Ajar made of 3/16-inch-thick glass has an inside radius of 3.00 inches and a total height of 6.00 inches (including the bottom thickness of glass). the glass has a density of 165 lb/ft3. the jar is placed in water with a density of 62.5 lb/ft3.
assume the jar sits upright in the water without tipping over. how far will the empty jar sink into the water?
what is the volume of the glass shell of the jar? precision 0.00
what is the weight of the jar? precision 0.00
what is the weight of water the empty jar will displace? precision 0.00
what is the volume of water the empty jar will displace? precision 0.00
how far will the empty jar sink?
