A bottlenose dolphin lives in warm water near the equator and a beluga whale lives in cold water near the Arctic circle. Both animals use echolocation to communicate and hunt for prey. Based on what you know about sound, which animal would be able to use its echolocation better to gather information about its surroundings?

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
