The primary optical element of the hubble space telescope (hst) is 3.2 m in diameter and has a focal length of 62 m. (treat it as a simple, single lens for this homework) the telescope is aimed at jupiter and the collected light is focused onto a sensitive charge coupled device (ccd) detector, similar to what is in a digital camera. each pixel in the detector is a 21 μm x 21 μm square, and the full ccd is 4096 x 4096 pixels. thus the ccd is about one square inch in size. the hst is in orbit very close to the earth (compared to other distances in the solar system).
look up the size of jupiter and the distance to jupiter when it is closest to earth. use the lens formula to determine the magnification of the image hubble takes.
how many pixels in diameter is jupiter’s image on the ccd?
given this ccd, what is the smallest feature on jupiter you would expect to be able to resolve? (another way of thinking about that question is: how large a square on the surface of jupiter does one pixel in the image represent? )
(eye piece parameters are not given for this question but it can be solved without them)

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
