Orbital

mass of a massive object, the following is needed, Newton’s gravitational law (F = ma = mv2/r). Newton’s gravitational law can be used to calculate the mass which is represented by (M). This can be calculated if the velocity represented by (v), at orbital radius represented by (r), is known for the equation. When these two laws are put together they create the formula M = v2 r / G what G represents is the gravitational constant (6.673 X 10 – 11 m3 Kg – 1 s – 2). For a circular…

There are metallic bonds between metals that affect their properties. Valence electrons from orbitals s and p delocalize to form a “sea” of electrons which makes up the metallic bond. All metals can conduct electricity to different extents. Electrical conductivity arises from the movement of electrons. Metals have valence electrons that are free…

Success and failure, even in the smallest of things affects us in ways we never thought they would. Failure, as much as it hurts, is an important part of life. Not only is it imperative to know how it affects us, but also how we can use it to better us, instead of bringing us down. A study done (Madsen, P. M., & Desai, V., 2010) to see if organizational performance is driven by learning from success found that failure is usually more beneficial for people in the long run. Instead of feeling like…

Though the phenomenon may reach back further, I can remember clearly that since high school, I viewed every activity I chose, every project I undertook, and every class I took from the perspective of a future healthcare professional. On January 2, 2015, my family and I were leaving my childhood friend’s house after a dinner. As we drove past my friend’s house, I waved a bittersweet goodbye to her, as we were both getting ready to begin our second semester of college in a week. Little had I…

The existence of the Kuiper Belt was hypothesized by Gerard Kuiper in 1951. Kuiper described an expanse of icy space material beyond Neptune as the only explanation for short-lived comets. However, that anomaly was not the sole phenomenon the Kuiper Belt and its contents helped explain. The Kuiper Belt’s primordial origins have established it as one of the most helpful tools to aid in learning more about the solar system’s beginning. Its existence debunks the original theory of the belt’s…

Climate Science 1 Day In today’s time there is something called forcing factors which is the tilt of the Earth's axis which creates seasons but other factors that may impact climate systems are such volcanic aerosols which can cool climate and shorten growing seasons. Some instruments used to track climate patterns are thermometers, rain gauges, and stream gauges. Paleo proxies such as tree rings and cores from corals and ice caps also provide information on a resolution in terms of…

Obsessive compulsive disorder(OCD) is anxiety disorder that people have unwanted thoughts, ideas, or sensations(obsessions) that will make them want to something repetitively. Some common compulsive disorders are double checking things to see if they're good or checking in on loved ones to see if they are safe. A lot of people do these things but to be classified as having Obsessive Compulsive Disorder the patient compulsions need to be so extreme that it interferes with there important actives…

When it comes to hand drawings, we can not ignore the contributions made by Leonardo Di Serpiero da Vinci. He is a thoughtful, knowledgeable, versatile painter, astronomer, inventor, architect. He is good at sculpture, music, invention, construction, mathematics, physiology, physics, astronomy, geology and other subjects. He is not only versatile, but also diligent and prolific. It is reported that there are about 6000 pages of his manuscripts well preserved. Most of his scientific research…

Immediately the external tank was jettisoned to burn in the atmosphere, the spacecraft’s Orbital Maneuvering System engines came to play. They provided the thrust required for the crews rendezvous as well as providing up to 1,000 pounds of propellant directed to the craft’s aft control system (Gaston,1991). Almost spontaneously, both orbital maneuvering system engines raised the orbiter to a predetermined elliptical orbit saving the crew from this ominous stage of…

Mark Watney is having the time of his life, and then it turns into a nightmare. Mark is on a trip to Mars with his crew. When they arrive on Mars, they decide to start building the hab. While they were finishing the hab they noticed the radar said there was a big sand storm. The sand storm was getting closer and dangerous so they were trying to get to the rocket ship. They were in such a rush they didn’t notice Mark was not there until they got to the ship. They had to leave Mark behind because…
