How do we produce electricity? Most electricity is generated with steam turbines using fossil fuels, nuclear, biomass, geothermal, and solar thermal energy. Other major electricity generation technologies include gas turbines, hydro turbines, wind turbines, and solar photovoltaics. Which country is largest producer of electricity? China Which country has the best electricity? That year, Luxembourg had […]

What will happen to the distance between bright spots on the second screen if the distance between the two slits in the first screen is made smaller? What will happen to the distance between bright spots on the second screen if the distance between the two slits in the first screen is made smaller? The […]
What is the important role of variables in mathematics?
What is the important role of variables in mathematics? In mathematics, a variable is a symbol which works as a placeholder for expression or quantities that may vary or change; is often used to represent the argument of a function or an arbitrary element of a set. In addition to numbers, variables are commonly used […]
What is the symbol for average acceleration?
What is the symbol for average acceleration? Average acceleration, ¯a is defined as the rate of change of velocity, or the change in velocity per unit time. The units of acceleration are distance over time squared. A symbol with a bar over it is read as average – so a-bar is average acceleration. What is […]
Can a liquids density change?
Can a liquids density change? For liquids, temperature is an important factor that can affect a liquids density. Therefore we generally will always describe density at a given temperature for comparison purposes. In general, as liquid temperature increases, density decreases. Can a solid’s density change? This means that the density of a substance, for example […]
Can Silicon Make 6 bonds?
Can Silicon Make 6 bonds? It can “expand the octet” as it has 6 valence electrons, hence allowing the formation of 6 bonds. Can Silicon form more than 4 bonds? Silicon is also belong to carbon family and it has similar electronic configuration that means it has four valence unpaired electron those can be shared […]
What stops protein synthesis?
What stops protein synthesis? Nonsense suppression occurs when a stop (or nonsense) codon of mRNA (UAA, UAG or UGA) is decoded by the translation machinery as an amino acid, rather than eliciting termination of protein synthesis. What should I eat for protein synthesis? Whey protein, due to its leucine content, represents, on a per g […]
How many e must be removed?
How many e must be removed? Answer: removing each electron will give u 1.603*10^-19 C positive charge. So if u want +1*10^-7 C u need to remove +1*10^-7 / 1.603*10^-19 = 6.2383*10^11 electrons. What is the amount of charge possessed by 1 kg? Answer. Electrons in 1kg: 1/(9.11 * 10^-31) = 1.10 * 10^30. What […]
What is the SI unit used to measure the amount of a substance?
Is it possible to control the magnetic properties of a magnet can a magnet be turned on and off?
Is it possible to control the magnetic properties of a magnet can a magnet be turned on and off? In general there are two types of magnets : permanent and temporary (electromagnets). We can also control the intensity of magnetic power. On the other hand permanent magnet cannot be switched on and off but the […]
