1. ***present all the calculations*** Part I: The density of seawater is approximately 1.027g / cm3 and the ice density 0.93g / cm3. United Nations Iceberg (iceberg), generally has a mass of 150,000 metric tons (1 metric ton = 1000kg). Calculation (a) The buoyant force exerted by the water on the "iceberg", (b) the volume of the iceberg above sea level, (c) the volume fraction above sea level. Part II: A metal bucket with a height of 0.700 m and...

1. Most will agree that a block of steel will sink when placed in water. What can you do to make it float? (Use concepts of buoyancy) 2. What would change if we used cooking oil instead a water? How would the buoyant force change? 3. Do we experience a buoyant force exerted by the atmosphere (air around us)? Why or why not?

Three objects are placed in water. Cube A (0.5 m on a side) has a mass of 2.0 kg. Cube B (1.2 m on a side) has a mass of 4.0 kg. Cube C (2.0 m on a side) has a mass of 1.0 kg. Which cubes float? Which cube experiences the greatest buoyant force? Which experiences the least buoyant force? Show your work and/or explain your reasoning. (20 pts, 10 for floating, 10 for buoyant force)

105.00 L 5.00 kg 0.00 N Fluid Oil Water Weight of 5.00 kg wood block = 49 N Step 2: Place the wood block in the water and notice that it floats. When the wood block rests on the ground, the downward gravitational force is balanced by an upward normal (“contact") force. When floating, the gravitational force is still there, but the normal (contact") force is not. The force exerted by the fluid is the buoyant force (B). When floating,...

When a 122.4kg chest is placed on the raft, the raft floats with
its top surface 20cm above the water(10 cm is under water). The
density of the water is 1077 kg/m^3
What is the mass of just the raft?
How strong it the buoyant force being exerted by the
water on the raft?
How many crates can the raft hold (including the on on
it)?

Task 4 4 Pts A ship with a weight Wo has in seawater a depth of immersion of ho and it displaces a volume of Vo. Before it enters the mouth of a river the weight of the ship is reduced by AW, which results in a decrease of the immersion to depth to h1 and the displaced volume is now V1. When the ship enters the sweet water of the river the depth of immersion is hz and the...
