1. A mass is hung on a scale and while hanging the mass is submerged in water. The scale read .45 kg when submerged. When the mass is submerged the water displaced is 100 cm^3. What is the magnitude of the mass?
2. A car with windows closed floats in water when 50% submerged. If 1 m^3 of water seeps into the car it becomes totally submerged. What is the mass of the car?© BrainMass Inc. brainmass.com October 9, 2019, 10:39 pm ad1c9bdddf
1. 0.45 Kg = 450 g
Weight in water(apparent weight) = actual weight - weight of water displaced(loss in weight)
450 g = M - 100 g ... ( 100 cm^3 of water weighs 100g )
M = 450 + 100
= 550 g
= 0.55 Kg
The mass is 0.55 Kg.
2. Floating bodies ...
The mass of an object submerged in water is determined.
