| Answer» When magnesium is added in the water a chemical reaction occurs and hydrogen gas is produced. H2 is lighter so it comes up, but the reaction soon stops as magnesium hydro oxide is formed that is insoluble in water and acts as barrier for further reaction and starts floating on the surface. | |

Distinguish between the terms\'overloading\' and short- circuiting as used in domestic circuits. |
|
Answer» The current flowing in domestic wiring at a perpendicular time depend on the power rating of a billions being used if too many electrical appliance of high power rating (like electric iron water heater air conditioner etc.)are sweet on it same time did raw egg extremely large current from the circuit this is known as overloading the circuit OVER LOADING: When too many electrical appliances of high power voltage is switched on at the same time,a large current from the circuit is drawn.This is called overloading of the circuit.SHORT CIRCUITING:When the live wire and neutral wire come into direct contact,a large amount of current flows through the circuit due to very small resistance ,this is called short circuiting. Overloading occur when more electric device on same time and shortcircuting occur when two naked wire come in contact each other |

Why the wood can catch ? easily |
|
Answer» The reactants, such as the wood in the campfire, have a certain amount of energy stored in their chemical bonds. This energy can be released when these materials react with the oxygen in the air (combustion) and are converted to the combustion products (usually carbon dioxide and water). https://www.quora.com/Why-does-wood-burn-Why-doesnt-metal-burnWhy does wood burn?

Why do two magnetic field lines of force never intersect |
|
Answer» If they intersect then the theorem taat only one tangent can be drwan fronm one point of circle become wrong If electric lines intersect, then at a single point, there would be two electric lines, that is, two directions of electric field. But, at one point, there cannot be two directions of electric field. So, electric lines cannot intersect each other. Similarly with magnetic lines. Because if they intersect each other then magnet will detect two directions at the same time which is not possible Because they are parallel |

Uses of ac and dc current |
| Answer» Alternating Current (AC): In alternating current the electric charges flow changes its direction periodically. AC is the most commonly used and most preferred electric power for household equipment office and buildings, etc. It was first tested based on the principles of Michael Faraday in 1832 using a dynamo electric generator.Alternating current can be identified in wave form called as sine wave, in other words it can be said as the curved line. These curved lines represent electric cycles and is measured per second. The measurement is read as Hertz or Hz.Direct Current: Unlike alternating current, the flow of current in direct current do not changes periodically. The current flows in a single direction in a steady voltage. The major uses of DC is to supply power for electrical devices and also to charge batteries. For example, mobile phone batteries, flashlights, flat-screen television, hybrid and electric vehicles. DC has the combination of plus and minus sign, a dotted line or a straight lines. | |

Prove that ,1/v-1/u=1/f |
| Answer» Object distance (u), image distance (v) and focal length (f) of a spherical lens are related as:1/v – 1/u = 1/f.The formula is a relation between the object distance u, image distance v and the focal length from the pole of the concave mirror. The formula is valid for the images in a convex mirror and even for the images in the lens.We consider the image formed by a concave mirror whose focal length is f and whose radius of curvature is r = 2f.Let P be the pole of the concave mirror. Let P, F , C be the pole, focal point, and centre of curvature along the principal axis. So, PC = 2PF , as r = 2f.\xa0 | |
