how to calculate root mean square stack up

The root mean square speed is expressed by the relationship, The root mean square speed is commonly used and can be calculated from the following relations:..

The three molecular speeds are expressed as ..

We are now in a position to write the rms speed of the molecules in terms of the absolute temperatur..

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 AC is represented a..

Kinetic energy is given as R = 8.314 JK - 1 mol - 1 , T= 273 - 23 = 250 K 9. Calculate the root mean square speed of methane molecules at 2..

Summary - The mean deviation (M.D) of a statistical data is defined as the arithmetic mean of the numerical values of the deviations of the items from some average. For an individual series, For a frequency distribution, If M.D is calculated about mean, then ..

Summary - 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 =..

Standard Deviation of a statistical data is defined as the positive square root of the arithmetic mean of the squared deviations of items from their arithmetic mean of the series under consideration. The standard deviation is denoted b..

of a statistical data is defined as the positive square root of the arithmetic mean of the squared deviations of items from their arithmetic mean of the series under consideration. The standard deviation is denoted by s (sigma). The standard dev..

Root mean square speed, T = 27+ 273 = 300 K, M= 16. R= 8.314 x 10 7 erg k - 1 mol - 1 = 683.9 ms - ..
