What is the law of gravitation |
|
Answer» The force of attraction between any two objects is directly proportional to product of their mases and inversely proportional to square of distance between them. Every object in this universe attract each other with the forces which is directly proportional to the product of their masses and inversely proportional to the square of their distance. Every obhect in the universe attaract each other with a force which is directly proportional to the product of their masses and inversly porportional to the square of distance between them Every object in universe attracts every other object with force which is proportional to the product of their masses and inversly proportional to the square of the distance between them. |

What is Newton s law |
|
Answer» Newton\'s Law of Motion are three physicial law that together laid the foundation for classical machines they describe the relationship between the body and forces acting upon it and its motion is response for those forceThe first law of Newton\'s areDefines the force qualitativelyThe second law of Newton\'s areOffer a quantitative measures of a force And the third and last law of Newton\'s areAssert that a single isolated force does not exist Thanks Puja Angel 1st law: every object resists a change during its motion.2nd law:the momentum of an object is defined by its product of mass and velocity.P=mv3rd law: every action has an equal and opposite reaction. |

Differnce between distance and displacement. |
|
Answer» 1. Distance is a scalar quantity1.And displacement is a vector quantity2. It is longest path covered2. It is shortest path covered The actual path covered by a body is known as distance Distance is a scalar quantity and it can naver be nagetive whereas displacement is a vector quantity and its si unit is meter and it can be nagetive The shortest path covered by a body is known as displacement The shortest distance covered by an object from its initial to final position is called as displacement.The total path length coverd by an object is known as distance. |

How we can see our face in a plain mirror |
|
Answer» Kyunki Hamare face or mirror ke beech mein 90 degree ka angle banta hai isliye Hum plane mirror Mein Apna Chehra dekh Pate Hain The key factor is a smooth surface,because rought surfaces scatter light instead of reflecting it. When photons rays of light comming from an object ( for example - your smiling face) strick the smooth of a , they bounce back of the same angle . Our eyes see these reflected photons as a mirror image. Because of reflection we can see our face in plane mirror |

How is the gravitational force of attraction between two masses depend on the distance between them? |
|
Answer» F=GM*m/r² Gravitational force depend two object masses on distance between them esmo the distance of gravitational force of attraction will be less if lesser distance then Moh gravitational force between the two object Gravitational force of attraction between two masses depend on the distance between them as more the distance the gravitation force of attraction will be less if lesser the distance then more gravitational force is in between the two objects because g=GMm/d square |

First low of motion |
|
Answer» If an object is in rest it will remain in rest and if the object is in motion it will remain in motion until and unless an external force is applied on it An object remains in a state of rest or of uniform motion unless compelled to change its state by an applied force is Newton\'s First Law Of Motion An object at rest will remain at rest and a body in motion countinue in motion wit a uniform speed until an external unbalenced force acts upon the body |

Q.1) Classify the element based on there physical state? |
| Answer» There are three states of matter – solid, liquid and gas.Solids: Matters which have fixed volume and shape are called solids. For example - stone, wood, brick, ice, sugar, salt, coal, etc.All metals are solid except mercury and gallium.Liquid: Matters which have fixed volume but indefinite shape are called liquids. For example - milk, water, petrol, kerosene, alcohol, oil, etc. Since liquid can flow, it is also called fluid.Gas: Matters which have indefinite shape and volume are called solids. For example - air, oxygen, hydrogen, nitrogen, carbon-dioxide, etc. | |
