A typical cell has a membrane potential of -70 mV, meaning that the potential inside the cell is 70 mV less than the potential outside due to a layer of negative charge on the inner surface of the cell wall and a layer of positive charge on the outer surface. This effectively makes the cell wall a charged capacitor. Because a cell's diameter is much larger than the wall thickness, it is reasonable to ignore the curvature of the cell and think of it as a parallel-plate capacitor.How much energy is stored in the electric field of a 50-μm-diameter cell with a 7.0-nm-thick cell wall whose dielectric constant is 9.0? Express your answer to two significant figures and include the appropriate units.
Today's terrestrial background radiation is about 50 mrem/year, mainly due to the uranium and thorium decay chains, and potassium. The earliest evidence of life on earth was about 3.5 billion years ago.
small particles might be blown out of solar systems by the radiation pressure of sunlight. assume that the particles
A metal ball with a mass of 3.71·10-6 kg and a charge of +5.77 mC has a kinetic energy of 4.99·108 J. It is traveling directly at an infinite plane of charge with a charge distribution of +3.21 C/m2. If it is currently 1.87 m away from the plane of c..
