Membrane walls of living cells have surprisingly large electric fields across them due to separation of ions. what is the voltage across an 9.67-nm-thick membrane if the electric field strength across it is 7.46 mv/m? you may assume a uniform e-field.

exposure to hazardous carcinogens and toxic substances can cause breathing problems, such as copd and various types of cancer. it also increases the risk of heart attacks and strokes and has serious (but no less unattractive) side effects, such as aging, yellow teeth, a terrible smell and damage to the vocal cords.
