X-rays of wavelength 0.13 nm fall on a microcrystalline powder sample. the sample is located 17 cm from the photographic film. the crystal structure of the sample has an atomic spacing of 0.22 nm. calculate the radii of the diffraction rings corresponding to first-and-second-order scattering. note in the figure 35-28 in the textbook that the x-ray beam is deflected through an angle 2pi. express your answer using two significant figures. enter your answers numerically separated by a comma.

Ithink the answer is d i hope it my friend message me if i’m wrong and i’ll change my answer and fix it for you

Wish i knew this to !

W= fd
where f is an applied force and d is the distance over which it is applied. when a parachuting skydiver is at constant velocity, he is experiencing "terminal velocity", the point at which his acceleration down is canceled out by air resistance. that means that the resisting force of the air is equal to his weight, but in the opposite direction. with this, we can solve for the work done by the force.
w = fd
w = (92.0)(9.81 m/s^2) (325)
w= 2.93 x 10^5 j
the value for work in this case is positive because it is pushing up on the skydiver, who has a downward force of gravity.
therefore the answer is 2.93 x 10^5 j
