- A scale reads 356 N when a piece of copper is hanging from it. What does it read( in N) when it is lowered so that the copper is submerged in water ?A partially filled bucket of water sits on a scale and it’s weight is 3.8 N. A piece of metal is suspended from a thread and completely immersed in the bucket ( but does not touch the bottom). The scale now reads 6.8 N. Find the volume of the metal.An aluminum cylinder weighs 1.07 N. When this same cylinder is completely submerged in alcohol, the volume of the displaced alcohol is 3.90 × 10−5 m3. If the cylinder is suspended from a scale while submerged in the alcohol, the scale reading is 0.743 N. What is the specific gravity of the alcohol? (The density of water is 1.00 × 103 kg/m3)
