Homework Statement Three long straight parallell wires that conduct electricity called L1, L2 and L3. The angle at L2 is 90 degrees and the distance between L2 and L1, L3 is 0,50 meters. The current through the wires L1 and L3 is 300 A while the current in L2 is 600 A. Decide the resulting...

p = 101,3 kPa p = 101,3 kPa * 2 p = 202,6 kPa h = 10,34 m h = 10,34 m * 2 h = 20,68 m That's what my answer would be?

I mean that if you have for example an rectangle. And you can extend it. Then 3x and 2x isn't the same thing because if x = 4 then: 3 * 4 = 12 2 * 4 = 8

Yeah, but why is the pressure 2x larger than the pressure at the surface and not 3x?

Sorry if I'm slow but I still don't get why the answer is 20 m instead of closely 30 m.

I don't get it because if you get up to the sea surface then the pressure would be 101,3 kPa again according to the exercise. But if I am at 30 m and the pressure is 300 kPa wouldn't it be something like: 30 m = 300 kPa 20 m = 200 kPa 10 m = 100 kPa 0 m = 0 kPa I don't really get what you...

I'm very new to physics and I haven't learned exactly what everything is called yet. Sorry if I confuse you. 1. Homework Statement How deep do you have to dive in a lake to get the total pressure 3 times as large as the airpressure at the surface of the water (101,3 kPa)? Normal pressure...
