Q8: A solid specimen of dielectric dielectric constant of 4.0, shown in the figure has an internal
void of thickness Imm. The specimen is Icm thick and is subjected to a voltage of 80 kV(rms).
If the void is filled with air and if the breakdown strength of air can be taken as 30
kV(pcak)/cm, find the voltage at which an internal discharge can occur.

Living cells "pump" singly ionized sodium ions, Na", from the inside of the cell to the outside to maintain a membrane potential AV membrane = Vin - Vout - 70 mV. It is called pumping because work must be done to move a positive ion from the negative inside of the cell to the positive outside, and it must go on continuously because sodium ions "leak" back through the cell wall by diffusion. a. How much work must be done to move one sodium ion from the inside of the cell to the outside? b. At rest, the human body uses energy at the rate of approxi- mately 100 W to maintain basic metabolic functions. It has been estimated that 20% of this energy is used to operate the sodium pumps of the body. Estimate-to one significant figure the number of sodium ions pumped per second.
