Two 13-cm-diameter electrodes 0.44 cm apart form a parallel-plate capacitor. The electrodes are attached by metal wires to the terminals of a 16 V battery. After a long time, the capacitor is disconnected from the battery but is not discharged.

A, B,C. What are the charge on each electrode, the electric field strength inside the capacitor, and the potential difference between the electrodes right after the battery is disconnected? Express your answer to two significant figures and include the appropriate units.

D, E,F What are the charge on each electrode, the electric field strength inside the capacitor, and the potential difference between the electrodes after insulating handles are used to pull the electrodes away from each other until they are 0.88 cm apart? Express your answer to two significant figures and include the appropriate units.

G, H,I What are the charge on each electrode, the electric field strength inside the capacitor, and the potential difference between the electrodes after the original electrodes (not the modified electrodes of parts D-F) are expanded until they are 26 cm in diameter? Express your answer to two significant figures and include the appropriate units.

The percent efficiency of a machine can never be 100% (or greater), because in the real world some energy is always converted into a. heat b. work c. input force d. output force

An isolated conducting spherical shell carries a positive charge. part a which statement (or statements) about the electric field and the electric potential inside and outside the spherical shell is correct? which statement (or statements) about the electric field and the electric potential inside and outside the spherical shell is correct? electric potential inside the shell is constant and outside the shell is changing as 1/r2 both the electric potential and the electric field does change with r inside and outside the spherical shell electric potential inside and outside the shell is constant, but not zero electric potential inside the shell is constant and outside the shell is equal to zero electric field inside and outside the shell is constant (does not change with the position r), but is not equal to zero electric field inside and outside the shell is changing as 1/r (where r is the distance from the center of the sphere) electric field inside is equal to zero and outside the shell is constant, but not zero electric potential inside the shell is constant and outside the shell is changing as 1/r electric field inside and outside the shell is changing as 1/r2 electric field inside is equal to zero and outside the shell is changing as 1/r2 electric field inside and outside the shell is zero electric field inside is constant and outside the shell is changing as 1/r
