Gabriella and Michelle are a few meters apart, at one end of a football field. Pierre is at the other end of the field, and he sees both of the them moving toward him 4m/s. From Michelle's point of view, how is Gabriella moving? Gabriella is moving toward her at 8m/s

Gabriella is moving away from her at 4 m/s

Gabriella is moving toward her at 4 m/s

Gabriella is not moving

force is mass*acceleration.

we have a very small mass: 11.4*0.001 kg

if we want 0.035n of force, we need an acceleration:

0.035 = 11.4*0.001*a

a = 0.035/(11.4*0.001) m/s^2

the answer is f1 and d2 because if you put equal force on those two points the beam would balance trust me on this

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
