Answer:
<h2>The advantage is that, you can add additional power devices usually using batteries.</h2>
<h2>The disadvantage is ... if one component in a series circuit fails, then all the components in the circuit fail because the circuit has been broken. </h2>
The water level that will rise is 4 cm^3
calculation
if the density i s 2.7 g/cm^3 this implies that
1cm^3 = 2.7 g
? = 10.8 g
by cross multiplication
(1 cm^3 x 10. 8 g) /2.7 g = 4 CM^3
