What is the resultant of a vector cross b vector |
| Answer» A^-> × B^-> = AB sinθ n^ where n^ is a unit vector perpendicular to both A^-> and B^->, and θ is the angle between A^-> and B^->. The resultant of cross product or vector product of two vectors is itself a vector, representing a right handed system. | |

What are co-Planar vectors |
|
Answer» Vectors parallel to the same plane, or lie on the same plane are called coplanar vectors. Vectors which lies on same plane are known as co planner vectors |
|

What is vector rule |
| Answer» Vector addition is the operation of adding two or more vectors together into a vector sum. The so-called parallelogram law gives the rule for vector addition of two or more vectors. For two vectors and , the vector sum is obtained by placing them head to tail and drawing the vector from the free tail to the free head. | |

Please explain how to find instantaneous velocity ....with example |
|
Answer» Easy way to find out instantaneous velocity is to do differentiation of dispacement witch respect to time that is:V=dx/dt Instantaneous velocity is a useful tool to determine velocity at any point or any time for a body in non uniform motion.For example, average velocity in a fixed time interval is given by, Sorry it will be dx /dt By differentiating the function of positionEg- let x = 4t^2+3t+4 then velocity = dy/dx(4t^2+3t+4) = 8t+3. And time will be most probably provided in the question. |

What is relative velocity and resultant |
|
Answer» Relative VelocityThis is the velocity of an object relative to some other object which might be stationary, moving slowly, moving with same velocity, moving with higher velocity or moving in opposite direction. I dont know |
|
| 10212. |
What is ment by relative velocity |
|
Answer» Relative velocity is defined as the rate of change relative position of one object with respect to another. Relative VelocityThis is the velocity of an object relative to some other object which might be stationary, moving slowly, moving with same velocity, moving with higher velocity or moving in opposite direction.If initial position of two objects A and B are xA (0) and xB (0), the position at time t will be,\txA (t) = xA (0) + vA t\txB (t) = xB (0) + vB t\tDisplacement from object A to B, [ xB (0) - xA (0) ] + (vB -vA)t\tVelocity of B relative to A = vBA = vB – vA\tVelocity of A relative to B = vAB = vA – vB |

Explain the.law of inertia |
|
Answer» According to this law a body at rest will remain at rest and a body in motion will remain in motion at the same speed and in the same direction unless acted upon by an external force. There are great examples of this law in sports such as starting in rowing, starting in sprinting, starting in throwing the hammer. Basically if an object is in motion, it remains in motion unless something or some external force stops it. The external force may be gravitational force, the surface of playing field or a defensive player etc. Newton ist law is called law of inersia |
|

what us impulse |
|
Answer» \xa0Impulse of a force is defined as the product of force and the time for which force is acting.\xa0 Impulse\tImpulse is defined as a force multiplied by time it acts over.\tFor example: Tennis racket strikes a ball, an impulse is applied to the ball. The racket puts a force on the ball for a short time period. |

Plz sir give me answer. What is relation between (g) and (G)? |
| Answer» Small g stands for the acceleration due to gravity by earth which is 9.8 m/s and capial G stands for Newton\'s universal gravitational constant, whereas g stands for the acceleration due to gravity at a certain point. G = 6.67300 × 10^(-11) Nm^2/kg^2. G is a constant throughout space and time. | |

Mass length |
| Answer» Linear density is the measure of a quantity of any characteristics value per unit of length. Linear mass density (titer in textile engineering, the amount of mass per unit length) & linear charge density per (the amount of electric charge per unit length) are two common example used in science and engeering. | |

Examples of intrigation |
| Answer» The integration denotes the summation of discrete data. The integral is basically calculated to find the functions which will describe the area, displacement, volume, that occurs due to a collection of small data, which cannot be measured singularly. In a broad sense, in calculus, the idea of limit is used where algebra and geometry are implemented. Limits help us study the result of points on a graph get closer to each other until their distance is almost zero. We know that there are two major types of calculus –\tDifferential Calculus\tIntegral Calculus | |
