an fcc film is deposited on the (100) plane of a single-crystal fcc hat are the miller indices of the substrate. it is determined that the angle between the [100] directions in the film and substrate is 63.4°. w plane lying in the film surface?

e

explanation:

there is no change in the electric potential energy as it is in rest on both conditions.

wavelength divides in half and speed stays the same.

electrical potential energy =0.072 j

explanation:

electrical potential energy is given by

u= q δv

q= charge=6 c

δv= potential difference and is given by

δv= e d

e= electric field

d= distance=5 mm=0.005 m

δv=2.4 (0.005)=0.012 v

now electric potential energy= u= q δv

u=6 (0.012)

u=0.072 j
