How is electrical energy formed? Electrical energy is caused by moving electric charges called electrons. In power stations, turbines are turned using energy from sources such as heat, wind and moving water. Generators are machines for converting motion energy into electricity. What holds the most energy? Sorbothane® has been recognized as the highest performance, energy-absorbing […]
What is the difference between extensive and intensive economic growth?
What is the difference between extensive and intensive economic growth? Extensive growth in its pure form is based on quantitative increases in labour, capital and land, whereas intensive growth is derived from gains in overall productivity, i.e. increasing efficiency of labour and a better utilization of capital and other means of production. Which of the […]

Mind-body techniques. Biologically based practices. Manipulative and body-based therapies. Energy therapies. Which of the following is a good way to choose a primary care physician? Five tips for […]
Which two networks can be used for impedance matching?
Which two networks can be used for impedance matching? An article about how to design basic impedance matching networks using the pi and T-networks for improved selectivity. The L-network is a real workhorse impedance-matching circuit (see “Back to Basics: Impedance Matching (Part 2)” ). Is rg6 50 or 75 ohm? So a 50 Ohm cable […]
Do resistors have a positive and negative side?
Do resistors have a positive and negative side? Resistors don’t care which leg is connected to positive or negative. The + means where the positive or red probe of the volt meter is to be placed in order to get a positive reading. This is called the “positive charge” flow sign convention. Does it matter […]
What is the ratio of calcium to fluoride ions?
What will happen if all the planets line up?
What is relation between pressure and area?
What is relation between pressure and area? The relation between pressure and area is that pressure and area are inversely proportional to each other. That is when area decreases pressure exerted on that area increases. When area increases pressure exerted on that area decreases. Is pressure a kind of force? Pressure is defined as the […]
Is there another way of writing very big or small numbers?
Is there another way of writing very big or small numbers? Scientific notation is a way of writing very large or very small numbers. A number is written in scientific notation when a number between 1 and 10 is multiplied by a power of 10. For example, 650,000,000 can be written in scientific notation as […]
