Find the square root of 81 from the factor tree. => 27 or 81 or 9 or 3..

Moseley had done experiments on the characteristic X-rays and this led to the development of the concept of atomic number. The periodic table was made according to the atomic weight in earlier days. But some anomalies were found in such an arrangement. Moseley measured the frequencies of characteri..

In this theory, the rate constant is related to three factors Z, f and p by the equation k = Zfp b (19) where Z is the collision frequency f is the fraction of collisions having energy greater than the threshold energy and p is the fraction of the collisions that occurs with the reactant ..

Different forms of numbers Scientific notation, square roots, exponents, radicals, absolute value, factorial, logarithms Properties of numbers Estimation of solutions Sequences and series Proportionality/direct variation, exponential/fractional expressions Patterns, rela..

If a bottle of perfume is opened in one corner of a room, it spreads in the whole room by diffusion. If you drop a little ink in a beaker of water it will spread by itself in the beaker of water and the color spreads uniformly. Diffusion is the natural process of intermingling of the molecules of..

. But the above table does not tell us whether the length and time period are directly proportional or not. By plotting a graph between L and T we can come to know whether L and T are directly proportional or not. We plot a graph by taking L along x axis and T along y axis, Graph between length and..

Graham's Law of Diffusion - Gases have the tendency to spontaneously intermix and form a homogenous mixture without the help of external agency. This is due to the presence of large amount of empty space between the gas molecules that makes their movement rapid into each other. The gases move from ..

An alternating current is that which changes continuously in magnitude and periodically in direction. It can be represented by a sine curve or a cosine curve i.e., I = I o sin w t or I = I o = cos w t Here, I o is peak value of current and I is instantaneous value of current. w = 2 p /T = 2..

. The wavelengths absorbed appear as dark lines or bands on a bright background. According to Kirchhoff's law an element can absorb only those wavelengths from continuous light, which it emits at the same temperature. This law was used to study structure of the Sun when Fraunhoffer explai..
