Whose atomic theory explains how atoms emit (release) and absorb light

work: w = fd (given)

work done by chet   =50*1 = 50 j

work done by mika =40*2 = 80 j

work done by sara =30*1.5 = 45 j

work done by bill =60*0.5 = 30 j

students in order from the greatest amount of work done to the least is mika> chet> sara> bill

hence option (b) is correct.

no. dot product   =0 when vecs at right angles

amplitude

hope this

snell's law

refractve index = sin incidence / sin refraction
