What is dimensions? |
| Answer» Thanks ?<br>In physics and mathematics, the dimension of a mathematical space (or object) is informally defined as the minimum number of coordinates needed to specify any point within it. ... The concept of dimension is not restricted to physical objects. Dimensions are used in predicting unknown formulae by just studying how a certain body depends on base quantities and up to which extent. It makes measurement and study of physical quantities easier. We are able to identify or observe a quantity just because of its dimensions. | |

Difference between vector and scaler quantities... |
| Answer» Scalar Quantity :- The physical quantities which have only magnitude but no direction are called scalar quantity. e. g:- mass, density, volume, time etc... Vector Quantity :- The physical quantities which have both magnitude and direction is known as vector quantity. e. g :- displacement, force ,velocity etc....<br>Scalar quantity- the physical quantities,which have a magnitude but no direction called the scalar quantity.Vector quantity- the physical quantity which possess both magnitude and direction called the vector quantity. | |

What is law of motion?? |
| Answer» Okay... Bula lo???<br>Muh se aur kese ?<br>Newton’s laws of motion imply the relationship between an object’s motion and the forces acting on it. In the first law, we come to understand that an object will not change its motion unless a force acts on it. The second law states that the force on an object is equal to its mass times its acceleration. And, finally, the third law states that for every action, there is an equal and opposite reaction.<br>Bula do... But kese bulaoge?? ? | |

What is mean by Planck\'s Constant dimensional formula of Planck\'s Constant |
| Answer» What is retardation<br>The proportionality constant which relates the energy of a photon to the frequency of its related electromagnetic wave is known as Planck’s constant.Planck′s;constant(h)= Energy(E)/ frequency(upsilon)The dimensional formula of energy = [M1L2T-2]The dimensional formula of frequency = [M0L0T-1]The dimensional formula of Planck’s constant = [M1L2T-2]/ [M0L0T-1]Therefore, the dimensional formula of Planck’s constant is [M1L2T-1] | |

What is zero vector??? |
| Answer» thanks to both ?... hello broo.. mai ekdum vdiyaaa ?... aap??? ?<br>Hlo aadu .. kesi ho aapZero vector = vector with zero magnitude Unit vector = Vector which has a direction but hasmagnitude of 1 . Example - i cap , j cap etcYe last ques ka ans jo aata hai ?<br>When the magnitude of a vector is zero, it is known as a zero vector. Zero vector\xa0has an arbitrary direction.\xa0Examples: (i) Position vector of origin is zero vector.(ii) If a particle is at rest then displacement of the particle is zero vector.\xa0(iii) Acceleration of uniform motion is zero vector. | |

Rules of absolute and relative error |
| Answer» Absolute ErrorAbsolute error is the difference between measured or inferred value and the actual value of a quantity. The absolute error is inadequate due to the fact that it does not give any details regarding the importance of the error. While measuring distances between cities kilometers apart, an error of a few centimeters is negligible and is irrelevant. Consider another case where an error of centimeters when measuring small machine parts is a very significant error. Both the errors are in the order of centimeters but the second error is more severe than the first one.Relative ErrorThe relative error is defined as the ratio of the absolute error of the measurement to the actual measurement. Using this method we can determine the magnitude of the absolute error in terms of the actual size of the measurement. If the true measurement of the object is not known, then the relative error can be found using the measured value. The relative error gives an indication of how good measurement is relative to the size of the object being measured. | |

A ball is thrown vertically upwards with a velocity of 20m/s from the top of a building |
| Answer» H = u²/(2g)H = 20²/(2×10)H = 20 mThe ball will reach 20 m high from the point of projection.It reaches 20 + 20.5 = 40.5m high from the ground.(b)t1 = 2u/gt1 = 2×20/10t1 = 4 secondsIf v is the velocity with which it hits the ground then,v = √(u² + 2aS)v = √(20² + 2×10×25)v = 30 m/sv = u + att2 = (v - u)/gt2 = (30 - 20)/10t2 = 1 secondTime taken for it to hit the ground = t1 + t2= 4 + 1= 5 secondsNote: I took g = 10m/s². | |
