X-rays with a wavelength of 0.0711 nm create a diffraction pattern when they pass through a protein crystal. if the angular spacing between adjacent bright spots (m=0 and m=1) in the diffraction pattern is 28.9°, what is the average spacing between atoms in the crystal?

The average spacing between atoms in the crystal is .

Explanation:

Given that,

Wavelength = 0.0711 nm

Diffraction pattern = 28.9°

We need to calculate the average spacing between atoms in the crystal

Using formula of distance

Here, m = 1

Put the value into the formula

Hence, The average spacing between atoms in the crystal is .

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
