Wind turbines have been in use for many years. Wind turbines were used earlier in the 14th, 15th, 16th, 17 and 18th century to grind grains. Turbine blades were made from wood and cloth to extract as much wind energy as the blade can. Previously the designs of the turbine blades are not very impressive to attain the maximum amount of energy from wind.

Deserts cuts across the earth along the latitudes 200-350 (United Nations Environmental Programme 5). We are studying the deserts by looking at their unique factors. According to National Geographic, deserts are known to cover one-fifth of the earth’s land and are to be found on all the continents. Many people never have come across deserts in our life.
One of the major parameters that affect an earthquake’s shaking intensity is the physical parameter, which includes such things as soil types and rock types (Monroe &
In the article, the author states that China has over 81 million buildings that consume more energy than any other sector in United States. Hence, the approach of being more energy efficient by investing in the BTP is a great step
The temperatures for oil output, the exhaust, cooler in the engine, the cooler output, and the oil input decrease with time. The results recorded were used to calculate for the derived values such that torque was obtained as 72.7 N/M and ranges between 72.1 N/M - 72.7 N/M, the brake power was obtained to be in the range 40987.46667 KW - 8370.193333 KW.
The author states that Burgess fauna consists of many soft-bodied animals’ fossils as well as those with hard parts. A completely soft-bodied animal normally rot away before it is fossilized. Hard parts are crucial because they are more easily preserved; they are seen to help an organism last for a longer time to become fossilized.
The combined effects of cloud buoyancy, and precipitation increase electrical discharges that reach the ground (University of California, 2014). Therefore, global warming is going to cause more harm to the environment than previous
This is a form of an inelastic collision where the bullet comes to rest inside the block. Therefore, kinetic energy and linear momentum are lost.
Initially, the block being at rest has zero kinetic energy but has a potential energy=
You can also make it flow faster by increasing the length of pipe A to C while maintaining the length of the pipe from B into A. The fluid motion in this case is powered by gravitational force.
You must have a pipe in a U shape which allows the
A fuel cell is made up of; a cathode (positively charged), an anode (negatively charged), and an electrolyte (catalyst to speed up change) the cell fuel functions like a battery because it produces electricity which is used to run electric motors. The electricity is produced by combining hydrogen and oxygen-heat and water is also produced.
Voltage decays exponentially as the current flowing through the circuit grows exponentially to its maximum value. For series of equal time periods the inductor is charged to its maximum value of which the current value will never reach
By the end of this lab, you should be able to analyse circuit behaviour when DC or AC voltages are applied to the circuits. You are required to record all activities (observations, results and comments) in your logbook as you
In a bid to control oil in the Middle East, the powerful Nations give loans to oil-producing Countries in the Middle East in such a manner that it will be impossible for these Countries to repay these debts. US corporations such as Halliburton and Bechtel also win the contracts for building infrastructural projects in these oil-producing Countries.

Roughly 60 naturally occurring minerals are precipitated by living organisms. In living organisms, magnetite is formed through the process of biomineralization. Biomineralization began roughly 3500 million years ago and is a common phenomenon among living organisms today. Magnetite is precipitated by protists, bacteria, humans, and animals.
Signs of smoke or burning odor from the plane’s starter, long cranking periods, a starter spinning faster with no prop movement, a cracked starter mount, grinding
Environment refers to the surroundings of a living organism. It includes both biotic and abiotic factors such as other living organisms, plants, and the natural environment. In the book of Genesis, God created man and gave him the responsibility for the earth. These responsibilities involve participating in conservation measures.
The main objective of the experiment was to show that momentum is normally conserved in cases where there is no net external force that is acting on the system as well as to show that in other cases energy is conserved in different kinds of collisions. Such principles are critical in studying planetary motion, automobile collisions, and subatomic particle collisions.
As the stool is at rest, the angular momentum of the spinning wheel is not conserved since there is an external gravitational force applied due to the weight of the wheel. The wheel comes to rest again. On rotating the stool the angular momentum is conserved since the rotating stool counteracts the weight of the wheel.
The project was finally completed in 2006. This project was faced by one of the biggest controversies in China during its construction since it touched on sensitive issues ranging from aspects of population relocation, environmental damage, archeological heritage destruction to the economical benefits, clean power, and the most important: energy supply.
The plasticity exhibited by semiconductors was the subject of several research and studies. The major steps were taken towards explaining the mechanisms involved in simple and nanostructured semiconductors. Thus, various models have been developed to explain the mechanisms involved in the dislocation dynamics of semiconductors.
In fact, a huge number of candles or torches would light up a good-sized room. Smoke and residue of soot would make life difficult. Scientists and researchers were already working on inventing a more efficient solution for illuminating rooms. Sir Joseph Swan and Thomas

It is obvious that even after many years of study, the concept of a black hole, theories surrounding it, and the studies being conducted about it have a certain amount of enigma attached to it. It appears that many more studies have to be done to get more ideas about its formation, its functioning, and its possibilities.
The author states that in Kirchhoff’s Voltage Law, the algebraic sum of the voltages across any set of branches in a closed loop is zero. However, for this to be true a current direction must be assumed. As one moves across a resistor voltages drops and therefore the value of that voltage should be taken as negative.
The sine wave, a square wave and the triangular waveforms were careful displayed using NI Multisim software. The peak to peak Voltage and the peak voltages were determined from the graphs obtained, and the periodic time of the waves determined.
The horizontal displacement depicts a circular motion which in effect is described by a angular displacement of about 40 degrees. This is timed for a definite period of time.
When the length of the pendulum is measured it is a great determinant of the angular displacement in
The point at which the two curves intersect each other, at approximately 0.02, is consistent for all the data obtained. The mechanical energy was constant for all the points. The uncertainties represented by outliers are less
It is always regarded as coherent and simple, but it assumes creativity, human agency, and evolution. The constituent of the Newtonian ontology are the absolute space, matter, and time in that matter moves finally natural laws or the forces that control movement.
The changes happen over a period of many years, the recovery is slower, and thus the thought that a sixth extinction is going to happen in the near future should be taken seriously, since nobody knows
The temperature of the earth is mostly affected by changes in land use. The transformation in the use of the cover of the earth’s surface also affects the amount of energy released into the other hence several harmful effects. They change how much solar is radiated onto the land and the way that it is absorbed.
In addition, green building technology allows for material preservation during its construct, operation, renovation and even demolition. It is also called green construction or sustainable building due to
The acceleration units are the velocity over the time taken. Some of the fundamental illustrations are m/s2 and km/h. Acceleration is termed as a vector quantity. This is because it has a direction of final velocity minus the initial velocity.
It is therefore, nonetheless to talk of the acceleration magnitude as acceleration only if there is no ambiguity.
The author states that force is defined as the changer of motion. Meaning that there is a conventional tendency of an object to maintain its current position. All objects tend to resist changes in their current motion state. When the unbalanced force is absent, the object in a moving motion will maintain its motion state.
Secondly, it was believed that developed countries should take deliberate actions to mitigate on the increase of the harmful effects of greenhouse-effects. Lastly, the developed countries should support
The kinetic energy of the system before the impact is 2.427 joules while the kinetic energy of the system after the impact is 1.1621 joules. This difference means that 1.2649 joules of energy were lost. Before the impact, the potential energy on the object is converted to kinetic energy given the amount of velocity and height.
The force normally causes a stretch or compression on the object thereby causing a change in length. Naturally, the Rubber band fits this study since it is an elastic object which can stretch and compress upon the effect of a force. This experiment proves whether the characteristics of rubber bands make it a “non-hookean” or “hookean” material.
As much as there exists a linear relationship between stretch and force according to Hooke’s law, this relationship becomes nonlinear when the object has oscillated at different speeds. The speed at which the mass has oscillated factors in the kinetic energy which plays a significant role in the nonlinearity.
In the region under study, the Eurasian plate which carries Japan and its volcanoes thrust over the Philippine Sea plate. The boundary between the plates crack and fracture as the two plates slip past each other in the subduction process. This is the reason there
The tidal power requires large tidal differences for power to be produced in large quantity (Brewster, 104).
Tidal energy is the best and renewable source of electricity that does not emit any poisonous
There are mechanisms through which Hydrogen may be converted to Helium. Helium is a stable gas formed from Hydrogen fusion, such as the nuclear reactions that occur in the sun (Gratzel 6846). The spectral peak of solar energy is at the visible region of its spectrum which is between the ultraviolet rays and infrared light. This is with an intensity of 1.375 kW/m2, also known as the solar constant.
The theoretical acceleration obtained was 1.12 m/s2 while the experimental acceleration was given as 1.20 m/s2. The variation in the acceleration was caused by errors during the experiment. Since the margin error was +/- 0.1 m/s^2, indicates that the predicted acceleration and the experimental acceleration are equal.
Several other planes and boats have apparently gone missing from this section in good weather without even reporting distress messages. However, although there exist
The launcher was started with an angle of 100, horizontal distance was measured, and the procedure was repeated 4 times. The average value for the readings was obtained. The procedure was then repeated for angles 200, 300, 400, 500, 600, 700, 800, and 900. The angle with the longest distance was noted and uncertainties were calculated for distance.
