What can charge an insulator? A conductor is a substance that allows charge to flow freely through its atomic structure. An insulator holds charge within its atomic structure. Objects with like charges repel each other, while those with unlike charges attract each other. What is difference between conduction and induction? In conduction, the neutral body […]
How do you tell if it is exothermic or endothermic?
How do you tell if it is exothermic or endothermic? An exothermic process releases heat, causing the temperature of the immediate surroundings to rise. An endothermic process absorbs heat and cools the surroundings.” What does it mean when entropy is negative? A negative change in entropy indicates that the disorder of an isolated system has […]

Where is productive efficiency?
Where is productive efficiency? In long-run equilibrium for perfectly competitive markets, productive efficiency occurs at the base of the average total cost curve — i.e. where marginal cost equals average total cost — for each good. What is meant by productive efficiency? Production efficiency is an economic term describing a level in which an economy […]
Why does the solution conduct electricity when the crystals dissolved in water?
Why does the solution conduct electricity when the crystals dissolved in water? When a crystal of an ionic compound dissolves in water, the ions separate. Again, the ions are free to move – so a solution of an ionic compound in water also conducts electricity. Which compound has the most ionic character? The greatest the […]
What Hz is harmful?
What Hz is harmful? The most dangerous frequency is at the median alpha-rhythm frequencies of the brain, 7 hz. This is also the resonant frequency of the body’s organs. What frequency can kill humans? 7 hz What is the death frequency? As of 2020, the CIA estimates the U.S. crude death rate will be 8.3 […]

What are the natural variables of Helmholtz free energy?
What are the natural variables of Helmholtz free energy? The natural variables are temperature, T, and volume, V . If the temperature and volume are held constant, the system will reach the equilibrium state (pressure, P, and entropy, S) with the minimum Helmholtz free energy. What are the four thermodynamic functions? Four important and useful […]
How does the Industrial Revolution affect the evolution of the peppered moth?
How does the Industrial Revolution affect the evolution of the peppered moth? After the pollution from the Industrial Revolution started affecting trees, most of the collected peppered moths were of the dark form. Click for more detail. As the trees darkened with soot, the light-colored moths were easier to see. They lived longer and passed […]
What are the pictorial depth cues?
What are the pictorial depth cues? Pictorial depth cues are any information conveyed to the observer of a two-dimensional image that gives the impression of 3-dimensional image. These are features that are designed to trick the eye and mind into adding depth and distance to the image. Why depth cueing is needed? Depth cueing aims […]
