State and explain the Newton's second law of motion |
|
Answer» s SECOND law of motion pertains to the behavior of objects for which all EXISTING forces are not balanced. The second law states that the acceleration of an OBJECT is dependent upon two variables - the NET forceacting upon the object and the mass of the object. The acceleration of an object depends directly upon the net FORCE acting upon the object, and inversely upon the mass of the object. As the force acting upon an object is increased, the acceleration of the object is increased. As the mass of an object is increased, the acceleration of the object is decreased |

Which mirror can form image with magnification 0.25 |
|
Answer» Since magnification is positive, this means that IMAGE is virtual. THEREFORE mirror can be CONCAVE or convex. However, since magnification < 1, image size is SMALLER than object. This can only be produced by a convex mirror since a concave mirror, if PRODUCES a virtual image, is always larger than the object. |

The value of momentum space |
|
Answer» Position SPACE (ALSO real space or coordinate space) is the set of all position vectors r in space, and has dimensions of length. A position vector defines a point in space. If the position vector of a point particle varies with TIME it will trace out a path, the trajectory of a particle. Momentum space is the set of all momentum vectors p a physical SYSTEM can have. The momentum vector of a particle corresponds to its motion, with UNITS of [mass][length][time]−1. |
