Now please now answer please help A person hears a sound with a frequency of 100 Hertz. How often does a crest of the sound wave enter the listener’s ear?

glen is correct.

step-by-step explanation:

glen is correct because when you multiply 4 * 2 = 8.

and 4 * 3 = 12.

answer; i believe the correct answer is (40,000 j) good luck

e/c, where e is its total energy

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
