Which of the following is a valid set of four quantum numbers? (n, l, ml, ms) A. n = 2, l = 1, ml = 0, ms = +1/2 B. n = 2, l = 2, ml = +1, ms = -1/2 C. n = 1, l = 0, ml = +1, ms = +1/2 D. n = 1, l = 1, ml = 0, ms = -1/2 E. n = 2, l = 1, ml = +2, ms = +1/2

technology is the application of the knowledge gained by science.

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
