What is the speed of tip of minutes hand of clock whose length is 7 cm? Calculate the speed of tip of minutes hand of a clock, whose length is 7cm. Here, l=r=7cm×10-2m. speed, v=st=2πrT=2×227×7×10-260×60=119×10-4=1.22×10-4m/s. How long is the minute hand on a clock whose tip? The minute hand of a clock is exactly six […]
Which compound has the lowest boiling point?
Which compound has the lowest boiling point? Helium Do more stable compounds have higher boiling points? Compounds with stronger intermolecular forces, larger masses, and less branching will have higher boiling points. Because compound III has more branching, these London dispersion forces would be weaker, resulting in a lower boiling point than compound II. Does branching […]
Which types of reaction is neutralization classified as?
Which types of reaction is neutralization classified as? A neutralization is a type of double replacement reaction. A salt is the product of an acid-base reaction and is a much broader term then common table salt as shown in the first reaction. The following are some examples of neutralization reactions to form salts. What is […]
What is the average rate of a reaction?
What is the average rate of a reaction? The average rate of reaction is an average rate, obtained by taking the change in concentration over a time period. The rate at which chemical substances react varies greatly. Usually, a reaction rate involves the change in the concentration of a substance over a given period of […]

Why is iron the heaviest element that can be produced in stars?
Why is iron the heaviest element that can be produced in stars? After the hydrogen in the star’s core is exhausted, the star can fuse helium to form progressively heavier elements, carbon and oxygen and so on, until iron and nickel are formed. Up to this point, the fusion process releases energy. The formation of […]

What is the impact of the Human Genome Project?
What is the impact of the Human Genome Project? Between 1988 and 2010 the human genome sequencing projects, associated research and industry activity—directly and indirectly—generated an economic (output) impact of $796 billion, personal income exceeding $244 billion, and 3.8 million job-years of employment. What are the two important goals of the Human Genome Project? The […]
What is the main difference between prokaryotic and eukaryotic?
What is the main difference between prokaryotic and eukaryotic? Prokaryotes are organisms that consist of a single prokaryotic cell. Eukaryotic cells are found in plants, animals, fungi, and protists. They range from 10–100 μm in diameter, and their DNA is contained within a membrane-bound nucleus. Eukaryotes are organisms containing eukaryotic cells. What are two most […]
Are radiowaves harmful?
Are radiowaves harmful? Radiofrequency (RF) radiation, which includes radio waves and microwaves, is at the low-energy end of the electromagnetic spectrum. If RF radiation is absorbed by the body in large enough amounts, it can produce heat. This can lead to burns and body tissue damage. Is UV light bad for your skin? Exposure to […]
