Question

Does anyone have the answers to this lab? Want to make sure I can double check my answers. Anything will help. Thanks!Directions:
Intro Tab: 1. How can you use a block and the other tools on the Intro tab to determine the density of the “Oil”?
2. Determine what forces act on an object when is it in a fluid. How are the forces similar and different when the object sinks, floats immersed in the fluid, and when it is only partially submerged.
3. Give specific examples that you could use to explain what buoyancy is and how an objects weight can appear to change when in a fluid. Make sure to include situations where the object sinks, floats immersed in the fluid, and when it is only partially submerged.
Playground Tab:
4. Explain how you can use the information about the block and the fluid to determine if the block will sinks, floats immersed in the fluid, and when it is only partially submerged.
5. How can you determine the apparent mass of an object if you know the density of the object and the density of the fluid?
6. Challenge: Explain how an object that is more dense than water can be kept afloat by placing it on an object that is less dense than water

Need help! Want to double check my answers. Thanks!!

Explanation / Answer

2. Forces acts on object when it is in fluid are Bouancy (acting upwards) and gravity (acting downwars)

Sink --> Gravity > Bouancy

Floats -- > Bouancy > Gravity

Partially submerged --> Bouancy = Gravity

3. Bouancy is the force which is acting upwards and equal to the weight of the displaced liquid. In other words, more is the volume of object more is the bouancy force. For example, take a ballon when there is no air it will submerged, when there is some air then it will partially submerged and when there is sufficient air it will floats on the surface of water

4. If density of block > density of fluid --> it will sink

if density of block = density of fluid --> Partially submerged

if density of block < density of fluid --> It will floats

5. Apparent mass = (Density of object - Density of fluid ) * Volume of object

6. By increasing the volume of the object
