I'm just curious... and do you like give these problems to your students as extra credit? lol I teach high school physics (gr 11-12). I do not give these as extra credit. Nice! I wish my teachers back in high school were awesome enough to play Starcraft. Unfortunately, they were all really lame :/ | ||

I certainly couldn't've come up with the correct answer but after reading MasterOfChaos' and others' posts it seems like B is reasonable to me. When inside the iceberg the railroad spike causes additional displacement due to its weight/mass but once it sinks to the bottom it will cause less displacement since only it's volume will matter and not it's mass/weight. | ||

Answer is definitely E. You can treat each object the same according to Archimedes principle. Since each of lower or higher density objects are inside the icebergs respectively (ice, water, spike), this gets taken into account in how low each iceberg sits in the water. Thus, each iceberg will displace as much volume as proportional to its buoyancy. Therefore, no water level will change. Gene removed his answer so.. I am assuming micronesia doesn't care about this topic anymore though. Most of you guys choosing B is kinda amusing namely because unfrozen water is more dense than ice (same as the spike). Thus, if you chose B you SHOULD also being saying that the water level would be lower for iceberg with water inside it too which is obviously not the case as you reasoned out. | ||

I was joking about Gene. This is still up for grabs. | ||
