A student sits on a rotating stool holding two 3.2-kg objects. When his arms are extended horizontally, the objects are 1.0 m from the axis of rotation and he rotates with an angular speed of 0.75 rad/s. The moment of inertia of the student plus stool is 3.0 kg · m2 and is assumed to be constant. The student then pulls in the objects horizontally to 0.36 m from the rotation axis.

(a) Find the new angular speed of the student. rad/s

(b) Find the kinetic energy of the student before and after the objects are pulled in. before & after (J)

As schools moved to the remote online training model some faculty were requested to learn new online skills. The effectivity of the training was evaluated with a “before and after” test of the teacher’s evaluation of their skills. The scale was a 10-point Likert scale and the teacher was asked to give a “pre” before and “post” after the training. A small sample of 10 teachers is in your data files at the end of this test. Use an alpha of .05. Run the proper analysis of “before and after” and answer the following questions.

Give the following:

1- Mean pre-test.  

2- Variance pre-test   

3- Mean post-test   

4- Variance post-test

5- Number of observations   

6- Number of teachers surveyed in this test

7- tStat    

8- P(T<=t) one

9- Conclusion reached:

The following information is extracted from several articles2 about oil market. An intensifying oil price war between Saudi Arabia and Russia has created “very painful” market conditions for the world’s largest crude oil producers. International benchmark Brent crude traded at $32.97 Thursday, down almost 8%, while U.S. West Texas Intermediate (WTI) stood at $30.40, around 7.8% lower. Oil prices have almost halved since the start of the year. Last week, Saudi Arabia failed to secure Moscow’s support for deeper output cuts at a meeting of the Organization of the Petroleum Exporting Countries and its allies, known as OPEC plus. OPEC had proposed to deepen cuts by 1.5 million barrels per day and Russia was asked to cut an extra 300,000 bpd. “There was no point in cutting until after everyone understood how sharply demand could fall. We cannot fight a falling demand situation when there is no clarity about where the bottom (of demand) is,” Pavel Sorokin, the Russia’s deputy energy minister, said. “It is very easy to get caught in a circle when, by cutting once, you get into an even worse situation: oil prices would shortly bounce back before falling again as demand continued to fall.” Cooperation between two (Saudi Arabia and Russia) of the world’s three largest oil producers — the third is the United States — appears to be at an end. 2How a Saudi-Russian Standoff Sent Oil Markets Into a Frenzy. 9th March 2020. New York Times Russia to OPEC - deeper oil cuts won't work. 12th March 2020. Reuter The losers — and even bigger losers — of an oil price war between Saudi Arabia and Russia. 12th March 2020. CNBC

a) With aid of diagram, explain how the fall in crude oil demand affect the output of OPEC plus members.

b) Discuss why Russia refuse to follow Saudi Arabia’s proposal to cut crude oil production with aid of diagram.
