Can we charge an insulator? Charge cannot flow along or through an insulator, so its electric forces remain for long periods of time. (Charge will dissipate from an insulator, given enough time.) Do conductors attract insulators? If the insulator started with positive charge on it, that means electrons are missing inside of it. The electrons […]
In what direction is the net force exerted on the moon?
In what direction is the net force exerted on the moon? We know from Newton’s second law of motion that an object experiencing a net force undergoes acceleration. In the case of the moon orbiting the Earth (or any object orbiting another object to which it is attracted by some force), the net force on […]
What are two bad things about plate tectonics?
What are two bad things about plate tectonics? Two bad things that can happen as a result of plate tectonics are: volcanoes and earthquakes. What is the implication of being near a plate boundary? If we choose to live near convergent plate boundaries, we can build buildings that can resist earthquakes, and we can evacuate […]
What type of research is a descriptive study?
What type of research is a descriptive study? Descriptive research is a type of research that describes a population, situation, or phenomenon that is being studied. It focuses on answering the how, what, when, and where questions If a research problem, rather than the why. What type of descriptive research study measures a population at […]

Does anything have 100 efficiency?
Does anything have 100 efficiency? A system can never be 100% efficient. The reason behind this is because of heat and sound energy are lost in some amount in every system. No matter they are waste or not. So a system doesn’t exist, with 100% efficiency. Is human body energy efficient? Alas, our bodies are […]
Who invented inches?
Who invented inches? The old English ynce was defined by King David I of Scotland about 1150 as the breadth of a man’s thumb at the base of the nail. To help maintain consistency of the unit, the measure was usually achieved by adding the thumb breadth of three men—one small, one medium, and one […]
What causes wave refraction?
What causes wave refraction? Refraction is the bending of a wave-front as it travels at different speeds over water of different depths. When different parts of the same wave-front travel at different speeds, the wave bends towards the slower part. The shallower the water, the slower the wave; therefore the wave bends towards the shallower […]
What is the chemical name for AlF3?
What is the chemical name for AlF3? Aluminum fluoride Where is aluminum fluoride found? Fluoroaluminate glass is found in optical fiber applications, such as fiber-optic imaging and medical applications. Aluminum fluoride is commonly used in ceramics, where it is found as the main chemical compound in glazes for finished products. Is aluminum trifluoride ionic? Al […]
