Electrostatics: When is it positively charged and when is it negatively charged (electroscope)?
BySeimenk
We're currently studying electrostatics in physics, and tomorrow we'll have a test on the electroscope. I have seen that if, for example, you rub a balloon and wipe it off the plate of the electroscope, the negative charges of the balloon are released, including negative ones due to charge separation. In another example, I saw…
Why cosine in the envelope function?
I understand the derivation, but when I was asked why the cosine function and not the sine function is used for the enveloping function, I didn't know either. In order not to be misunderstood: I understand that in u(t) the sine part is the beat frequency, since the frequencies are added together, but I do…

Which is more effective, sunlight or full moon?
I wanted to ask which is more effective. I'm planning to use my solar panel again soon to charge my battery or my cell phone. Which is more effective: sunlight or a full moon?
No, the extension is taken into account during the construction or laying of the tracks.
The following WP article addresses the topic:
In order to answer the question, in the case of unfavorable conditions, distortions can occur in classical track construction.
Yes, there were tracks with distortions.
1964 or so it was. Was in my choke book

No. They think about it and build expansion joints.
Magnificently, if you have no idea and just blubbert like a fish.
There is no track with expansion joints
Do you think Zuggleise?
No. That was all planned.
