It would be "Researchers found environmental safe replacements for CFC's"
Pounds I believe? if not then I recommend google :)
Answer:
(A)-1.96e-10 nanoFarads (B)- 0.03528 C (C)- The flow of electricity is the flow of electrons through a medium. The air has to partially ionize in order to allow for the flow of electrons.Explanation:
(A) Capacitance can be calculated using or . This results in a value of 1.96e-12 nanofarads
(B) The total charge can be calculated using the equation C*V=Q
We have to find the voltage across the capacitor. To do this use the equation E*D=V. This results in a value of 1.8e8 Volts. Plug this value and the capacitance value into the equation C*V=Q. This will result in a value of 0.03528 coulombs of charge.
(C) The flow of electricity is the flow of electrons through a medium. The air has to partially ionize in order to allow for the flow of electrons.
