So you don't know you can convert weight to volume.
That's where you are confused.
If it states that mass will be displaced, you can get it's equivalence in volume(liquid).

Don't mind him. He doesn't know. A whole lot of people shouting Archimedes Principle here don't understand how it works in practice.

Infact, the whole essence of Archimedes principle is hinged on conversion of volumes to mass.

Donmobi:

Perhaps not fully surveyed upon.
The principle states that an object displaces it's own volume when inserted in a liquid.
So yeah you can't explain this without that.

how can the object displace its own volume. It has to be weight. Can a floater or football displace its own volume when thrown into water?

Alexanderobi:
The answer is 23.5

When acid is added to a metal, hydrogen is given off

what is dis one insinuating self hope you pass jeleosinmi

This Explains The part Of The Law That Said "Partially Or Fully"... As You Said If 1g Only isImmersed Then 9g Remains And Only 1g Is Lost Or Equal To The Displaced Fluid...

PatrickOkunima:


Don't argue what you have no idea about. There's a lot of difference. He said, mass of the object = mass of liquid displaced. Whereas, Archimedes states that the loss of weight the object experiences is equal to the mass of liquid displaced. I'll explain. If an object weighs 10KG. For instance, it's weight drops to 9KG when immersed in a fluid, it only loses 1KG. The 1KG it loses is the mass of the displaced fluid, not 10KG.

It's quite weird how most people here are struggling to get why the answer is B.
Others are basically misquoting Archimedes.

Now here's the principle.

It states that when an object is partially or fully immersed in a fluid, it experiences an upward force which equals the weight of of fluid displaced. Whereas an object would always displaces it's own volume when inserted in a fluid.
Small volume, small volume displaced.
Thus, B.

Is C a Hollow object?

You are one of the problem we have in Nigeria

PatrickOkunima:


What you wrote there is not Archimedes principle. According to Archimede's principles, when an object is immersed in a fluid (liquid or gas), it experiences a loss in weight equal to the mass of the liquid displaced.

you are both saying the same thing na, oga mi

B

.

It's B .

E or F

falcon01:
Is C a Hollow object?

It's B. Hollow object can't sink to the bottom. B has the smallest body mass

RepoMan007:
how can the object displace its own volume. It has to be weight. Can a floater or football displace its own volume when thrown into water?

Yes. If 1/3rd of the ball floats in water, it displaces one third of a volume of water.

Donmobi:

Yes. If 1/3rd of the ball floats in water, it displaces one third of a volume of water.

but 1/3rd is not same as the ball volume?

B.
It contains just pin that doesn't occupy space unlike the rest.

PatrickOkunima:


What you wrote there is not Archimedes principle. According to Archimede's principles, when an object is immersed in a fluid (liquid or gas), it experiences a loss in weight equal to the mass of the liquid displaced.

You sure say OP and his cohorts never troway displaced water from the glasses to make the current water level equal, before dem give us pinshure?

B

CivilianJTF:
B

Archimedes principle: Weight of object immersed equals weight of liquid displaced.

B has negligible weight, occupying negligible space in the cup, hence more water in the cup.

#Secondary school physics#

You think that principle holds here? As long as the object can sink, the weight does not matter but size.

Donmobi:

No we don't.
It's very simple to deduct the answer.

You are partly correct, if you reason like unscientific person.

It's like arguing that folding a piece of paper 42times will reach the moon. Mathematically correct, but practically impossible. So a mathematician would understand better, but an ordinary man would find it difficult to understand.

So you're all looking at a face value of images. What if the pair of scissors is a paper image dip inside the water? Or the wrist watch is a mirror image on the glass?

A doctor would not issue you a medicine without proper diagnosis of your ailments.

B

The answer is option B, only if all the objects are inside the respective Glass cup.
Otherwise, it is difficult to tell since the Glass cup is transparent and some or all the objects could have been outside the corresponding Glass cup(s).

CivilianJTF:


What what have you said now... what's the difference? You need to read and know more about Applications of laws.

He just de cram theory. Loooooooooool. Well-done bro.

richmond500:
Oga, this isn't physics but just normal question

What you need is normal water at room temperature, when you start to bring in those parameters, u are moving away from normal.

Yeah, I know right. And that's the problem. All these conditions where not stated in the question for proper clarity.

What is "normal water" by the way?

Ojukwu007:
Intelligent ladies always make my day. Seagodess, what sacrifice should I bring to your sea? Well done.

lolz..

squash47:

What if the other three items, except the pin, have equal weight, thus creating similar effect 🤔

I don't is about the weight but the space each item occupied in the glass cup, though the liquid there may equal

PatrickOkunima:


What you wrote there is not Archimedes principle. According to Archimede's principles, when an object is immersed in a fluid (liquid or gas), it experiences a loss in weight equal to the mass of the liquid displaced.

...and how is this different from what he said.

RepoMan007:
but 1/3rd is not same as the ball volume?

That's the point.
1/3rd of the volume immersed displaces1/3rd volume of fluid.
Same goes if it's fully immersed, it displaces it's whole volume.

chibestjerry:

Which of the Glass has more water?
A?
B?
C?
D?

YOU HAVE TO TELL US THE MATERIALS USED TO MAKE THOSE OBJECTS IN THE WATER BEFORE WE CAN PICK CORRECT ANSWER.

CaptainFM1:


Yeah, I know right. And that's the problem. All these conditions where not stated in the question for proper clarity.

What is "normal water" by the way?

normal water is the water you drink at home which has room temperature.

TBH, You do not need those parameters to answer the question

Nah.
This is just a test question. When the principles are duly applied, you're sure of getting the answer.

B

When I see 60% of people will fail this,then I know their is no water in it,
