The African bush elephant weights over 8 tons, which is more than the weight of 4 cars! At maximum speed, it can run up to 40 km/h. How long does it take for an elephant running at top speed to go a distance of 10 kilometers?

D

Explanation:

15 mins

Explanation:

find the sum of the two horizontal vectors and the sum of the two vertical vectors

isoceles right angled triangle

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
