what one i think is in chapter 3, something related to jirim. The difference would be ketumpatan lor, air masin has higher ketumpatan so daya tujah ke atas air masin should be higher than that of air tawar. Not very sure though, someone please confirm

ketumpatan, bab 3, ketumpatan bahan and USED IN GARIS Plimsoll under prinsip archimedes as well.

Basically, air masin has extra added salt in it and is more dense than air tawar. Therefore, the same ship which weighs the same, sinks more in air tawar and sinks LESS in salt water because of the berat air yang disesarkan.

good night guys. Sleep early for a fresh mind tomorrow

and look back in the earlier pages for the hot tips which you shouldn't rely too much on.

I heard alot of last minute rumours that experiment got something to do with the radioaktif? Anyone can confirm this.

I got one question, berat object equals to daya tujah ke atas right? regardless if part of the object is above water?

huh? i thought its because of hot/cold not acidity

it has nothing to do with hot/cold and acidity, just the ketumpatan. If ketumpatan increases, daya tujah ke atas also increase

radioaktif sure out. just duno paper 2 or paper3. mostly paper2

i aso duno wor... mayb i post 2 post 2gether.go back few page and u wil c tat

thank you

what can they ask about radioactive? Usually just calculate the energy release right? Neway, i gtg aleady.. didnt sleep yesterday, deadly tired now

how to kira kehilangan jisim semasa reputan in uja?

ohhh yeah i know now. thx for correcting me. a ship will submerged deeper in fresh water because the density of fresh water is less than sea water. so it must displace more water to obtain sufficient buoyant force to support its weight

the hot cold thing i got mix up coz a ship can float higher in the cold season as cold water has a higher density

isnt that in reference book?

cant find... and its called zarah alfa and beta, not sinar?

thats the best a form 4 student can do

radioaktif got 3 type la. alfa(4/2 he)beta(0/-1 e),gama(0/0 )
calculation include setengah hayat too..

Hay guys! Am I late?

Huh?! Slep when study juz now. Juz manage to finish a few chapter..
So ZzzZ...Guess i sleep now...

Good luck everyone....

it has something to do with hot/cold

if its is cold, ketumpatan increases making tujah ke atas higher

if it is hot, ketumpatan decreases making tujah ke atas lower.
