1. Calculate the rms speeds at 20 degrees celcius of atoms of
helium (4u)?
2. The escapte speed from the surface of the Earth is 11.2 km/s. Find at what temp. the following gas (O2) have this value as the rms speed?
3. One mole of an ideal monatomic gas is heated from 0 degrees celcius...
I took some measurements for a Physics lab and don't recall whether the Voltmeter I used reports the peak voltage or rms voltage. I need rms voltage to calculate the rms current. Can anyone tell me what the norm is for voltmeters: peak or rms?
To divide by the [squ]2 or not to divide by the...
Hello!
A 15 mW laser puts out a narrow beam 2mm in diameter. what is the average(rms) value of the magnetic field?
I have the formula E^2 = E^2_0/2 but I need some additional help figuring out how to set up the problem to solve for it. Can you help, please?
Thanks!
Dx :wink:
