A large capacitor in an air conditioner is typically connected to the potential difference provided to your house (120 V). Although capacitors like this are usually cylindrical, model this one as a parallel plate capacitor with square plates separated by 2.0 mm. If you want your capacitor to store 0.25 J of energy, what is the area of the capacitor plates?

Explanation:

Formula for energy stored in the capacitor is as follows.

               E =

or,          C =

The given data is as follows.

                  E = 0.25 J,        V = 120 V

Putting the given values into the above formula as follows.

                   C =

                       =

                       = F

Also,          C =

or,               A =

Putting the given values into the above formula as follows.

              A =

                  =

                  = 7846.82

Thus, we can conclude that area of the capacitor plates is 7846.82 .

answer: d. a cme increases the amount of energy in the solar wind

explanation:

coronal mass ejections, also called cmes, are large clouds of plasma and magnetic field that erupt from the sun. only when the cloud is aimed at earth will the cme hit earth and therefore cause impacts. high-speed solar wind streams come from areas on the sun known as coronal holes.
