Question

What is the apparent weight in water of a 500-gm piece ofcopper (specific gravity)? I got the question wrong on the homework. The teacher did notexplain to us how to do it, but only gave us the answer. The answeris 4.35N, can someone please solve it for me. thanks What is the apparent weight in water of a 500-gm piece ofcopper (specific gravity)? I got the question wrong on the homework.

Explanation / Answer

What is the apparent weight in water of a 500-gm piece ofcopper (specific gravity)? I got the question wrong on the homework. The teacher did notexplain to us how to do it, but only gave us the answer. The answeris 4.35N, can someone please solve it for me. thanks
specific gravity of copper=8930kg/m3
8930=weight in air/weight in air -weight in water
so
weight in air -weight in water=0.500/8930=5.599*10-5
so weight in water=apparentweight=0.500-0.00005599=0.4999kg=499.9grams
