Some of the most fundamental concepts of fluid properties are temperature, density, and composition.
I would think the answer would be c
2. The object's volume.
3. The density of the liquid.
Remember what the buoyant force is. It's the lifting force caused by the displacement of a fluid. I'm using the word fluid because it can be either a liquid or gas. For instance a helium balloon floats due to the buoyant force exceeding the mass of the balloon. So let's look at the options and see what's correct.
1. Object's mass
* This doesn't affect the buoyant force directly. It can have an effect if the object's mass is lower than the buoyant force being exerted. Think of a boat as an example. The boat is floating on the top of the water. If cargo is loaded into the boat, the boat sinks further into the water until the increased buoyant force matches the increased mass of the boat. But if the density of the object exceeds the density of the fluid, then increasing the mass of the object will not affect the buoyant force. So this is a bad choice.
2. The object's volume.
* Yes, this directly affects the buoyant force. So this is a good choice.
3. The density of the liquid.
* Yes, this directly affects the buoyant force. You can drop a piece of iron into water and it will sink. You could also drop that same piece of iron into mercury and it will float. The reason is that mercury has a much higher density than water. So this is a good choice.
4. Mass of the liquid
* No. Do not mistake mass for density. As a mental exercise, imagine the buoyant force on a small piece of metal dropped into a swimming pool. Now imagine the buoyant force on that same piece of metal dropped into a lake. In both cases, the buoyant force is the same, yet the lake has a far greater mass of water than the swimming pool. So this is a bad choice.
Answer:
Both of them.
Explanation:
They are both because when your analyzing data , that is what happen's.
We know that acceleration due to gravity is the same for all objects. But if we drop a flower petal and a hammer from the same height, the hammer falls faster. Why does this happen?
Let me try to explain. The petal falls slower as the resistance it faces by air slows it down much more. Even though the hammer is also affected by this resistance, the speed decrease is negligible due to its weight.
To simplify, a petal is much lighter than a hammer. Even though gravity accelerates them at the same speeds, the petal slows down due to air resistance but the hammer doesn't, as its weight counteracts the air resistance.
I may be confusing at times, so please ask me if you want anything clarified :)
Hope this helps you!
