What is the rms speed of nitrogen molecules contained in an 8.2 cubic meters volume at 2.4 atm if the total amount of nitrogen is 1200 mol ? What is the rms speed of nitrogen molecules contained in a 9.1 m3 volume at 2.9 atm if ...
At what temperature is the rms speed of helium molecules half its value at STP (0C, 1.0 atm)? Root-mean-square speed of a gas molecule According to kinetic-molecular theory, the root-mean-square (rms) speed vrms of the gas molecules at absolute temperature...
rms = (3kT/m)1/2 mass of molecule = mass of mole/NA Then, mass of helium molecule is 6.6x10-26kg The Attempt at a Solution Question: Is rms speed of a helium molecule the same as the rms speed of an atom. Yes, because the atoms make up the molecule? No, helium is...
The need for true-RMS meters has grown as the possibility of non-sinusoidal waves in circuits has greatly increased in recent years. Some examples include variable speed motor drives, electronic ballasts, computers, HVAC, and solid-state environments.
( c) What is the rms speed of oxygen molecules at this temperature ? View Solution The deviations from ideal gas behaviour PV=RT were successfully explained by van der Waals he pointed out that it is not advisable to neglect the volume of molecules and attractions between themselves at all ...
At absolute zero temperature, the kinetic energy of the molecules View Solution At what temperature will the R.M.S. velocity for H2 molecule-be same as that for O2 molecule at 127° C? View Solution At what temperature is the rms speed of H2 molecules the same as that of oxygen molecu...

Dual tasks requiring sustained visual attention and upright stance are common, yet their impact on standing balance is not well understood. We investigated the role of visual attention in the maintenance of postural control, using the multiple-object tracking (MOT) task. Healthy young adults (n =...
what's the speed of blades of ceiling fan in miles/hour,where the RPM of the fan is 300 RPM and radius of the fan or length of blade is 1.91Feet ? i calculated the circumference of the circle,then i converted the calculated how much RPM per second,in this cas...
In the US, household electrical power is based on a single-phase, 120-volt ac power supply. Power measured at a wall outlet in a US home will yield sine waves that oscillate between ±170 volts, with thetrue-rmsvoltage measuring at 120 volts. The rate of oscillation will be 60 cycles ...
