Elastic and Inelastic Collision

We all know that Momentum means inertia in motion. It is the product of the mass and the velocity of an object (Momentum = mass x velocity). Therefore, in shorthand notation, Momentum= mv. A moving object can have a large momentum when either it mass or velocity is large or both are large. As shown … Read more

Periodic trends in the world

2nd period, going from alkali metal to noble gas. Explain why this is so. Is the trend periodic? The atomic radius decreases going from alkali metal to noble gas in the second period, as the atomic number increases. This can be explained by the increase in nuclear charge as the atomic number, the number of … Read more

Thermal power plant general layout

A Thermal Power Plant converts the heat energy of coal into electrical energy. Coal is burnt in a boiler which converts water into steam. The expansion of steam in turbine produces mechanical power which drives the alternator (generator) coupled to the turbine. Thermal Power Plants contribute maximum to the generation of Power for any country. … Read more

Thermal Conduction, Convection and Radiation

Thermal Conduction Thermal conduction is the transfer of energy arising from temperature differences between adjacent parts of a body. Thermal conductivity is recognised as the exchange of energy between molecules and electrons in the conducting medium. The rate of heat flow in a rod of any material is proportional to the cross-sectional area of the … Read more

Bluetooth Generic Attribute (GATT) Profile

The Bluetooth SIG announced Bluetooth low energy features with version 4.0 of the Bluetooth specification in 2009. It was later re-branded as Bluetooth Smart, and has just been rebranded again in 2016 (see footnote 1 above). Consequently the terms Bluetooth Smart, Bluetooth Low Energy, BLE, and now Bluetooth low energy technology are often used interchangeably. … Read more

Application of the Steady Flow Energy Equation

Introduction The equation is used to determine total energy flows in open systems. There is the assumption that mass flow is constant through the system as well as equal total energy input and output. The energies include; internal, kinetic, heat, flow, potential and work. In a plant operation, fan reliability is very critical as failures … Read more

Hydroponics Lighting Guide

HID Lights HID (High Intensity Discharge) lights are the most popular grow lights for now, mostly used by professionals. They are highly intense and provide a very high quantity of visible light per watt of electricity consumed meaning they are highly efficient. They are classified into different types based on the material used to make … Read more

Geothermal Energy Essay

The human population is currently using up its fossil fuel supplies at staggering rates. Before long we will be forced to turn somewhere else for energy. There are many possibilities such as hydroelectric energy, nuclear energy, wind energy, solar energy and geothermal energy to name a few. Each one of these choices has its pros … Read more

Sources of Energy

Have you ever thought about how we get the energy to run the things we take for granite every single day. There are many sources of energy that that are used for transportation, heat, light, and the manufacturing of goods of all kinds. The development of science and civilization is closely linked to the availability … Read more

Energy Flow Systems

Richard White’s Organic Machine, and William Cronon’s Changes in the Land, both examine environments as energy flow systems. The energy flow model was utilized by the authors to explain relationships within ecosystems. Richard White’s thesis is to examine the river as an organic machine, as an energy system that, although modified by human intervention, maintains … Read more

Plutonium: ‘Our Country’s Only Feasible Solution’

Should we begin to manufacture one of the most destructive and infamous substances on the face on the Earth once again? The engineers say yes, but the public says no. The United States stopped making this element with the ban on manufacturing nuclear weapons. But with the continuing problem with our ever diminishing energy sources, … Read more

Alternative Fuels Essay

This day in age, one of the world’s main concerns is energy. Currently, we rely on petroleum to run our cars, and household central heat, and electricity in our homes. Petroleum is not only limited, but it is also dirtying up the world’s air, and depleting the ozone layer as it is burned. Alternative fuels … Read more

Should it be called a starmill

The windmill is driven by energy from the star which we call the sun. The sun is 71% hydrogen and 27% helium. The very high temperature and pressure inside the sun cause nuclear fusion: hydrogen and helium nuclei combine and produce vast quantities of heat. Fortunately, the sun is 150,000,000 kilometres away from us, and … Read more

Thermal Energy Essay

Heat is thermal energy being transferred from one place to another, because of temperature changes. This can take place by three processes. These three processes are known as conduction, convection, and radiation. When we place two objects with different temperatures in contact with each other, the heat from the hotter object will immediately and automatically … Read more

Nuclear Power: Cons

Since the days of Franklin and his kite flying experiments, electricity has been a topic of interest for many people and nations. Nuclear power has been a great advance in the field of electrical production in the last fifty years, with it’s clean, efficient and cheap production, it has gained a large share of the … Read more

Nuclear Energy and the Environment

In our society, nuclear energy has become one of the most criticized forms of energy by the environmentalists. Thus, a look at nuclear energy and the environment and its impact on economic growth. Lewis Munford, an analyst, once wrote, “Too much energy is as fatal as too little, hence the regulation of energy input and … Read more

Geothermal Energy Report

Geothermal energy is one of the oldest sources of energy. It is simply using and reusing (reusable energy) heat from the inside of the earth. Most of the geothermal energy comes from magma, molten or partially molten rock. Which is why most geothermal resources come from regions where there are active volcanoes. Hot springs, geysers, … Read more
