An ethanol fire is extincted with carbon dioxide or solid chemicals extinguishers.
They are equal.
Those volumes are equal.
Water pressure is greatest against the bottom of a submerged object?
That completely depends on the object's volume (which you have not mentioned). The buoyant force on it is equal to the weight of an equal volume of water.
You will find that such an object will weigh its weight on land minus the weight of the water it displaceswhen submerged. It doesn't seem possible, but it is true. This kind of result is called 'counterintuitive'.
If 32 ml of water is displaced by a completely submerged object, that means the volume of the object is 32 ml as well (or 32 cc).
submerged plants is plant which completely submerged in the water with their roots in the bottom mud.
Submerged "out-of-water". That is not possible. It is either submerged or it is out of water. Even when an object is submerger or partically submerged it will not weigh less. The physical characteristics (weight) of the object cannot be changed. The object, when placed in water will displace a certain amount of water and the object will float if the weight of the displaced water is more that the weight of the object. The object will then sink if it weighted more that the weight of the water it displaces. That said, the actual weight of the object doesnt change but if a scale were attached to it while hanging in air, it would read greater that when the object is floating or submerged in water.
The weight of the water displaced by the object is subtracted from the actual weight of the object (out of water), leaving the object with a net positive weight while submerged.
Being immersed is completely or partially submerged in water. Being submerged is putting something completely underwater.
The buoyant force on any object in water is equal to the weight of the displaced water, regardless of how much of the object is submerged.
Yes! It is completely submerged in water.
