Is coal a energy? Coal is a combustible black or brownish-black sedimentary rock with a high amount of carbon and hydrocarbons. Coal is classified as a nonrenewable energy source because it takes millions of years to form. What emerging technologies will make coal safer? Low-NOx burners allow coal-fired plants to reduce nitrogen oxide emissions by […]
Are heat and temperature inversely proportional?
Are heat and temperature inversely proportional? (a) The amount of heat transferred is directly proportional to the temperature change. To double the temperature change of a mass m, you need to add twice the heat. (c) The amount of heat transferred depends on the substance and its phase. How will the difference in temperature of […]

Can you die from swimming in the Dead Sea?
Can you die from swimming in the Dead Sea? Is it possible to drown in it? Although whoever enters the water immediately floats, you should keep in mind that it is still possible to drown in the Dead Sea. This happens when swimmers get caught in strong winds, flip over and swallowing the salty water. […]
What are flood basalts associated with?
What are flood basalts associated with? Flood Basalts are high volume eruptions that flood vast areas of the Earth, covering broad regions with flat lying lava surfaces. When flood basalts are forming above continents they fill rift valleys via giant fissures that split the continent. Are flood basalts Polygenetic? A flood basalt province, built from […]
What are examples of fast chemical reactions?
What are examples of fast chemical reactions? Chemical reactions that complete in a very short time, such as less than 10 -6 seconds, they are called fast reactions. Examples: Magnesium ribbon is burnt in the flame of Bunsen burner; it quickly gets combusted with a noticeable spark. Similarly, a neutralization reaction between acids and bases […]

How do I find carrier frequency?
How do I find carrier frequency? The carrier frequency can then be calculated as 2X99/100×1/100 which approximates to 1 in 50. Thus a rough approximation of the carrier frequency can be obtained by doubling the square root of the disease incidence. For an X-linked disorder the frequency of affected males equals the frequency of the […]
