Where do we use maximum power transfer theorem? The Maximum Power Transfer theorem is used to find the load resistance for which there would be the maximum amount of power transfer from the source to the load. The maximum power transfer theorem is applied to both the DC and AC circuit. What is the difference […]

How does velocity affect speed?
How does velocity affect speed? Speed, being a scalar quantity, is the rate at which an object covers distance. The average speed is the distance (a scalar quantity) per time ratio. Velocity is the rate at which the position changes. The average velocity is the displacement or position change (a vector quantity) per time ratio. […]
What do you mean by net force?
What do you mean by net force? Net force is the vector sum of forces acting on a particle or body. The net force is a single force that replaces the effect of the original forces on the particle’s motion. It gives the particle the same acceleration as all those actual forces together as described […]

Also: cellular differentiation, fermentation, fertilisation, germination, tropism, hybridisation, metamorphosis, morphogenesis, photosynthesis, transpiration. What are the social changes that occur in adolescence? Social changes in adolescence Identity. Young […]
What are the disadvantages of helicopter?
What are the disadvantages of helicopter? Drawbacks Of Helicopters Generally, helicopters have lower top speeds than airplanes, and are more complex to fly. Helicopters are also more complex mechanically, they need more maintenance which makes them more expensive to operate and maintain than airplanes. Should I fly fixed wing or helicopter? Fixed wing is the […]
What is the disadvantages of bridge rectifier?
What is the disadvantages of bridge rectifier? The main disadvantage of a bridge rectifier is that it needs four diodes, two of which conduct in alternate half-cycles. Because of this the total voltage drop in diodes becomes double of that in case of centre-tap rectifier, losses are increased and rectification efficiency is somewhat reduced. What […]
What is the relationship between gas and pressure?
What is the relationship between gas and pressure? For a fixed mass of an ideal gas kept at a fixed temperature, pressure and volume are inversely proportional. Or Boyle’s law is a gas law, stating that the pressure and volume of a gas have an inverse relationship. If volume increases, then pressure decreases and vice […]
What are the disadvantages of bioethanol?
What are the disadvantages of bioethanol? What are the disadvantages of bioethanol? Debates surrounding food vs fuel: Some people are concerned that the popularity of biofuel is set to increase food prices across the globe. Efficiency: Biofuel fires tend not to get as hot as their wood-burning alternatives. Cost: Biofuel is often a little more […]
What triggers ammonium nitrate to explode?
What triggers ammonium nitrate to explode? Over time, the compound absorbs moisture, which can make the beads stick together into a huge rock, says Sella. When such a large quantity of compacted ammonium nitrate is exposed to intense heat — if, say, an accidental fire breaks out — it can trigger an explosion. Will ammonium […]
