Full explanation on Newton first law of motion |
| Answer» Newton\'s First law of motion states that there is force acting on every body which opposes its state of motion or rest . Which is also known as law of inertia . For example .. when we are sitting in bus and suddenly bus starts then our body automatically moves backward due to inertia because initially our body was in rest but when bus starts to move our body suddenly come in motion and inertia acts over there . There are three types of inertia : ● Inertia of rest ● inertia of motion ● inertia of direction | |

Define Extra polatin |
|
Answer» In mathematics, extrapolation or extra polatin is the process of estimating, beyond the original observation range, the value of a variable on the basis of its relationship with another variable. It is similar to interpolation, which produces estimates between known observations, but extrapolation is subject to greater uncertainty and a higher risk of producing meaningless results Okkkk ... I got it ... you are asking about extra polat .. we can say ... This question is from which subject ??? OK.. bro.. thanks It is used in graphs , by the way No worries sister.. bhai iska nhi pta.. if you know then mujhe bhe bata Dena.. ? |
