I am retaking! :biggrin:

I got a C last year, God knows how I managed to do better in unit 2. I really want an A in physics so retaking for a UMS boost.

So there's this question.... I kinda have it memorised in my head after going through it a hundred times, but it would be nice to have a step by step explanation. It's on upthrust:
The relative density of ice is 0.917, whereas that of seawater is 1.025. What fraction of an iceberg is above the surface of the water?
Thanks :3

What textbook? Was it the context based approach (starting with HFS and EAT and SUR) because I too found that textbook appalling. I purchased the concept based textbook which I found much more useful. Either way the revision guides are very good at laying everything out clearly.

I believe it was. It was Red. The concept revision guide is great. and so it CGP but they are a little vague tbh.

I got 12% Dunno if its right though
So i subtracted 1.025-0.917 to get 0.108
(0.108/0.917) x 100 =11.77 ->>>> 12%

Im gonna attempt both the 2014 and 2014 R see how i do.
It should identify the areas im weak in.

find the difference in the density and divide it by the density of sea water.
(1.025-.917)/1.025 and multiply 100%, You'll get 10.54%

Aren't you finding the % relative to the iceberg?? wouldn't you divide by 0.917?

I don't think so....

:/ It's a weirddd question

The method our teacher showed was:
Realtive density= Density/ Density of water
therefore D of ice: 917kg/m3 seawater: 1025kg/m3

(Total volume-volume of object)1025= Total volume x 917

Volume over water: 0.105V
V being the total volume

someone explain??
