Answer:
The advantage of the SI unit over CGS unit are:
- S.I has broader base. It has seven base units and two supplementary units.
- S.I is metric.
- S.I is coherent.
- S.I is rational, i.e. it gives one unit for one physical quantity .e g. for energy of any type i.e, mechanical or heat or electrical.There is only one unit Joule(J) but in M.K.S system unit for mechanical energy is joule.

Answer:
-10.0 cm
Explanation:
OK so in the equation they're having you use the variables are:
So we simply plug in the variables:
Immersed => totally submerged
a) Volume occupied by the ball, V = area of the base of the cylynder * water level rise
V =π(r^2)(4cm) = π*100cm^2*4cm = 400 π cm^3
Volume of a sphere = [4/3]π(r^3) = 400 π cm^3 =>
r^3 = 300 cm^3 => r = ∛(300 cm^3) = 6.69 cm
b) V = π(100cm)^2 (8cm) = 80,000 π cm^3
[4/3]πr^3 = 80,000π cm^3 => r^3 = 60,000 cm^3 => r = 39.15 cm
