How much deeper does the barge lower?

AI Thread Summary
The discussion revolves around calculating how much deeper a rectangular barge sinks when a 400 kg block is loaded onto it. The key principle involved is Archimedes' principle, which states that the weight of the water displaced by the barge must equal the weight of the block. The barge's dimensions are 5 m long and 2 m wide, leading to a need to determine the additional volume displaced by the block. Participants highlight the importance of knowing the volume displaced and the area of the barge to find the solution more efficiently. Ultimately, the focus is on applying these concepts to find the exact depth increase of the barge.

Homework Statement


  1. A rectangular barge floats in freshwater. When a 400 kg block is loaded on the 5 m long by 2 m wide barge, the barge sinks a few centimeters deeper. How much deeper does the barge lower?

This is where I am stuck. My textbook doesn't talk much about this at all.

You've done all the hard work. How much deeper does the barge have to "sink" to displace the extra 0.4 m3?

Yes, but you could have got there a bit faster from knowing the volume displaced and the area.

TL;DR Summary: I would like to know the voltmeter readings on the two resistors separately in the picture in the following cases , When one of the keys is closed When both of them are opened (Knowing that the battery has negligible internal resistance) My thoughts for the first case , one of them must be 12 volt while the other is 0 The second case we'll I think both voltmeter readings should be 12 volt since they are both parallel to the battery and they involve the key within what the...

Thread 'Trying to understand the logic behind adding vectors with an angle between them'

My initial calculation was to subtract V1 from V2 to show that from the perspective of the second aircraft the first one is -300km/h. So i checked with ChatGPT and it said I cant just subtract them because I have an angle between them. So I dont understand the reasoning of it. Like why should a velocity be dependent on an angle? I was thinking about how it would look like if the planes where parallel to each other, and then how it look like if one is turning away and I dont see it. Since...
