How is energy conserved in an electric motor Class 10? The faster the wire is moving, the greater this “back EMF” becomes. When the back EMF equals the source voltage, the current through the wire goes to zero (in the ideal case) and the motor can revolve no faster. What is the working principle of […]
What is full form of ch2?
What is full form of ch2? Alternative Title: ethene. Ethylene (H2C=CH2), the simplest of the organic compounds known as alkenes, which contain carbon-carbon double bonds. It is a colourless, flammable gas having a sweet taste and odour. Why is ch2cl2 called methylene chloride? It is named like methylene dichloride(Cl-CH2-Cl) because of having the -CH2- group […]
Can you use PEX for underground water line?
Can you use PEX for underground water line? In slab and underground Some plumbing contractors may be surprised to know that PEX is approved for use in underground as well as in-slab applications. What type of PEX is best for underground? Although an unbroken line of PEX would be ideal, dezincification-resistant brass PEX fittings or […]
What is a density graph?
What is a density graph? Density plots are used to observe the distribution of a variable in a dataset. It plots the graph on a continuous interval or time-period. This is also known as Kernel density plot. Density plots are a variation of Histograms. The peaks of a Density Plot help display where values are […]
What happens if you build a house without a foundation?
What happens if you build a house without a foundation? Although a building may be able to support the downward thrust of its load without a foundation, it’s the sideways motion that creates the problem. As the ground changes temperature with the seasons, it expands and contracts, causing instabilities that make the building lurch. What […]
Can photons hit each other?
Can photons hit each other? Since light itself does not have electric charge, one photon cannot directly interact with another photon. Instead, they just pass right through each other without being affected. A photon can spontaneously degenerate into a particle with mass and its antiparticle in a process known as pair production. Can you stop […]
Which fuel has the highest density?
Which fuel has the highest density? Liquid hydrocarbons (fuels such as gasoline, diesel and kerosene) are today the most dense way known to economically store and transport chemical energy at a large scale (1 kg of diesel fuel burns with the oxygen contained in ≈15 kg of air). What is density in petrol pump? As […]
What factor has the greatest influence on blood flow?
What factor has the greatest influence on blood flow? The three most important factors affecting resistance are blood viscosity, vessel length and vessel diameter and are each considered below. Blood viscosity is the thickness of fluids that affects their ability to flow. What are the four main factors that influence blood pressure? What are the […]
What is 4 2He called?
What is 4 2He called? 4/2He or the alpha particle that consists of two protons and two neutrons can be discharged from the nucleus during the disintegration of radioactive decay. What is the equation for radioactive decay? The law of radioactive decay describes the statistical behavior of a large number of nuclides, rather than individual […]
Why do objects transfer heat?
Why do objects transfer heat? All matter contains heat energy. Heat energy is the result of the movement of tiny particles called atoms, molecules or ions in solids, liquids and gases. The transfer or flow due to the difference in temperature between the two objects is called heat. How is heat different from temp? Heat […]
