- Ok, you displace the who lot of 1kg water, how much is the volume? 1lt! - Zzz (38 bytes) 2012-06-18, 06:04:41 (669966)
- “displaced"=volume of wood submerged under water level - pgss (48 bytes) 2012-06-18, 06:12:29 (669968)
- no, i was very careful in making it 5x or 50x - pgss (91 bytes) 2012-06-18, 09:44:10 (670004)
- 1liter is the "REMAINING" undisplaced water - pgss (530 bytes) 2012-06-18, 09:06:13 (669997)
- are you insane? Can you say the same if there is 1g water, or even 1mg? - Zzz (114 bytes) 2012-06-18, 08:57:32 (669991)
- no, i can displace 10 or 100 liters! (无内容) - pgss (0 bytes) 2012-06-18, 08:47:49 (669990)
- So you can displace up to 1lt water, right? - Zzz (44 bytes) 2012-06-18, 08:39:59 (669989)
- displaced doesnt mean there was water in that space - pgss (77 bytes) 2012-06-18, 08:36:46 (669987)
- only because you said "DISPLACED volume,which can be quite large for 1 kg water" - Zzz (173 bytes) 2012-06-18, 08:23:27 (669983)
- only because, i don't understand why how large 1 liter measures matter (无内容) - pgss (0 bytes) 2012-06-18, 08:05:45 (669981)
- Interesting, why do you assume that I intend to remove a drop of water? (无内容) - Zzz (0 bytes) 2012-06-18, 06:42:57 (669972)
- I think it is displaced weight that matters. - cornbug (54 bytes) 2012-06-17, 23:48:09 (669936)
- 不是。2.3立方米的木头,2.5立方米的桶。只要0.2公斤的水 (无内容) - pgss (0 bytes) 2012-06-17, 23:39:22 (669933)
- 为什么不能?displaced volume can be larger than the volume remains (无内容) - pgss (0 bytes) 2012-06-17, 22:56:32 (669923)
