An object of density 0.8 g/cm3 is placed in a tank of liquid. The density of the liquid is 2.7 g/cm3. Find what fraction, Vdisp Vblock , of the block is submerged.

causes

fossil fuels burn

cities become more industrialized

human population grows worldwide

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
