What is the difference between loudness and frequency?
What is the difference between loudness and frequency? Frequency (the number of vibrations or sound waves per second) is measured in Hertz (Hz). A sound that is 4,000 Hz (like the sound the letter “F” makes) has 4,000 waves per second. Intensity (loudness) is the amount of energy of a vibration, and is measured in […]
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 […]
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 […]
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 […]

What causes static electricity in a person?
What causes static electricity in a person? Static electricity is created when positive and negative charges aren’t balanced. Protons and neutrons don’t move around much, but electrons love to jump all over the place! When an object (or person) has extra electrons, it has a negative charge. Why is my laundry so static? What causes […]

A common ingredient in plastic bottles, Bisphenol A (or, BPA) is one of the most potentially dangerous things about a soft drink. A study from the American Heart Association in 2014 revealed that BPA leaching from cans could […]
