Natalie leaves a history classroom and walks 3 meters north to a drinking fountain. Then she turns and walks 10 meters south
to an art classroom. The total distance that Natalie traveled is
meters

Explanation:

Total distance travelled = 3m + 10m = 13m.

momentum of soft ball three times less than baskey ball

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
