What happens when you double capacitance? Doubling the plate separation halves the capacitance so the stored energy reduces to 1/4. C.V^2. The stored energy is reduced by current flowing back into the battery. If the potential difference across the capacitor is doubled, how does capacitance change? Does stored energy increase with distance? Now if the […]
What is a dimensional formula?
What is a dimensional formula? Dimensional formula (equation) (Definition) : An equation, which gives the relation between fundamental units and derived units in terms of dimensions is called dimensional formula (equation). In mechanics the length, mass and time are taken as three base dimensions and are represented by letters L, M, T respectively. What unit […]
Is the Earth a positive or negative charge?
Is the Earth a positive or negative charge? Description. Atmospheric electricity is always present, and during fine weather away from thunderstorms, the air above the surface of Earth is positively charged, while the Earth’s surface charge is negative. What is the constant charge of earth? According to the charge-neutrality principle, the electric charge of the […]
What kind of energy would a textbook lose if you dropped it off of a building?
What kind of energy would a textbook lose if you dropped it off of a building? The book’s potential energy can be released by knocking it off the table. As the book falls, its potential energy is converted to kinetic energy. When the book hits the floor this kinetic energy is converted into heat and […]
Which of the following is the best definition of a physical change answers com?
Which of the following is the best definition of a physical change answers com? A physical change is when a substance undergoes a process whereby its physical features change but its chemical features stay the same. By definition, any change in the state of matter is a physical change. Which of the following is the […]
Is the entire ocean floor covered in sand?
Is the entire ocean floor covered in sand? The simple answer is that not all of the ocean floor is made of sand. The ocean floor consists of many materials, and it varies by location and depth. In shallow areas along coastlines, you’ll mainly find sand on the ocean floor. Over 70 percent of Earth’s […]
What is the purpose of flight spoilers?
What is the purpose of flight spoilers? The primary purpose of the ground spoilers is to maximise wheel brake efficiency by “spoiling” or dumping the lift generated by the wing and thus forcing the full weight of the aircraft onto the landing gear. The spoiler panels also help slow the aircraft by producing aerodynamic drag. […]
What type of fixed pitch propeller produces more RPM?
What type of fixed pitch propeller produces more RPM? The cruise propeller has a higher pitch, therefore more drag. More drag results in lower RPM and less horsepower capability, which decreases performance during takeoffs and climbs, but increases efficiency during cruising flight. What is the difference between a fixed and variable pitch propeller? For a […]
What energy system that breaks down carbohydrates using 1 to 2 minutes?
What energy system that breaks down carbohydrates using 1 to 2 minutes? glycolysis What exercises use the Phosphagen system? Sports of very short duration, with requirements for immediate energy availability are the obvious beneficiaries of the phosphagen system: shot put, high jump and sprints, or burst-like sports, such as football, basketball, and volleyball. How long […]
