Earth’s magnetic fields to produce energy The earth is a large magnet that could be used to produce sufficient energy to power the world. However dueto immense size of the earth, it is difficult to construct a device large enough to circumnavigate its orbit.
The proposed energy device would consist of two satellites orbiting the earth at the same height. Parallel strands of copper wires would then run from one satellite to the next. Each of the satellite would then have a long cable connecting it to a ground power station. The cable would be such that it collects or connects the parallel strands of copper wires connecting the two satellites. One of the satellite would act as the negative terminal while the second one will act as the negative terminal. The device will generate electricity through magnetic induction, as the earth’s magnetic field continuously interacts with the copper strands connecting the satellites. The device will be expected to generate constant high-voltage electricity since the earth has a constant rotation and hence constant magnetic flux. The two satellites will be held into their orbits by centripetal force resulting from their revolution around the earth. However, the satellites will be placed in a height such they remain at the same position relative to the ground. Read More

...?Physical Science Research Paper Science is defined as “The collective findings of humans about nature, and a process of gathering and organizing knowledge about nature” (Hewitt, Suchocki and Hewitt G-12). Many things are found in nature. Living creatures, like animals and plants, are plentiful specimens to be found in nature. Nonliving things can also be found in nature. Water and earth, for example, are nonliving things which can be readily found in almost all parts of the natural environment. The physical sciences have been created for the specific purpose of gathering and organizing knowledge about the nonliving natural world (Hewitt, Suchocki and...

...? Physical Science There are various ways through which energy transits from one form to the other. One of these ways is absorption or emission of proton light by an atom. Three possible processes may produce a transformation in this case. The first process is the photochemical effect. Through this process, chemical changes within the atom facilitate the production and subsequent storage of energy. The second process is the photo electric effect that utilizes conduction electrons to transform kinetic energy into electric energy. Finally, the photo thermal effect is where the photons absorbed transform to heat energy (phonons) through vibration of molecules. Energy can also transform when nuclear reactions...

...of the wind’s kinetic energy to mechanical energy which sustains small to large farms and villages with clean and renewable loads of electricity (Freris, 1990). Modern technological advancements in the fields of engineering and science have revolutionized the old design in windmills with a flexible range of horizontal and vertical axes installed for efficient mode of energy capture. On the other hand, unlike the conventional method of burning fuels to produce the heat required, optimizing earth’s geothermal energy from deep within the ground is by nature sustainable and would not take additional chemical process to be transformed to a useful form. Moreover, geothermal energy is never likely to contribute to greenhouse...

... Operation of Circuit Breaker The turning on of portable heater in the room and subsequent opening of the room’s circuit breaker and the going off of the lights could be attributed to the high current passing through the heater or low resistance of the metal strip in the circuit breaker. To understand these postulations, it would be critical to understand the operation of circuit breakers which has been described by El-Sharkawi (31) as a switch which would automatically open when exposed to high current. The high current would cause a metal strip in the circuit to warm up and bend away from the circuit connection causing a break in the circuit. This situation could be reversed and normal operation restored after diagnosing... Operation of...

...Physical science Question Outline for testing hypothesis Fast foods, such as French fries, are believed to have such effects as increased levels of body calories and increased body weight. It is therefore important to ascertain this correlation with focus on frequency of consumption and this study investigates the relationship between twice per week consumption and three times per week consumption with focus on 16 year olds. The following hypothesis is tested. Sixteen-year-olds who eat French fries three times a week will gain more weight than those who eat French fries only twice a week. Weekly frequency consumption of French fries is the independent variables in the study. This is because the...

... Elements of Scientific Method There scientific methods are regarded as set of techniques that are usually used by the scientific communities towards investigating natural phenomena. These methods are usually applied only after setting by an objective framework for scientific investigation or inquiry. After the inquiry, a set of data is usually obtained and the same is usually analyzed towards drawing conclusion of the inquiry under investigation (Murty 35). It should be noted that the main goals or aim of the scientific methods are to obtain results that presents the physical processes within a phenomenon accurately. Notably, the conclusion of scientific trails usually emphasizes on a given number of trials so that the findings... Elements...

Euthanasia is the process where one decides to kill himself/herself to avoid the pain, agony and sufferings they undergo when ill (Jackson, 2012). It was during the era of Terri Shiva when euthanasia came to spotlight. Her husband appealed for euthanasia while Terri family had different allegations. Euthanasia has been legalized in some countries such as Belgium, Switzerland and Netherlands. Pro Euthanasia Arguments Adopting of euthanasia laws will help to reduce suffering of terminally ill patients. It will for sure be injustice and inhuman to make them endure the suffering in globe.

... Arguments and Counterarguments on Lawn Maintenance Introduction Lawn maintenance can be tedious and costly, however, if the maintenance process is coordinated and scheduled as per the lawn maintenance variables, then lawn maintenance becomes manageable. There are various arguments about lawn maintenance; some of the misconceptions relate to watering expenses, whereas others relate to the maintenance process. Most of this arguments are myths, while xeriscaping might seem like a cheaper alternative when it comes to watering and maintenance, lawns are more attractive and easier to set up. Analysis The first argument is based on prejudice and stereotypes; “lawn maintenance schedules are inconvenient.” This is a misconception because... Arguments ...

... decrease in temperatures. The thermal energy shift is what makes the metal feel cold due to a faster loss of the heat energy. You touch a wooden handle on your door and it does not feel as cold as a metal handle would. Wood is a poor conductor of heat with a low heat capacity. When a wooden surface is touched it withdraws little amounts of heat from the person touching it and as such feels warm. Works Cited Solomon, Susan, ed.
