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.

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.
Calculating The Electric Force Using Coulomb's Law. The strength of the electric force between any two charged objects depends on the amount of charge that each object contains and on the distance between the two charges. As the amount of charge gets bigger, the force gets bigger, and as the distance between the two charges gets larger, the force gets smaller.
