Can electrons exist alone? Electrons have mass, charge, angular momentum, an intrinsic magnetic moment and helicity, but they have no known substructure. No two electrons can occupy the same space at the same time. They are part of every atom but they can exist separately on their own as well. What happens to the atoms […]
What are examples of principles?
What are examples of principles? The definition of a principle is a basic truth or the source or origin of something or someone. An example of principle is a list of values set by a group of people. How do you write a personal principle? Guiding Principles are a set of statements which expresses your […]
Which of the following best describes a difference between artificial and natural selection?
Which of the following best describes a difference between artificial and natural selection? The following statement best describes the difference between artificial and natural selection: Natural selection acts without the input of humans: artificial selection requires human input. only via natural selection, genetic drift, migration, or mutation. Which best describes the role of mutations in […]
Does all water run through water heater?
Does all water run through water heater? The cold water service line slopes away from the water heater after splitting from the main line. Instead of sending water through the heater, cold water service lines run directly to every water appliance in the home. To get to every appliance, these pipes need to run throughout […]
Why red is more energetic than yellow?
Why red is more energetic than yellow? Since, red light has lower frequency than yellow, yellow has higher momentum than red, not mass. In a way, it’s the momentum of photons which cause the radiation pressure. If the hotter an object, the brighter it glows (more energy), then why is a blue flame less visible […]

Which of the following noble gas is least Polarisable?
Which of the following noble gas is least Polarisable? Helium Why is argon a stable element? Nearly all of the argon in the Earth’s atmosphere is radiogenic argon-40, derived from the decay of potassium-40 in the Earth’s crust. The complete octet (eight electrons) in the outer atomic shell makes argon stable and resistant to bonding […]
Why is momentum not always conserved?
Why is momentum not always conserved? The total momentum of both objects does not change. For this reason we say that the total momentum of the interacting objects is conserved. Newton’s third law implies that the total momentum of a system of interacting objects not acted on by outside forces is conserved. Is angular momentum […]
How do you know if a spring is ideal?
What are the advantages and disadvantages of coal power?
What are the advantages and disadvantages of coal power? Coal energy is an affordable energy source because of the coal’s stable price compared to other fuel sources. Coal is easy to burn. Coal produces high energy upon combustion. Coal energy is inexpensive. Why should we not use coal? In 2012, coal accounted for 37.4% of […]
