Hello, I have a question about this task. Why is in the solution The circumference is 2*hb+bB? I thought it was 2*hb+bB. I hope for some answers. Thank you!
Do magnets work in the weightlessness of space?
I have a task in process engineering: Two different containers have the same volume, the same height and The lowest point has the same small outlet opening. One container is a hemisphere, the other a cylinder (dashed cross-section). Which Will the container leak faster? I hope someone can answer this for me.
Hello folks I wanted to ask something: Do you have any questions that make me think? They might be questions that don't have answers, for example. I could talk to my physics teacher about them, but they should be physics questions. Thanks! Lg
If you rub your face with a so-called "aftershave," which usually contains alcohol, you'll feel a strong cooling sensation. What is the reason for this? Is my answer correct for, for example, an exam answer? The fastest particles escape from the surface of the aftershave. The average velocity of the remaining particles decreases. This is…
Max leaves the house with his backpack (m = 11 kg) and walks 250 m horizontally to his school. How much purely mechanical work does he do on the backpack? I thought 26,977 J, but it says "horizontal" and I'm confused. Could you please answer that for me?

“in the school our teacher showed us so: rges= 1/r1+ 1/r2”
There either the teacher has pawed, or you have written off incorrectly: a resistance can never be at the same time its reciprocal value…
Rather, it is correct: 1/Rges= 1/R1 + 1/R2 + [1/R(3 to n)] (small “r” stands in M and Ph for radius, not for resistance (resistant)
“on youtube stands but rges= r1x r2 r2 +r1”
1) stands for YT nothing…
2) must mean: Rges = R1 x R2 / (R1 + R2) -> which is the same equation as above, only reshaped according to Rges.
