June moves 5.0 meters south in 3.0 seconds, then continues south 3.0 meters for 3.0 seconds, and finally turns and walks an 10.0 meters north in 5.0 seconds. What is her average velocity?

the part of the wave he is travelling on is the crest

3. dark matter

empty space could also be a simple vacuum

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
