A 2.0 kg mass attached to an ideal spring oscillates horizontally with an amplitude of 0.30 m. The spring N
constant is 85
m

since you're a real machine, your ama is always less than your ima, because you can never totally eliminate friction.

b.

explanation:

10.0

hypothesising or postulating

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
