The Zero Vector and its Properties - Zero vector or null vector is a vector which has zero magnitude and an arbitrary direction. It is represented by . If a vector is multiplied by zero, the result is a zero vector. It is important to note that we c..

when T = 0, then C = 0 This leads us to the following definition of 'absolute zero of temperature'. Absolute zero of temperature may be defined as that temperature at which the rms velocities of the gas molecules become zero. In other words, all molecular motion ceas..

For a zero order reaction, the rate is independent of concentration of the reactant. For e.g., A Products Integration of the equation gives At t = 0, [A] = [A] o = constant Therefore equation becomes A plot of [A], that is concentration, versus time t, will be linear ..

Choose the largest number of zeros that a polynomial of degree 11 can have. => 22 or 11 or 10 or 121..

Maltose (C 12 H 22 O 11 ) - Maltose is made up of two a -D-glucose (in pyranose form) units held together by a (1 4) glycosidic bond. As there is a free aldehyde group at C-1 position of the second glucose molecule, maltose is known as reducing sugar. Maltose forms osazones. The enzyme th..
