finding rms value

AC can be defined in terms of the heat produced in a resistor due to motion of charges. The effective value (I r m s or I e f f ) of the AC is defined as the value of that direct current which produces the heat at the same rate as the alternating current in a given resistor. The..

. As the total translational kinetic energy of the molecules is K.E we see that T K. E for a given sample of a gas. Thus, the absolute temperature of a given sample of a gas is proportional to the total translational kinetic energy of its molecules. Now consider a mixture of two gases A and B. Let ..

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 ceases at absolute zero ..

Maxwell's Speed Distribution Law - The rms speed of an oxygen molecule in a sample at 300 K is about 480m/s. This does not mean that the speed of each molecule is 480 m/s. Many of the molecules have speed less than 480m/s and many have speed more than 480m/s. Maxwell derived an equation g..

. The measured values of the velocities of sound in oxygen and hydrogen are 316ms - 1 and 1284ms - 1 at NTP. This closely agrees with the predicted values. According to the kinetic theory of gases, pressure exerted by a gas is given by represents the mean square velocity of the ..

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 molecules ..

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 curre..

Which figure has the least value? => Figure 2 or Figure 4 or Figure 3 or Figure 1..

If 'f ' is a function and x is an element in the domain of f, then image f(x) of x under f is called the value of 'f ' at..

a) The value of G in the C.G.S. system is 6.67 x 10 - 8 dyne cm 2 gm - 2 . b) The value of G in the SI system is 6.67 x 10 - 1 1 Nm 2 kg - ..
