Oil Prices Fluctuating In the Middle East

Introduction Oil being a commodity is subject to high levels of fluctuations as opposed to the stable investments like bonds and stocks. In particular, Organization of Petroleum Exporting Countries (OPEC) plays a significant role in influencing the prices of oil across the globe. As a result, OPEC controls around 40 percent of the global supply of oil by setting the production levels that caters for the world demand and it can determine the prices of gas and oil by reducing or raising the levels of production. At a particular point in time, OPEC vowed to maintain the prices above $ ...

In this case, we use the monthly returns of the two indexes for the seven-year period between 6th May, 2009 and 5th May, 2016. The monthly return are determined by comparing the current price with the previous month’s price. The monthly returns are then used to determine the average monthly return and the monthly standard deviation.

Average monthly return = 1.2047% or 0.012047 Monthly standard deviation = 4.4024% or 0.044024 Annual return = (1 + monthly return)12 – 1 = 1.01204712 – 1 = 1.1545 - 1 = 15.45% Annualised standard deviation = Monthly standard deviation × √12 = 0.044024 × √12 = 0.044024 × 3.4641 = 0.1525 = 15.25%

I was atop the highest peak of Mt. Everest when I slipped at the edge of the ravine. The feeling of fear, helpless surrender to the Divine Power enveloped me while I free fall to an immense space feeling an eerie cold downwards. As I surmised that distance to the ground started getting near, I felt shortness of breath. Suddenly, I awoke with my heart pounding incessantly and perspiration was all over my body. From then, I thought, letting go had negative repercussions. I would never let go. The affirmation was short lived. Sooner, more than later, I was ...

The experiment aims at determining the value of gravitational acceleration (g) using simulation of objects under free fall, vertical acceleration, and objects in a projectile motion. Bodies fall under the influence of gravitational forces. The force mg acts on the body. However, when such objects are falling under the influence of gravity, such motions are referred as free fall. The assumption underlying free fall motions is that they do not encounter air resistance. The motion of free falling objects is characterized by a downward acceleration. The equations of motions are modified as shown below. V (t) = -gt +V0
