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 rocks expand when there hot/warm  and contract when they are cold.

Iam on that question know can you tell me the answer i am realy strruglingasap

Answerthe energy required is 1.60 × 10⁻¹⁸ j, to three significant figures.explanationwe define electric potential as the ratio electric potential energy to the charge,    then the following gives us the potential difference,      the formula  may be on your formula sheet.the change in electric potential energy would be the energy that would needed to move it from point a to point b. solving for that, we get    using q = 8.00  × 10⁻¹⁹ c and  δv = 2.00 v, we get    the energy required is 1.60 × 10⁻¹⁸ j, to three significant figures.

Ansa new gas is observed in the form of bubbles;
