How many types of indicators are there? Types of Indicators Artificial and Natural indicators are the two types of Chemical indicators. Litmus, red cabbage, turmeric, china rose are a number of the present indicators around us. What is another type of indicator? An indicator prepared from natural substances is known as natural indicator. Examples are […]
How is energy conserved in an electric motor Class 10?
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 […]
How fast does ultrasound travel through air?
How fast does ultrasound travel through air? It is important in image resolution. Figure 7. Sound waves must have a medium to pass through. The speed at which a sound wave travels through a medium is called the propagation speed or velocity….C. The Basic Process in Greater Depth. Material Velocity (m/s) air 331 fat 1450 […]
What are two examples of sustainable resources?
What are two examples of sustainable resources? Examples of Sustainable Development Wind Energy. Solar Energy. Crop Rotation. Water efficient fixtures. Green Spaces. How a city can be sustainable? This means the main ways cities can become greener are to: Reduce the amount of energy and resources used through improving the efficiency of systems, for example […]
Where is the tropical zone?
Where is the tropical zone? The tropics are regions of the Earth that lie roughly in the middle of the globe. The tropics between the latitude lines of the Tropic of Cancer and the Tropic of Capricorn. The tropics include the Equator and parts of North America, South America, Africa, Asia, and Australia. Which zones […]
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 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 […]
