X-ray diffraction is used to study the structure of crystallized proteins, nucleic acids, and other biological macromolecules. it was actually the technique used to study the structure of dna in the early 1950s. x-rays of wavelength 0.17 nm are to used to study the structure of a protein. one of the maxima in intensity is located at 0.8 rad from the crystal planes responsible for this maximum. part awhich wavelength of x-ray listed below would give you a maximum at the same location? a. 26nmb. 43nmc. 34nmd. 60nm

the aurora is formed when charged particles emitted from the sun during a solar flare penetrate the earth's magnetic shield and collide with atoms and molecules in our atmosphere. these collisions result in countless little bursts of light, called photons, which make up the aurora.

auroras are generated by charged solar particles hitting molecules in earth's atmosphere. this usually happens in high latitudes, because our planet’s magnetic field tends to funnel these particles toward the poles. that’s why it can be experienced in northern ohio.

earth's neighboring galaxy, the andromeda galaxy, is a distance of 2.54×107 light-years from earth. if the lifetime of a human is taken to be 70.0 years, a spaceship would need to achieve some minimum speed min to deliver a living human being to this galaxy.
