What is the law of conservation of momentum |
|
Answer» Answer: In physics and chemistry, the LAW of CONSERVATION of momentum states that the momentum of an isolated system REMAINS CONSTANT. Momentum is therefore said to be conserved over TIME; that is, momentum is neither created nor destroyed, only transformed or transferred from one form to another |

Why does a compass needle get deflected when brought neara bar magnet? |
|
Answer» Answer: The compass needle is a small magnet. That's why when a compass needle is brought near a bar magnet, its magnetic field lines interact with that of the bar magnet. Hence, a compass needle gets deflected near the magnet bar. Explanation: Magnetic field The magnetic field is a field generated by the electric CHARGE or magnet in the motion. The magnetic field is the area around the moving electric charge or magnetic substance within which the force of magnetism operates. Using magnetic field lines, magnetic fields are described. It is a visual method used to VISUALISE the path of the magnetic field and its strength. Bar magnet A bar magnet is a rectangular piece of an object that has PERMANENT magnetic properties, composed of iron, steel or some other ferromagnetic material or ferromagnetic composite. It has two poles, a north and a SOUTH pole so that the magnet aligns itself while freely SUSPENDED so that the northern pole points to the earth’s magnetic north pole. The compass needle is a small magnet. That’s why when a compass needle is brought near a bar magnet, its magnetic field lines interact with that of the bar magnet. Hence, a compass needle gets deflected near the magnet bar. |

What is conservation of momentum...exaplain briefly and derive an equation for it through diagram !! ( don't answer if you don't know the answer , don't answer if you don't know the answer completely, equation and diagram you must give ) |
|
Answer» Answer: Conservation of momentum, general law of physics ACCORDING to which the quantity called momentum that characterizes motion never changes in an isolated collection of objects; that is, the TOTAL momentum of a system remains constant Explanation: Let the bodies of mass m1 and m2 MOVE with VELOCITIES v1 and v2 respectively as shown in the diagram. From equations (3) and (4) Thus, the total momentum of the system before collision = The total momentum of the system after the collision. Thus the law of conservation of momentum is proved. |

a 2 kg plate kept sudpended in air by allowing 10 marbles hitting per sec with a speed v from the downward direction.if the mass of each marbles is 20 g then determine v |
|
Answer» The mass of plate is M = 100 g = 0.1 kg ANSWER:-The mass of bullet is m = 5 g = 0.005 kg The bullets are fired at a rate of 10 bullets per second. Let v be the speed of each bullet. After colliding with the plate, they rebound with same speed. Thus, rate of change in momentum of the bullets, that is, the FORCE exerted by bullets is 2 v × 0.005 × 10 This BALANCES the weight of the plate. 2 v × 0.005 × 10 = 0.1 × 9.8 v = 9.8 m/s |
