The following 13 short essay questions are designed to evaluate critical thinking/reasoning skills. You do not need to answer all of the questions. What you need to do is choose 2 the following questions to answer (correctly number which questions you chose). If you answer more than two questions, only the first two will be graded. (5 pts. each) 1) Describe the process by which Earth formed, starting with the Big Bang and ending with today (you will need to mention some “specifics”). 2) Describe the formation of Earth’s ocean (you will need to mention some “specifics”). 3) Outline the conditions necessary for a planet to maintain an ocean of liquid water permanently. 4) Describe the events that occurred during the expeditions of Captain James Cook that contributed to scientific oceanography (you will need to mention some “specifics”). 5) Outline the many different experimental samplings conducted during the Challenger expedition. 6) Discuss how satellites are used in oceanography (you will need to mention some “specifics”). 7) Describe the concept of isostatic equilibrium (you will need to mention some “specifics”). 8) Explain plate tectonics theory (you will need to mention some “specifics”). 9) Outline how the formation of the Hawai’ian Islands contributed to the evidence of plate tectonics (you will need to mention some “specifics”). 10) ​Discuss how hydrothermal vents are believed to form. 11) Compare and contrast the occurrence of trenches in the Pacific Ocean with the Atlantic Ocean. 12) Explain why biogenic marine sediment has been found on the top of mountains.​ 13) Describe the movement of a turbidity current and the resulting sediment deposit (you will need to mention some “specifics”).

At one point in a pipeline, a fluid’s speed is [v] m/s and the gauge pressure is [P] kPa. Find the gauge pressure at a second point in the line, [h] m lower than the first, if the pipe diameter at the second point is half that at the first. The density of fluid is

A wheel is spinning and has a counter-clockwise angle as a function of time given by

 (7 pts) Part c on Question 17

If Luke can bake bread at a lower opportunity cost than Jason, and Jason can produce paintings at a lower opportunity cost than Luke, it follows that

A lower level of leverage means that the firm has a lower level of equity than debt?

A wheel rotates about a fixed axis with an initial angular velocity of 20 rad/s. A constant angular acceleration of 2 rad/s2 us used to increase the angular velocity to 40 rad/s. How many revolutions does the wheel turn in this process?

A [ma] g bullet moving horizontally strikes and remains in a [mb] kg block initially at rest on the edge of a table. The block, which is initially [h] cm above the floor, strikes the floor a horizontal distance of [R] cm from its initial position. What was the initial speed of the bullet? Please give your answer in units of km/s.

A firm can increase ROE (NI / common equity) by which of the following?

A 150 kg block is being pushed horizontally by a constant force F of  [x] Newtons. Determine the constant acceleration (m/s2) that would result if the coefficient of (kinetic) friction between the floor and the block
