Toothpick?
heyy
I have to do some calculations, so I wanted to ask how much an 8 cm long and 2 mm wide toothpick weighs. Please be as precise as possible đ

Hi, I'd like to find out how Einstein came to this conclusion. I understand the principle of relativity at a basic level and that, from a relativistic perspective, nothing is faster than light particles in a vacuum, but how did Einstein derive this conclusion? I would be happy to have various links and pages where…
The pictures below were taken in selfie mode on a mobile phone. I wonder where this small circle comes from, because if you cover the bulb of the lamp on the camera with something (like a hand or a piece of paper), you can no longer see this circle. I didn't move the phone during…
(b) It was initially stated that the angular momentum of (a) is conserved, and that this allows for some calculations. Why are the angular momentums of a) and b) the same? I mean, the speed is different.
Or is this just scaremongering
It's a physics homework assignment that I don't understand. Could you help me?
Hi, maybe I misunderstood the whole thought experiment, but isn't it actually the case that particles (or whatever you call them) behave differently when someone is watching? That's not the case with the Schrödinger's cat thought experiment. And the whole thing is based on the fact that we don't know how these particles will behave,…
Um das Gewicht eines Zahnstochers abzuschĂ€tzen, gibt es einige Faktoren zu berĂŒcksichtigen, darunter Material, Dichte und GröĂe. Die meisten herkömmlichen Zahnstocher bestehen aus Holz, typischerweise aus Birke oder Bambus. Wir können also grob das Volumen des Zahnstochers berechnen und dann mit der Dichte des Holzes multiplizieren, um das Gewicht zu ermitteln.
Mit einem Durchmesser von 2 mm (0.2 cm) und einer LĂ€nge von 8 cm:
Um das Gewicht zu ermitteln, multiplizieren wir das Volumen mit der Dichte:
Somit kann ein 8 cm langer und 2 mm dicker Zahnstocher etwa 0.151 Gramm wiegen. Beachten Sie, dass dies eine sehr grobe SchÀtzung ist. Unterschiede im Material, Feuchtigkeitsgehalt oder Verarbeitung können das Gewicht beeinflussen
Das habe ich von chatgpt, hilft dir das
I’m afraid I only have one with 65x2mm here. It weighs 0.15g.
Then we count 80/65*0,15 = 0,85g for 80mm đ
A 80x2mm Stocher should have about 0.16g. Add a 15mm piece from the middle.
The other 65mm Stochers I weighed now weigh only 0.13g.
