1 However, should there be need to buy the complete compressor, that would cost around $600 to $1,000. 2  Used and rebuilt compressors, on average, can cost $200 to $700. 3  This does not include the professional labor. 4  If the labor is included, this can bring the total up to $1,500 to $2,000. Used and rebuilt compressors, on average, can cost $200 to $700. 2  This does not include the professional labor. 3  If the labor is included, this can bring the total up to $1,500 to $2,000. 4  For example, some users on the website Clutchfans.net, claimed that their labor costs were a pinch shy of $1,800.
The electric field strength between two parallel conducting plates separated by 4.00 cm is 7.50Ã104V/m. (a) What is the potential difference between the plates? (b) The plate with the lowest potential is taken to be at zero volts.
With a little effort, you will find the field strength to be roughly 2.35 Teslas. So for hydrogen, a static magnetic field strength of 2.35T yields an NMR frequency of 100MHz. A 4.70T field will result in an NMR frequency of 200MHz. In other words, the NMR frequency is proportional to the magnetic field strength.
