Answer:
Water displacement is usually the method most students use because if you do it correctly, it can be more accurate than measurement and calculation.
Explanation:
If the object has an abnormal shape, you might be unable to measure its physical dimensions accurately. Instead, what you can do is measure the volume which is displaced when the object is immersed in a liquid or a gas. This is a very common method for measuring volume, and when done correctly, it is highly accurate.
For example, if you want to know the volume of a piece of ginger root, you can fill a beaker or a measuring cup with a known volume of water – let's say one cup. Next, add the ginger. Make sure that it is submerged underwater. Then, measure the new volume at the water line. The new volume will always be more than the starting volume. Subtract the starting volume (one cup) from this new volume, and you will have the volume of the ginger.
All physical matter has a weight, volume, mass, and density. Physical matter has specific characteristics only in certain physical states.
Answer: C) it displaces an equal or greater amount of water then its own weight.
Explanation:
Let's begin by explaining that the bouyant force is the force the fluids exert in a submerged body or object, and is directed upwards. This is also in accordance with the Archimedes’ Principle:
<em>A body totally or partially immersed in a fluid at rest, experiences a vertical upward thrust equal to the mass weight of the body volume that is displaced.</em>
So, since <u>the density of a body is related to its buoyancy</u>, <u>a body will float on another fluid if its density is lower</u>. In the case of the ship, its volume is greater than its mass. However, this is not the only thing.
Ships are designed by the engineers to displace an amount of ocean water that is equivalent to their own mass in order to keep it afloat.
In other words: Ships displace its own weight in water.
This is accomplished by making the <u>ship less dense than ocean water and by the design of a wide U-shaped hull.</u> So, as the ship displaces its hull pushes water away, while the pressure of the ocean pushes up against the ship's hull; and this combination of forces (The weight of the ship and buoyant force) acting simultaneosly prevent the ship from sinking despite its huge mass.
