The average human body has a density of 1,020 kg/m3, while mercury has a density of 13,600 kg/m3. Consider a 87.5 kg man floating in a bath of mercury, as shown below.   (a) What percentage of the volume of the man’s body is submerged beneath the surface of the mercury? (b) What downward force would would you need to apply to the man to completely submerge him in the mercury? Give your answer in units of Newton

Mercury is poured into a U-tube as shown in Figure a. The left arm of the tube has cross-sectional area A1 of 10.3 cm2, and the right arm has a cross-sectional area A2 of 4.70 cm2. Two hundred grams of water are then poured into the right arm as shown in Figure b.   (a) Determine the length of the water column in the right arm of the U-tube. cm(b) Given that the density of mercury is 13.6 g/cm3, what distance h does the mercury rise in the left arm? cm

A small statue in the shape of a falcon is painted black and has a weight of 24.1 N. The owner of the statue claims it is made of solid gold. When the statue is completely submerged in a container brimful of water, the weight of the water that spills over the top and into a bucket is 1.25 N. Find the density of the metal. Is the falcon solid gold?

What is the buoyant force of an object with a volume of 0.5 m3 that is fully submerged in water? The density of water is 1000 kg/m3. O 500 N O 420 N 4,900 N 9,800 N

If the human body has an average density of 971 kg/m3, what fraction of a person is submerged when floating gently in fresh water?

A geologist finds that a moon rock whose mass is 8.25 kg has an apparent mass of 6.15 kg when submerged in water. What is the density of the moon rock? Given that the density of water is 1,000 kg/m³. Include a diagram of the situation.

A geologist finds that a Moon rock whose mass is 8.58 kg has an apparent mass of 5.72 kg when submerged in water. What is the density of the rock?

When an object with a volume of 4 x 10^-3 m^3 is completely submerged in water ( p water = 1000 kg/m^3), the buoyant force acting on the object will be?
