Q: How many times does the height of the largest wave increase with each level? Read this paragraph and choose the correct option from the provided answers: Richter scale magnitudes jump from one level to the next. The height of the largest wave increases 10 times with each level. So the height of the largest seismic wave of a magnitude 5 quake is 10 times that of a magnitude 4 quake. A magnitude 5 is 100 times that of a magnitude 3 quake. With each level, thirty times more energy is released. A difference of two levels on the Richter scale equals 900 times more released energy. Choices: - 20 times - 100 times - 5 times - 10 times A:
10 times

Q: What are composed of an oxygen atom that forms single bonds with two carbon atoms? Read this paragraph and choose the correct option from the provided answers: Ethers are composed of an oxygen atom that forms single bonds with two carbon atoms. Ethers are relatively unreactive making them good solvents for other organic compounds, such as in the formation of anesthetics. Choices: - sugars - solvents - acids - ethers A:
