Derivation of NEWTON\'s First law |
| Answer» It stats that an object is said to be at rest unless we would not apply any force .<br>First law of motion tells us that any body will not change its direction or state of motion until external force is applied. This law is also known as law of inertia<br>when there is no force then there will be no acceleration and when there is no acceleration there will be no force . by newtons second law we can prove it as f=ma if a =0 then f=0 and vice versa | |

"Anomalous expansion of water is blessing for living organisms in water" explain this statement. |
| Answer» The\xa0anomalous expansion of water\xa0helps preserve aquatic\xa0life\xa0during very cold weather. When temperature falls, the top layer of\xa0water\xa0in a pond contracts, becomes denser and sinks to the bottom. ... Thus even though the upper layer are frozen the\xa0water\xa0near the bottom is at 4°C and the fishes etc. can survive in it easily. | |

Explain law of inertia l |
| Answer» Law of inertia fallow first law of Newton that if a body is in rest it became rest or in motion became in motion if no external force is applied on it.<br>Laws of inertia devided into three laws<br>Laws of inertia decided into three laws. In the first law, an object will not change its motion unless a force act\'s on it. In the second law, the force an object is equal to its mass times its acceleration. In the third law, when two objects interact they apply forces to each other of equal magnitude and opposite direction. | |
