Part D The average heart rate for a teen doing moderate-intensity physical activity is about 103-144 bpm. For high-intensity activity, it is 144-175 bpm.
How do your numbers compare to the average teen? Was circuit training a moderate-or a high-intensity activity for you?

i think the answer is a, hope this : )

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
