Physics 33.5 Buoyancy Force (2 of 9) Fraction of Ice Cube Above the Surface

[@mixalis11111]

It's an absolute pleasure to listen to the way you carry and explain the material. What a great teacher!

[@Nidhi-ks6rn]

Best teacher online . Kudos man

[@LoraParos]

Thankyou so much sir

[@MichelvanBiezen]

You are welcome. Glad you found our videos. 🙂

[@uwanebushang9630]

Im always happy and reliefed to see your page as an option when Im looking for content.

[@MichelvanBiezen]

Thank you. We have almost every topic in physics covered.

[@NerFighterforever]

thank you you explained this better than my textbook and physics professor combined

[@tonmonna4531]

I had a question about this topic ... A cube of wood of volume 0.2m3 and the density 600kg/m3 is placed in a liquid of density 800kg/m3....... 1) what fraction of volume of the wood would be immersed in the liquid 2) what force must be applied to the cube so that the top surface can be on the same level

[@MichelvanBiezen]

That is exactly explained in this video and video # 3 in this playlist.

I have a question and hopefully you can answer it even though this video is seven years old ? Right now we have individuals for trying to convince people that if our ice caps which suddenly melt that our oceans would rise significantly ? I tried telling people they're wrong that our oceans would not rise they would remain the same because of the displacement within our oceans accounting for the ice caps that already exist , and my argument is the only thing that would increase our oceans to rise either gradually or significantly would be how big we build ships and the weight of those ships that we would be adding into our oceans , also the factor in that as China builds these artificial reefs and some of these big islands they are causing our oceans to rise and actually change the way our ocean currents are flowing which does affect our weather but that's a separate argument , but my basic question is if we had nothing in our oceans such as any ships in our icecaps would melt with the same principle apply ? I say our oceans and stay the same , so hopefully you can answer this for me ? Whether or not I am wrong ?

[@MichelvanBiezen]

If the ice covering the Arctic Ocean or the Antarctic Ocean, the sea levels would indeed not rise. However, if the ice cap on Greenland or the ice cap on the Antarctic would melt, ocean levels rise. Currently the oceans have risen about 6 inches over the last century.

[@charliesmorykin38]

@@MichelvanBiezen but also you have to take into account as we build bigger and heavier ships cargo ships and tankers along with our military especially are huge aircraft carriers compared to years ago that makes a huge difference cuz that's going to increase the ocean where is levels Rising but then you have China who's building massive Islands and that has to make a huge impact on the oceans levels? And this I feel where people are being misled by these environmental groups scaring people into believing our oceans are rising and they're going to drown eventually? LOL

[@MichelvanBiezen]

The number of ships in our oceans are too few in order to make any appreciable difference on the ocean levels.

[@charliesmorykin38]

I have to disagree with you, we have thousands and thousands of ships of all different sizes and even boats all different sizes from small boats to massive Yachts you name it if you would calculate all that Mass all that weight it definitely will make a difference to our oceans just not talking a few hundred votes I don't know if you ever took notice how big an aircraft carrier is or how big these oil tankers are or even how big some of these ships even get but if you would take each and every one of those ships which I'm talking thousands and thousands from like I said small boats tips to Yachts you name it play that Mass tell me it's not going to make a difference so I have to disagree with you plus you have to calculate on what the Chinese are doing by building these big massive islands and artificial reefs that also makes a huge difference and has an effect on our oceans and the levels

[@joebaah8660]

Thank you so very much. My mates and I have been trying to generate a solution to this for so long and you and explained it so smoothly. I understood every portion of it easily.

[@MichelvanBiezen]

Great it was helpful. Thank you for the comment.

[@mohsahra700]

Why 1 - Vl/Vo is the volume of the fraction above the surface?? how did you get it?

[@suprabhasamal1501]

Hats off to you sir ....

[@khylleiandalida3651]

Thank you so much Mr. Biezen

[@MichelvanBiezen]

My pleasure!

[@yusraal-sabahi5309]

I really love your videos sir thanks a million

[@albertopoli8896]

Good morning Sir. I can’t to understand your draw: is it a volume of water (under ) with ice (on the water)?

[@MichelvanBiezen]

It is a block of ice floating in water. And we are trying to determine the fraction of the block above the water.

[@cabdullaahishire2474]

Thanks a lot my lecturer It is important to make note before explanation.

[@martinfederico7269]

I would have just used the method in the previous video and subtract it from the total height (or invert the proportion if you are working with proportions). But that's just me.. Great video

[@dineshkumthekar3135]

Wonderfully explained, Appreciate your way of explaining and so the teaching.. Love from Pune, India

ignores density of "air" or the above fluid

Thank you very much sir 😊🙏🏻

How to find the time taken for an object to completely sink in water?

[@umeshshriyan7980]

how to calculate ice cans weight.

[@marvelz6355]

Great Video. Thanks

[@ShahFahadKhan]

Clear explanation sir, thank you

[@sarasummers8102]

sir I've a confusion about the BF. Is it the weight of the object or the "LOST" weight of the object after emerging into the liquid?

[@MichelvanBiezen]

BF = actual weight - (apparent weight when submerged)

[@saranvb]

Can you tell me why the weight of the object is equal to the weight of the displaced liquid ?

[@MichelvanBiezen]

If the object floats, then the weight of the object must be equal to the force pushing upward. That force is the buoyancy force. The buoyancy force is caused by pushing water out of the way. That force is equal to the weight of the water. See this video: Physics - Fluid Statics (8 of 10) Buoyancy Force kzbin.info/www/bejne/ql6Tmn1oat-VmdU

[@ahmedal-ebrashy3691]

Isnt it weird that weight of water is pushing against gravity?

[@MichelvanBiezen]

The air does the same. We experience buoyancy force due to being submerged in air.
