Closer to the moon than to Earth because Earth has a greater mass than the moon
This is an example of the logic fallacy called " post hoc ergo propter hoc", meaning roughly "after that, therefore caused by that". Another example: 99.99% of the people arrested for public drunkenness in the US last month had ice in their last three mixed drinks. Therefore, this is factual evidence that ice makes people drunk.
(a) When immersed in the liquid, the solid displaces an amount of liquid weighing 64 N - 48 N = 16 N, and this is the same as the magnitude of the buoyant force/upthrust.
(b) Archimedes' principle says the solid has a volume equal to that of the displaced liquid. At a density of 0.8 g/cm³ = 0.0008 kg/cm³, a 16-N amount of this liquid has a volume of
(16 N) / <em>g</em> × (1/0.0008 cm³/kg) = 2040.82 cm³
(c) Density is mass per unit volume, so you get the solid's density by dividing its mass (weight/<em>g</em>) by the volume in (b):
((64 N) / <em>g</em>) / (2040.82 cm³) ≈ 0.0032 kg/cm³ ≈ 3.2 g/cm³
Answer:
it's x that is the right answer
