Can you sit on a cloud? Nope. You can’t sit on a cloud, because there’s really nothing there. What you think of as a cloud is basically just air. It looks the way it looks because there are many, many, many tiny droplets of water suspended in the air, which refract the light and make […]
Is it OK to drink glucose daily?
Is it OK to drink glucose daily? Since glucose is used when needed, it does not have a daily dosing schedule. Call your doctor if your symptoms do not improve after using glucose. Can I drink glucose in empty stomach? This screening test involves drinking a sugary liquid, followed by a blood test an hour […]
Do electrons move in their orbitals?
Do electrons move in their orbitals? Because an electron is a quantum object with wave-like properties, it must always be vibrating at some frequency. Furthermore, an electron in a stable atomic state does not move in the sense of waving through space. The orbital electron does move in the sense of vibrating in time. Can […]
How does a catalyst decrease activation energy?
How does a catalyst decrease activation energy? A catalyst can lower the activation energy for a reaction by: orienting the reacting particles in such a way that successful collisions are more likely. reacting with the reactants to form an intermediate that requires lower energy to form the product. What is difference between positive and negative […]
Is energy released in alpha decay?
Is energy released in alpha decay? The energy released in this α decay is in the MeV range, about 106 times as great as typical chemical reaction energies, consistent with many previous discussions. Most of this energy becomes kinetic energy of the α particle (or 4He nucleus), which moves away at high speed. Is energy […]
What best describes white light after it passes through a prism?
What best describes white light after it passes through a prism? Visible light, also known as white light, consists of a collection of component colors. Upon passage through the prism, the white light is separated into its component colors – red, orange, yellow, green, blue and violet. The separation of visible light into its different […]
How many volts is 2000 watts?
What four factors affect the magnitude of the induced emf in a coil?
What four factors affect the magnitude of the induced emf in a coil? What four factors affect the induced emf? The induced e.m.f. is proportional to the number of turns in a coil. The speed at which the conductor moves through the magnetic field. The length of the conductor. The rate at which the conductor […]
What is meant by a free electron?
What is meant by a free electron? 1 : an electron within a conducting substance (as a metal) but not permanently attached to any atom. 2 : an electron moving in a vacuum. Who proposed free electron model? Hendrik A. What are the types of free electron theory? Classical free electron theory of metals (Drude […]
What are the two main barriers against implementing a renewable energy system?
What are the two main barriers against implementing a renewable energy system? The Siting and Transmission However, they can still present two primary barriers to renewables namely siting and transmission. What are the barriers in implementing alternative fuels? Alternative Fuel Vehicles Are Expensive. New technologies almost always require a high level of front-end capital investment. […]
