The main reason of the climate change is the green house gases that are the result of burning of fuel and other resources of the earth to attain power. The increases in the emission of the green house gases given rise to the temperature of the earth, which became one of the biggest threats to the habitat of the earth like the many species of the coral reefs, are vanishing due to the rise in temperature.
For each configuration, we suspended a number of masses on the spring system and measured the displacement of the setup from its original position. We’d then find out the effective spring constants graphically by plotting the graph between the force applied and displacement of the system.

It is undeniable that the world has been largely dependent on fossil fuels as the primary source of energy to drive various aspects of the economy. However, fossil fuels are non-renewable hence necessitating the need to come up with a better source of energy. Nuclear energy is one of the most viable alternatives for fossil fuels due to its efficiency.
One of the most amazing part of creation would be the solar system. Today, the solar system is still a mystery to some people while those that understand what it really is are awed by its vastness. First of all, the solar system is made up of the star which we call the Sun; many planets namely Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus, Neptune, and Pluto; and numerous comets, asteroids, and meteoroids.
These fields also build due to heating coils and motors of electronically operated equipment including the ones present in industrial or automotive engines. In understanding the nature of light being one perspective, one ought to have adequate knowledge of electric fields and magnetic fields.
Energy is measured on the earth in the form of both heat and temperature. Temperature is the average kinetic energy of the molecules and atoms of a substance. According to (Gavin 104-7) “The concept of temperature is as fundamental a physical concept as the three fundamental quantities of mechanics—mass, length, and time.
Kibble also adds that laws have been directed on different and various methods and forms, like Lagrangian, Hamiltonian and Newtonian mechanics which are used according to the one gives answers more conveniently and easily.
Water is indispensable to human life but sometimes although there is water, not all of it is potable as it had become heavily polluted. A new sense of urgency is rising as there is now a new concept of “peak water” as a diminishing resource much like “peak oil” but although it is renewable, it is not perpetually inexhaustible.

The paper briefs about the initial problems after the 2009 floods and explains the reasons behind this installation. Furthermore, the paper contains a detailed but simplified explanation of the working of solar cells including the structure of solar cells, the P-N junction and the mobile electron-hole pairs, along with the number of cells which will be needed for the required purpose.
Black Hole.
Black holes are very condensed space objects that were formerly the huge stars, which crumpled inward as a result of the power of their own gravity. Consequently, black holes are extremely thick. A black hole is a section of space-time from which “nothing, not even light, can escape” (Susskind & Lindesay, p.

In other words, ozone is more important than oxygen as far as the sustainment of life forms on earth is concerned. The Ozone layer at the top of the atmosphere prevents harmful ultraviolet radiations produced by sun and other stars from reaching earth. However, manmade activities are causing huge problems to the ozone layer at the top of the atmosphere and the depletion of this layer is currently taking place.

Feynman made a wide array of achievements ranging from the creation of an atomic bomb in the days of the Second World War to his unmatched contributions in the exploration of quantum electrodynamics because of this, Feynman received the Nobel Prize in 1965. Feynman maintained a scintillating method of mentorship throughout his career.
In my surroundings, there are houses everywhere. I step out of my door to see the street. On both sides of the street, there are lines of houses. There is little to no garden area where children can go and play or people can make a picnic, though inside every house, there is a garden or if not that, there is a small space for growing plants at least.
Remote sensing of the atmosphere is very essential for the risk-free navigation of airways and weather forecasting of a region over a particular span of time. The process of remote sensing works on the principle of emission and reflection of electromagnetic radiations through the changing medium of gases present in the atmosphere.
Nuclei are spatially encoded in the read direction by utilizing a pulse and collect sequence. The application of the sequence produces an FID which is read to get the gradient required. Multiple frequencies are produced as the read gradient is applied. The variation of frequencies is linearly connected.
The gravitational force of attraction is described by Newton’s law of gravity. Einstein’s theory of general relativity describes the interaction between space and the matter within it. This theory provides an accurate description of gravity than does Newton’s law. General relativity predicts the existence of gravitational radiation.
Grizzly Bear. The grizzly bear (see Figure 1), whose scientific name is Ursus arctos horribilis, is called grizzly due to the light-colored fur on the back and shoulders, which may be brown, or blonde, or black. However, the fur of all grizzlies are white-tipped, making the fur looked grizzled.

Some say that cell phones are linked to higher occurrences of cancer and other ailments, while other studies report that cell-phone users have no higher rate of cancer than the population as a whole. No study to date has provided conclusive evidence that cell phones can cause any of these illnesses.
(Liboff, 1990) The addition of energy especially heat energy triggers particles to move faster while the removal of heat energy slows the particles down. Hence, if the state of heat energy of a system is known then the speed of its particles can be ascertained to a reasonable extent.
Energy is defined as the ability of one physical system to do work on other physical systems. Energy can neither be created nor destroyed; instead it can only be converted from one form to another. (White, 2009) There are various forms of energy such as mechanical, chemical, heat, potential, kinetic, electrical, electromagnetic energy.
This essay analyzes the two main specific types of current: alternative current and direct current. The direction of the current flow is altered or reversed in the case of alternative current. Direct current is a little different from alternative current because it flows in the same direction all the time and no alteration is done with it like in the case of alternative current.
Consequently the study of exchange rates has emerged as a crucial field of economic research since the last few years. This particular field of research has received a tremendous boost, especially in the era of the Bretton Woods in which the foreign rates of exchange became extremely volatile since the inception of the floating rates of exchange since 1973.
The first aspect introduced is the relationship between GDP and interest rates. Changes in the interest rate have no direct impact on the GDP. Consequentially, the GDP remains stationary at its given level (GDP0 in the diagram below) for all levels of the interest rate. Therefore, a vertical line represents the GDP in the graph.

Such intellectual properties do not belong to the employees who invent them; rather they actually belong to the companies for which the employees create those properties. Pollick (2011) states, “Intellectual property, sometimes abbreviated IP, is a legal definition of ideas, inventions, artistic works and other commercially viable products created out of one's own mental processes”.
It is essential to state that as a result of the economic decisions, during President Reagan’s term, the real GDP growth was observed at 3.2% compared which was higher than both pre and post-Reagan eras. The unemployment rate reached a minimum of 5.5% from 7.5% at the start of the term of President Reagan.
The RR refers to the minimum percentage of their deposits that banks must keep in reserve at a Federal reserve bank. The FFR refers to the rate at which banks lend each other money overnight in order to maintain the reserve requirement. If the FFR is high, banks would be unwilling to lend beyond the reserve requirement and vice versa.
In the United Kingdom, the fast food spending was almost ?9.3 billion in the year 2007. Between 2003 and 2007 the fast food market had shown growth of 15.9% and the annual growth was 4%. The huge growth in fast food industry is initiated by top players such as McDonald’s, KFC and Burger King.
It deals with the desire of personal privacy that concern the transmission of data through the internet. It also involves the practice of presiding over the type and amount of information that is supposed to be unveiled about an individual on the internet and those who can have access to that information (Gina, 2011).
As a medium of exchange, money can be used as an intermediary for trade that helps remove the inefficiency of the barter system. As a unit of account, money serves as a standard numerical unit for measuring the value of goods, services, and other transactions. As s standard for deferred payments, money must be used to settle debts at the future date.
Customer satisfaction in e-banking services and brands is often gauged by the analysis of the frequency of use of these products ahead of traditional banking practices. The reliance an individual would place on E-Banking can to a reasonable extent be assessed by examining the frequency with which clients of a bank use the E-Banking services.
