Which of the following will not affect the rate of evaporation? Explanation: The rate of evaporation is depends on some factors like temperature, wind speed, surface area etc. But not on the mixed absolute heavy impurities. At what temperature does water start evaporating? 212° F How do you calculate the evaporation rate of water? I […]
What is the slowest spreading ocean?
What is the slowest spreading ocean? The Gakkel Mid-Ocean Ridge (MOR) is the slowest spreading center on the planet with full-spreading rates between 1.33 cm/yr along the Greenland end to 0.63 cm/yr along the Siberian end. What is the difference between a fast spread and a slow spread? Steep steps in the seafloor that can […]
What can charge an insulator?
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 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 […]
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 is the order of scientific inquiry?
What is the order of scientific inquiry? It usually consists of six steps: question, observation or investigation, hypothesis, experiment, analysis of data (reviewing what happened during the experiment), and conclusion. Which of the following is the correct order for the steps of scientific inquiry? The correct order of steps of scientific enquiry are observe, question, […]
How do you give good reasoning?
How do you give good reasoning? Each time you make a choice, there are consequences. A good way to improve reasoning skills is to make a point of stopping to consider those consequences on a conscious level. Use your imagination. Before making a choice in a given situation, pause to imagine a variety of possible […]
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 […]
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 […]
