Plz explane polygon law with the help of triangle law |
|
Answer» Consider vectors A,B,C,D and E.To find the resultant of these vectors,draw a vector ab=A,bc=B,cd=C,de=D,ef=E and af=R.Proof- join ac and apply triangle law of vector addition to ∆abcac=ab+bc = A+B.Now join ad and apply triangle law of vector addition to ∆acdad=ac+cd = A+B+C.Now join ae and apply triangle law of vector addition to ∆adeae=ad+de = A+B+C+D.Finally apply triangle law of vector addition to ∆aefaf=ae+ef = A+B+C+D+E.Therefore, R = A+B+C+D+E. Diagram is required for it but,I can\'t give u diagram but surely I can give u the solution. |

How can we derive Newtown\'s first and third law with the help of the Newtown\'s second law? |
| Answer» Newton\'s 1st law from 2nd law-According to newton\'s 2nd law F=maIf no force is applied F=0 ma=0 Since m is not equal to 0 Therefore a=0 V-U÷t=0 V-U=0 V=UIt means the body in the state of rest remains in state of rest and if the body is in uniform motion remains in uniform motion when applied force is zero. Hence the 1st law is verified.Newton\'s 3rd law from 2nd law -Suppose, two bodies having momentum P1 and P2 collide with each other. Hence from the "law of conservation of momentum " we know that- P1+P2=K (constant)Differentiating this equation with respect to \'t\'(time)-dP1÷dt + dP2÷dt = dK÷dtdP1÷dt + dP2÷dt = 0 ( since differentiation of constant term is 0) dP1÷dt = dP2÷dt F1 = -F2 (F is force)Hence, the 3rd law is verified. -by Manik Ranjan | |

Relation between parsec and astronomical unit |
| Answer» The AU or astronomical unit is the shortest distance of the three. It is the rough distance from\xa0the sun\xa0to\xa0the earth\xa0. The AU is used strictly to measure distances in our solar system.\xa0A parsec is a very complex idea. Basically it is used to measure the distances between any two objects beyond our solar system. It is complex because it takes into account the movement of the earth relative to those other two objects to better define the desired result. | |

What is coulom\'s law? |
| Answer» Coulomb\'s law states that the magnitude of the electrostatic force between two point charges is directly proportional to the product of the magnitudes of the charges and inversely proportional to the square of the distance between them.\xa0F = kQ1Q2/r2,The proportionality constant k is called the electrostatic constant and has the value: 9,0 ×109 N⋅m2⋅C−2 in free space. | |

What is diffrience b/w derive and fundamental qunatity |
|
Answer» ok its a good educatinal app meritnation is good app in comparison to other app in my opinion i also yes because.. I study from meritnation.. and I am using that app when I was in class 10th. you refer meritnation i refer that because my books are not come Fundamental quantities are those which are the most basic quantities in nature and cannot be derived. Example: Length, Mass, Time etc. You cannot derive them from other quantities. Derived quantities are those which can be derived from the fundamental quantities. Example: Seed is a derived quantity. It can be derived from fundamental quantities length and time. The units of fundamental physical quantities are called fundamental units. They are length, mass and time. These units can neither be derived from one another nor can be resolved into any other units. They are independent of one another.Units of physical quantities can be expressed in terms of fundamental units and such units are called derived units.Unit of area can be an example for derived unit. If L is the length of square then L x L = L2 is its area. Similarly, the volume of a cube is L x L x L = L3 cubic area. Units of any physical quantity can be derived from its defining equation. |
