## The need to belong theory

View Answer. Define RMS velocity. The root mean square speed of the molecules of different ideal gases maintained at the same temperature are the same.

The square root of a real number is not always a real number. It turns out that $\sqrt{-1}$ is a rather curious number, which you can read about in Imaginary Numbers . But have you ever thought about $\sqrt{i}$ ?

Calculate the root mean square velocity, vrms, of amolecule that has a molar mass, M, of 45.02 g/mol at a temperatureof 40.56 °C using the equation below. For thiscalculation the gas constant, R, is expressed as 8.314 J/(mol*K)and the molar mass, M, needs to be converted to kg/mol.vrms=3RTM. 15.

Norm 2 of a matrix in Matlab is equal to root square of sum of squares of all elements. The all norm functions do not change units( its because you apply both square and root-square). If you want compare the result with a reference velocity, it is better to use other measures like RMS (Root Mean Square). It is similar to norm but you should normalize the sum of squares before applying the root square.

So the final velocity then will be the square root take the square root of both sides here square root of all this and we are taking the positive square root because we know it's gonna be directed upwards 0 is the initial velocity plus 2 times its acceleration—3.2 meters per second squared— times the height that it reaches— 775 meters ...

Its mean speed is only 0.4 knot, and the mean maximum speed computed from all observations above 1 knot in the prevailing direction is 1.3 knots. There is no discernible seasonal fluctuation. The speed and direction of the current is easily influenced for short periods by changing winds.
