A 2 lb weight stretches a spring 6 inches in equilibrium. An external force F .t / T sin 8t lb is applied to the weight, which is released from rest 2 inches below equilibrium. Find its displacement for t > 0.

which piece of furniture will have the most inertia and give the furniture movers the most difficulty in moving?  

answer

a 75kg dining table

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
