is there any object with a density of exactly 1 just like water? and if so, would it float or sink? assuming that the object wouldnt disolve in water and its a physical object
+Masta An Yes, there are some objects with the same density as water. When an object is submerged in a fluid that has the same density as the object, it's called neutrally buoyant. When this occurs, the buoyant force acting on the object perfectly cancels out the objects weight, so you could literally set a cube that was neutrally buoyant in the center of a tank of water, not touching the bottom or floating, and it would just remain wherever you put it.
But... All atoms don´t have the same weight... Actually no one has! So your example is a little weird even if it´s easy to understand. I give you that... But if you ever jump to Mole or Avogadros constant with the same type of nonsense, you will feel the katana once more at your throat.
you really shouldn't be putting up wrong answers on your tutorial videos... if some little kid tries to calculate the density they will think they got an answer wrong (when they compare the correct answer they got to your wrong answer) then feel like they aren't good at learning; potentially discouraging them from learning physics.
Doesn't it seem like spacetime is compressed around massive objects? Just as it seems that spacetime compresses when you travel through it with acceleration. I wonder...Do objects in a gravitational field also shrink in one dimension with the place of the gravitational acceleration? It would seem so...Has anyone figured that mass does not bend spacetime, rather compresses it? The graphic of the planet over the funneling grid is just so ridiculous...imagine a 3d grid...place the planet into it...the grid expands out in a fisheye as if spacetime and matter could not exist together...this creates the gravitational effect...not a 2d piece of latex with a bowling ball stretching it down in the center...if space time is being compressed and not just apparently bent, wouldn't that mean that spacetime is not homogenous? and then...do we really need dark matter or energy anymore? I think not...I think they shall not find it...how can you bend something and not change it's internal geometry...? What force would be pulling the planet into the 2d grid anyway? Its really a very incomplete model for gravity...My model features a 3d grid and compression is the force which bends spacetime into increasingly larger and larger, but weaker and weaker spherical zones of spacetime compression...creates all the same effects of the bending model...What do I figure is actually compressing? The gluon field...a proven vacuum energy that permeates all of space...I figure when you get a bunch of matter compressed into a smaller and smaller area, the gluon field energy is not enough to support all those quarks and nucleons...so, the field of spacetime bends inward from all directions...akin to being compressed...and yes...it would shrink matter in one direction...spacetime is not actually more concentrated in these areas of compression...the "amount" of spacetime experienced relatively, is less...black holes compress spacetime down to nothing...there is nothing for light to travel through...it has been smashed out of existence...not stretched, as modern day physicists like to envision...when we travel through spacetime faster and faster, we experience less of it relatively because of our motion though it...and it shrinks...less time and less space in one direction...Where does a guy like me take ideas like this...? Thanks for all the videos...very inspiring :)
Yeah, it should be 19.27 kg/L, rather than the 27.37 kg/L he mentions in the video...as others have noted, it could very well be because he accidentally chose 2.38 L instead of 3.38 L for the volume.
I thought I was going crazy!! Teaching myself physics and electricity from TH-cam and it's not been the easiest. I was going to pull my hair out if the answer was not 19.27! Lol
Guys, for object A, the density is: 19.27kg/L
Object B, the density is: 0.64kg/L
ty bro doing edpuzzle rn😭😭🙏
Change it to 0.5 speed and it sounds like he wants to die XD
xD
try 0.25 and it sounds better/worse
XDD
😂😂
For Object A it appears he used an incorrect volume of 2.38 L as opposed to 3.38 L.
ya I was wondering why my calculations were off thank you
Yeah bc I got a density of 19.27 kg/L
Mystery solved
yes! this was driving me crazy. glad someone else saw it
You are great sir. At age of 30,I m learning these things practically. :D. Thks so much from India :)
Nice work sir for every student of any country
I have a question, how did he get 27.37kg for block A as I got 19.27 or rounded 20?
How in the heck did you get 27.37 kg/L???
Look below, he screwed up. I got 19.27 kg/L
Density of obj A should be 19.27
really helped me out with this, thank you

cool. thanks
Masta An np
this was made in 2014 why is the quality so good
call me crazy, but the units for density are g/cubic cm yes? Fresh water for example is 1 g/cubic cm
My smart Period 8 class thinks your calculation is incorrect for the density of object A.
You have 8 classes?! I only have 6 classes.
Ally Walters... only 6???I have 11🤭
@Connor Barnhill gah dayum👴🏿
@Connor Barnhill I have 17
@@sylsamvies565 I have 4????
A is 19.27
Round up
yes
Greatly appreciated! Thanks:)
Excuse me can i ask what is the program u r using for teaching that???
I'm confused.......
Thank you so much u made me get an A+
Yeah, Yeah sure
HE ALMOST HAS 1MIL SUBS WHOAAAAAAAAAA
The math for block A is incorrect. This made me more confused than I already was.
great video man keep it up
(Your density for block a is wrong- my class AND my teacher agree)
Totally awesome!
I can't find this in edmodo so I come to TH-cam, the same video
Epic video
thank you
im so confused!
try explaining this to a flat earther...they think density is a replacement for gravity.
is the second one 19.27
i am confused
It's because it isn't gravity that causes things to accelerate, it's the medium and it's relationship with matter that does.
The density of #1 is 19.27
This video was very helpful thank you so much
Online teacher posted this video because she doesn't teach anything, and the answer to block A is wrong smh.
He go the density for object A wrong, I think. could be wrong
block A is confusing af
Hi! I am a high school teacher. Which software do you use for making your videos?
Do you realise that gravity is not a force...but you teach children that it is? What's the point in teaching false science to children?
this was helpful.
thank you

A = 19.23kg/L, B = 0.64Kg/L
Thats what I got!!?
Why is your answer different for A?
Michael Pyott
me too im confused.
Michael Pyott He divided by 2.38L instead of 3.38L for some reason.
+Desmond G Oh, god, I was so confused...
wow
cool
Hi guys
Hi
I got for B = O.64 Kg/L and for A = 19. 27 Kg/L
wassup guys
Nice vid he he he ha👌👌👌👌👌👌👌👌👌👌😤😤😤😤
hey heyy, you like huey lewis and the news?
This was no help
Agree everyone is saying so much help it not
i dont like 8th grade :(((((
I in 7th and I learning this
Oof
this is so unhelpful
Yeah not helpful you didn't explain enough

Thx for letting us know KAREN, literally everyone else says it was decent and/or good
@@S_U_M_E_R lol its a joke. idc about chemistry as I am only in it because of the credits buckaroo
I think this was just toooooooo easy.
your caculation have an error

yes it is i think he just presses 2 withut realising it
