If you answer this you are unlucky because i will be the demon haunting you

b. latent learning (the word "latent" itself means something that exists but isn't obvious, only under certain conditions! )

the components of a vector are the parts of the vectors that are to each other.

b perpendicular

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

the answer is c. the lower legs are levers, and the knees are fulcrums. the ankles hold the loads.
