Water has density of 1000 kg /m^3.  The volume of an object is  9m^3 .  If the object is completely submerged in water then what is the mass of water it displaces? [Hint: mass of water = density of water x volume of water]     A. 9 kg   B. 1000 kg   C. 9000kg   D. Nether. Needs more information to calculate.

First Measurement moon rock in air HHF (in kg/m^3) mass M₁ Second Measurement = TA moon rock under water ||||||| A piece of moon rock is placed on a scale, as shown, and balanced with calibrated weights. First the rock is located in air; second it is submerged in water. What is the density of the moon rock, in kg/m^3? M₁ = 32.3 kg and M₂ 14.5 kg mass M₂

Bird bones have air pockets in them to reduce their weight. This also gives them an average density significantly less than that of the bones of other animals. Suppose an ornithologist weighs a bird bone in air and in water and finds its mass is 46.0 g and its apparent mass when submerged is 3.60 g (the bone is watertight). What mass of water is displaced? mass of water displaced: kg What is the volume of the bone? volume of the bone: m3 What is its average density? average density of the bone: kg/m³ about us privacy policy terms of use contact us help careers

Bird bones have air pockets in them to reduce their weight. This also gives them an average density significantly less than that of the bones of other animals. Suppose an ornithologist weighs a bird bone in air and in water and finds its mass is 43.0 g and its apparent mass when submerged is 3.60 g (the bone is watertight). What mass of water is displaced?

A balloon is released from a tall building. The total mass of the balloon including the enclosed gas is 2.0 kg. Its volume is 5.0 m?. The density of air is 1.3 kg/m. 12. What is the average density of the balloon? A) 0.2 kg/m3 B) 0.4 kg/m3 C) 0.8 kg/m D) 1.0 kg/m E) 1.2 kg/m3 13. Will the balloon rise, fall, or remain stationary, and why? A) The balloon will fall because its density is greater than that of air. B) The balloon will remain stationary because its density is less than that of air. c) The balloon will rise because the upward buoyant force is greater than its weight. D) The balloon will fall because the upward buoyant force is less than its weight. E) The balloon will fall because the downward buoyant force is greater than the upward buoyant force.
