The metal niobium has a bcc crystal structure. if the angle of diffraction for the (211) set of planes occurs at 75.99°(first-order reflection) when monochromaticx-radiation having a wavelength of 0.1659 nm is used, compute (a)the interplanar spacing for this set of planes, and (b) the atomic radius for the niobium atom.

What are some important factors to consider when choosing a warm-up before your workout?

This is a form of winter precipitation. it is frozen precipitation falling as ice pellets. snowflakes melt into raindrops as they pass through a thin layer of warmer air. the raindrops then refreeze into particles of ice when they fall into a layer of sub-freezing air near the surface of the earth. this precipitation is called a) hail. b) rain. c) sleet. d) snow.

At what time would the magnitude of the velocity reach 36.00 km/hr
