RMS velocity ofO3molecules = √3RTM=√3RT48 Most probable velocity ofO2molecules = √2RTM=√2RT32 Ratio of the velocities=√348:√232=1:1 Show More | ShareSave Class 11CHEMISTRYSTATES OF MATTER Similar Questions If the value of gas constant is 82.1, give its units. ...
A more useful value is the RMS which is a calculation of the steady-wave that would give the same effect. The normal RMS relies on the sinusoidal curve being perfect but that is not always the case since there is almost always som...

The larger the tank, and the greater its height (and thus its potential velocity), the greater the water's capacity to create an impact when a valve is opened and the water (like electrons) can flow. Why measuring voltage is useful Technicians approach most troubleshooting situations knowing ...
At what temperature will the rms velocity of oxygen molecules be equal to that of hydrogen molecules at 0 degrees Celsius? Why does the temperature of the water does not change while it is boiling?. Mt. Whitney is approximately 14,505 feet above sea level (0 degrees C)....
Oil whip is related to the shaft stiffness which has an eccentric structural resonance frequency not following the rotational speed. Due to the oil flow velocity, whirl is indicated by vibrations at a sub-harmonic order component between 0.42-0.48 order of the shaft rotation. Oil whirl starts ...
The similarity may in fact be part the reason that students of electrical or mechanical engineering often find the others’ studies arcane and inscrutable; “v” means “voltage” to an electrical engineer (EE), but “velocity” to a mechanical engineer (ME), whose representations of springs ...
These motors provide either rotary or linear motion. Here is a graphical representation of a typical servo system:This type of system is a feedback system, which is used to control position, velocity, and/or acceleration. The controller contains the algorithms to close the desired loop (...
Random excitation provides a pretty good Crest Factor (the peak to RMS ratio) and Signal to Noise ratio. It is one of the best signal types to use (while averaging), for the linear approximation of a system in case of non-linearities. The required averaging will increase the test time. ...
