@@MichelvanBiezen sir i have question.what is the actual definition of frequency a) cycle completed per unit time or b) full cycle completed per unit time.If a waves moves 3.5 cycle in 1 sec then what is it's frequency.
Thank you very much. I really liked this one. so if I want to calculate the average density of a composite part, I can do this test , by knowing its mass and the amount of volume of liquid displaced I can easily find out the average density. By the way what if the object is so dense that it doesn't experience buoyancy and it falls to the bottom of the liquid chamber?

To find the density of an object we use the mass (not the weight). Density is defined as the mass / volume. To find the weight you multiply the mass by g (the acceleration due to gravity).
On the left side, the tension on the string equals the weight of the block. On the right side the tension on the string equals the weight of the block minus the buoyancy force.
Hello Mr. van Viezen, let me make you a very single question. In the last part of this video, which I´ve followed with huge interest (not only this but the complete of 10), the answer is a volume. Up to this moment I always understood that the units for volume was cubic units but here we have kg/m3 which is units of a density. So I´m a little bit disagreement. It seems to be that I´m completely wrong but I hope you can solve my doubts. Once aganin thank you for your dedication.
Note that the units for the buoyancy force is in Newtons (since it is a force). Thus you may need to calculate the weight of the object and the weight when submerged (in Newtons) in order to find the buoyancy force.
I paused the video to attempt the problem on my own and almost had a panic attack when his final answer had Volume with kg/m^3 as units. Glad he fixed it though XD
Sir, may I ask how did you come up with the units? Example in finding the volume, how did you cancel the kg there? Waiting for your response sir, Thankyou
How about on the last part sir, the unit of gravity is m/s² and the unit of volume is m³ then how come the unit of density becomes kg/m³? How did you cancel the m unit in gravity?
sir if an ornament weighs 36 kg in air and 34kg in water and we are told that some copper is mixed with gold to prepare it then how can I find how much copper was mixed (SG of cu-19.3,of gold 8.9).I know that the BF will be 2N but how to proceed in the problem ????
sir I made a small mistake that the object's mass is 36gm and not kg in air and 34gm in water and after that I calculated its density which I got to be 18×10^3kg/cubic metre.What will be the next step ???
If you know the density and the weight in air: density = mass / volume, you can find the object's volume. Then you can find the buoyancy force = (density of fluid) (volume of object) (g) Then you find the weight in water = weight in air - buoyancy force.
Hi. Great vid and channel. You cover a lot of areas, including a few that I've been struggling with lately. I sent you a message about the archimedes principle. Could you let me know if you received it please? I can't see anything on my youtube profile that lets me view outgoing or incoming messages.
It is a matter of "significant" figures. (See the playlist on significant figures). In the calculation leading up to the final answer the buoyancy force was 8 N which only has one significant figure, so technically our answer should only have one significant figure.

Wow I just realzied this comment existed, I graduated a year ago and I watched your videos a lot throughout school, they helped a ton, thank you!
I feel like this guy should write his own textbook because he explains in a good manner
There are already so many text books out there. It would be hard to compete. That is why we decided to make these videos.

Glad you found our videos and you found them helpful! 🙂
Thank you! You make these topics so easy and clear.
IM GOING TO FAIL PRAY FOR ME PLEASE 💔
This is literally one of few physics videos that actually explain the concept right.
His accent keeps me entertained.
Wowow by nearly 6 minutes I get it ,thanks 💐💐
Most welcome 😊 Glad you found the video helpful.

All objects, regardless of their density, once submerged will experience a buoyancy force.
Crystal clear ! Maybe formula of the density of interest could be reduced into single form.
Thank you
how did you come up with 5000 sir? 40/9.8 then divided by 8.16x10^-4.. my scical says different :(
I get 5002 which is rounded to 5000. You sure you are typing the numbers correctly?
Brightness to be increased..
Yes our older videos do not have enough lighting.
sir,thank you for giving awesome videos so i can learn physics by myself!!!
U still learning physics bro?
I am learning Physics as well :D

Very well explained
Sir, I would just like to ask a question, why do you not use the weight of the object submerged in the water in calculating the density (p=m/v)?
To find the density of an object we use the mass (not the weight). Density is defined as the mass / volume. To find the weight you multiply the mass by g (the acceleration due to gravity).
sir, can you explain on how the string that tie the block to the Newton's balance affffect the experimental results using Archimedes principle
On the left side, the tension on the string equals the weight of the block. On the right side the tension on the string equals the weight of the block minus the buoyancy force.
I think in the end you meant density = 5000kg/m^3 and not volume
You are correct
ITS MENTIONED
@@irfanahmad2845 He edited that in lol you can see the cut scene right before he says 'Oh!'. - took me second look as well.
Why did you substract the weights in air and water?
To find the buoyancy force. BF = weight in air - weight in water
Awesome sir

If you watch the video all the way to the end, you'll see that I caught the error, and corrected the symbol from V to density.
Hi sir, why do we use 40 N and not 32 N in the last part??
At the end we want to calculate the density of the object = m/V (It has to be the mass of the object)
edit: I love your correction part of the video!
Hello, can I ask? What if the given weights are in grams? Do we have to convert it to newtons first before solving the volume?
Note that the units for the buoyancy force is in Newtons (since it is a force). Thus you may need to calculate the weight of the object and the weight when submerged (in Newtons) in order to find the buoyancy force.
@@MichelvanBiezenooohh, okay. thank you very much, sir. 😊
how did the 5000 come from sir? 40 divided by 9.8 then divided again by the volume? my scical got diff answer :(
Thank you sir, it really helped me a lot !
Thankyou sir

Sir, may I ask how did you come up with the units? Example in finding the volume, how did you cancel the kg there? Waiting for your response sir, Thankyou
Remember that 1 N = 1 kg m/sec^2 Hope that helps.
How about on the last part sir, the unit of gravity is m/s² and the unit of volume is m³ then how come the unit of density becomes kg/m³? How did you cancel the m unit in gravity?
We're taking m only cuz density is m over v . So unit of mass is kg
w/g is just for finding the mass
thank U for your best lecture
dose this work if we have tension
sir question on mata centric height
thank you so much for this!
Thank you so much
sir if an ornament weighs 36 kg in air and 34kg in water and we are told that some copper is mixed with gold to prepare it then how can I find how much copper was mixed (SG of cu-19.3,of gold 8.9).I know that the BF will be 2N but how to proceed in the problem ????
+Rahul Tiwari
BF = ( 2 * 9.8 )N
FInd the density first.
sir I made a small mistake that the object's mass is 36gm and not kg in air and 34gm in water and after that I calculated its density which I got to be 18×10^3kg/cubic metre.What will be the next step ???
RAHUL, your question is not clear, make it clear to yourself first. w=36g and D=18X10^3kg???????
You are the best!
Thank you sir
sir u already used density of water what density r u looking for ? plz need to know
We are looking for the density of the object.
thank you so much.......that was so helpful
owo Great sir...salute...
where did 5000 came from sir? whats the sequence of division that u did?
First divide 40 by 9.8. Then divide that result by 8.16 x 10^-4
@@MichelvanBiezen thank you so much.... really helped me
micheal van Biezen literally saved me
what if the density is given and the missing is the weight submerged in water?
You work the problem the same way, but backwards.
@@MichelvanBiezen will you please show me?
If you know the density and the weight in air: density = mass / volume, you can find the object's volume. Then you can find the buoyancy force = (density of fluid) (volume of object) (g) Then you find the weight in water = weight in air - buoyancy force.
is the answer at the end for the volume or the pressure?
The answer is density. (that is the symbol for density)

Hello sir, my scical says 5.0020008×10^-5
How was it 5000? That's the only part of this video that I did not understand 😓
Did you perhaps move the decimal point after the 2 because the density of water was 1000? Please I dont understand 😭
It is a matter of "significant" figures. (See the playlist on significant figures). In the calculation leading up to the final answer the buoyancy force was 8 N which only has one significant figure, so technically our answer should only have one significant figure.
really helped me
Very helpful, thank you!
Glad it was helpful!
So if we lived without an atmosphere, would we weight different?
We would weigh about 3 ounces more (80 grams)
I hope you're my professor :(
Thank you
You're welcome
Really helpful video. Last part though .. lol....
At 4:52 is density not V please
Correct. If you watch the video to the end, you will see the correction.
Why I am getting 5002
You may have a rounding error. (Don't round intermediate results)
@@MichelvanBiezen thanks sir
Whoohooo I got it. 😀
So clever
So clear and understandable
How come 5000 is the answer?
What specifically are you wondering about?
💜💜
glup....me excuses....I wrote my doubt before to see the final video... Now I have watch the mistake. Please forget me previous question. thank you.
No problem. It was a good catch.
🙏🙏
You are welcome.
How is the answer here 5000? I got 5.00x10^-4 whatttttt
What are your units? the answer is 5000 kg/m^3
