I'm trying to do a lab for my physics class. It wants me to calculate the weight of the water displaced when I put a 500-g mass in a cup of water. I know the volume which is 59.0 ml. And I also know that the Buoyant force i s 0.56 N. I thought that the Buoyant force equals the volume of the...

My last final was over at 3:30 today, Finally! (haha, pun fully intended ) Man it feels good to be done with finals. I aced that final too, although it was particularly grueling and took me nearly 5 hours to complete (and I was one of the first done) So I just had to celebrate, anyone else in...

Hi, I'm new here so I'm not sure how formal this should be: I have studied electromagnetism in my Physics AP class at my high school but I have had a question at the back of my head. I don't have a very good physics teacher, and he was unable to explain this to me. My question is why, when...
