posted quarterly, on an “as needed” basis. Bens rationalized that it was indeed unfair to expense so much of the maintenance cost in rapidly growing areas. Jones didn’t give it a lot of thought other than to periodically remind Bens of how important meeting EPS growth rates was.
The above scheme does not meet generally accepted accounting principles and led to materially misstated financial statements. Under generally accepted accounting principles, these transactions should have been expensed. Thus, the ABCable overstated assets and income.
1.Is this an example of fraudulent financial reporting or misappropriation of assets?
2.The Institute of Internal Auditor’s guideline requires a number of inquiries of management, the audit committee, internal auditors, and others. Which, if any, individuals responding to these inquiries might be likely to reveal this scheme to the auditors?
3.This is an example of management override. What types of procedures does IIA standard practices prescribe for management override? Which, if any, of these procedures would have a possibility of detecting the scheme?
4.In the following given table, which fraud risk factors are present in this case? List them and cite the example from the case.

This is for Macro-Econ: I just need to double check my answers on item d. and item e.
When increasing the annual output of potatoes from 600 to 800 pounds the country has to lose 200 pounds of fish because 500 pounds of fish – 300 pounds = 200 pounds. Therefore, 200 potatoes = 200 fish. The opportunity cost of potatoes with respect to fish is 200/200. So, opportunity cost of potato = 1 fish.
When the output increases from 200 to 400 pounds of potatoes there is an increase of 200 pounds of potatoes and the country must sacrifice 50 units of fish (650-600=50). If the production of potatoes is to increase, then the production of fish should be decreased by 50 pounds.
c. What is the opportunity cost of increasing the annual output of potatoes from 200 to 400 pounds?
d. Can you explain why the answer to parts b and c are not the same?
e. What does this imply about the slope of production possibility frontier?
