Avacuum tube diode consists of concentric cylindrical electrodes, the negative cathode and the positive anode. because of the accumulation of charge near the cathode, the electric potential between the electrodes is not a linear function of the position, even with planar geometry, but is given by v(x)=cx4/3 where x is the distance from the cathode and c is a constant, characteristic of a particular diode and operating conditions. assume that the distance between the cathode and anode is 12.0 mm and the potential difference between electrodes is 260 v . (a) determine the value of c. c = v/m4/3 (b) obtain a formula for the electric field between the electrodes as a function of x. (use your result from part (a). use the following as necessary: x.) ex = (c) determine the force on an electron when the electron is halfway between the electrodes. f = n

explanation:

as the height from which the ruler was dropped increased, the speed of the ruler at ryan's hand increased.

so here is the information for current research:

-nrel's geothermal analysts, scientists, and engineers perform a full range of research from developing advanced methods of locating and accessing geothermal resources to exploring innovative technologies to extract and produce clean energy from the heat of the earth

and here is the information for the technology of geothermal energy:

-it's clean and sustainable

-resources of geothermal energy range from the shallow ground to hot water and hot rock found a few miles beneath the earth's surface, and down even deeper to the extremely high temperatures of molten rock called magma

-almost everywhere, the shallow ground or upper 10 feet of the earth's surface maintains a nearly constant temperature between 50° and 60°f (10° and 16°c)

-geothermal heat pumps can tap into this resource to heat and cool buildings

-a geothermal heat pump system consists of a heat pump, an air delivery system (ductwork), and a heat exchanger-a system of pipes buried in the shallow ground near the building

-in the winter, the heat pump removes heat from the heat exchanger and pumps it into the indoor air delivery system

-in the summer, the process is reversed, and the heat pump moves heat from the indoor air into the heat exchanger

-the heat removed from the indoor air during the summer can also be used to provide a free source of hot water
