What is energy carried by electromagnetic waves called? Electromagnetic waves are waves that consist of vibrating electric and magnetic fields. They transfer energy through matter or across space. The transfer of energy by electromagnetic waves is called electromagnetic radiation. How is energy stored in a coil? The energy stored in a magnetic field is equal […]
Which of these is a consequence of speeding less wear on brakes?
Why do electrons lose or gain electrons?
Why do electrons lose or gain electrons? Explanation: Atoms and chemical species lose or gain electrons when they react in order to gain stability. Thus, typically, metals (with nearly empty outer shells) lose electrons to non-metals, thereby forming positive ions. The number of electrons depends on their position on the Periodic table (in simple terms). […]
Who owns water in the USA?
Who owns water in the USA? Water corporations have identified United States public systems as potentially profitable. These are United Water, a subsidiary of the French company Suez Environment, American Water, and Siemens from Germany which acquired US Filter Corps from French Veolia Environment and runs it under the Siemens name. Who owns water in […]
How do you calculate percent Half Life?
How do you calculate percent Half Life? As you can see from this table, the amount of reactant left after n half-lives of a first-order reaction is (1/2)n times the initial concentration….Half-Lives and Radioactive Decay Kinetics. Number of Half-Lives Percentage of Reactant Remaining 1 100%2=50% 12(100%)=50% 2 50%2=25% 12(12)(100%)=25% 3 25%2=12.5% 12(12)(12)(100%)=12.5% n 100%2n (12)n(100%)=(12)n% […]
What does the body use first for energy?
What does the body use first for energy? Carbohydrates are used for energy (glucose). Fats are used for energy after they are broken into fatty acids. Protein can also be used for energy, but the first job is to help with making hormones, muscle, and other proteins. Broken down into glucose, used to supply energy […]
What is the main building block of life?
What is the main building block of life? Carbon is the universal building block for life as we know it. Its ability to form complex, stable molecules with itself and other elements, particularly hydrogen, oxygen, and nitrogen is unique. Organic chemistry involves mil- lions of compounds. What is the function of protein? Proteins are large, […]
How is energy transferred in a bicycle?
How is energy transferred in a bicycle? Mechanical energy usually means the sum of the kinetic energy and potential energy. So when you ride your bike you hope that the muscular (chemical) energy is converted mainly into mechanical energy. Unfortunately friction will produce heat and sound and will reduce the amount of mechanical energy that […]
What is an example of semiotics?
What is an example of semiotics? Common examples of semiotics include traffic signs, emojis, and emoticons used in electronic communication, and logos and brands used by international corporations to sell us things—”brand loyalty,” they call it. What is Semiotics signification? Signifier: any material thing that signifies, e.g., words on a page, a facial expression, an […]
Why do electrons move in magnetic field?
Why do electrons move in magnetic field? Cyclonic movements Free-electron Landau states are a form of quantized state adopted by electrons moving through a magnetic field. All charged particles interact with electromagnetic fields via the Lorentz force. This interaction causes electrons in a magnetic field to move in a corkscrew pattern. Are electrons attracted to […]
