A scale reads 184 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?
1 answer:
Answer:
163 N
Explanation:
The density of copper is about 8.96. The ratio of the weight in water to the weight in air is about 1-1/ρ, so is about 0.8884.
0.8884 × 184 N ≈ 163 N
The submerged weight is about 163 N.
