Why they are called alkali metals? Why are they called the alkali metals? The alkali metals are so named because when they react with water they form alkalies. Alkalies are hydroxide compounds of these elements, such as sodium hydroxide and potassium hydroxide. Alkalies react with acids to form salts. What is Group 4 called? Group […]

How many animals were affected by the 2011 Japan tsunami?
How many animals were affected by the 2011 Japan tsunami? The catastrophe, which killed 18,000 people and created one of the worst nuclear crises in history, also swept at least 289 Japanese species across the Pacific Ocean who hitched a ride on some of the tons of debris the tsunami sent flying. How far inland […]
What happens to error when dividing?
What happens to error when dividing? When the errors are small compared to the numbers themselves, you can work out the error in your answer by working with the relative errors (the error divided by the number itself). The relative error in the result of a division is the relative error in the numerator plus […]
How long does a tidal wave last?
How long does a tidal wave last? Large tsunamis may continue for days in some locations, reaching their peak often a couple of hours after arrival and gradually tapering off after that. The time between tsunami crests (the tsunami’s period) ranges from approximately five minutes to two hours. Dangerous tsunami currents can last for days. […]
What is the distance between two molecules?
What is the distance between two molecules? In ordered solids, the atomic spacing between two bonded atoms is generally around a few ångströms (Å), which is on the order of 10−10 meters. However, in very low density gasses (for example, in outer space) the average distance between atoms can be as large as a meter. […]

What is the final stage of erosion?
What is the final stage of erosion? At the end, a stage is reached in which the terrain has lost much of its relief and deflation hollows interfere with the drainage systems, breaking it up into local systems. During all stages sand and dust might be exported by wind to other landscapes. What are the […]
Which channel is better for stop and wait protocol?
Which channel is better for stop and wait protocol? Stop & Wait Protocol performs better for LANs than WANs because the efficiency of the protocol is inversely proportional to the distance between the sender & receiver node and as we all know that the distance is less in LANs as compared to WANs. What is […]
