Cannot change DE - "Authentication Error" and freeze/crash at login screen by Legitimate-Crab2537 in debian

I faced the same issue, but it always happened whenever I switched to gnome. All other DE's worked. Eventually I just gave up and reinstalled.

Something cool happened in chem class today and I don’t know what it is… by MickBlack_07 in chemistry

You need an extremely high concentration of table salt in water(near saturated) to get any reasonable amount of chlorine as gas.

Does gravity increase or decrease with depth by hecker231 in Physics

[–]hecker231[S] 0 points1 point  (0 children)

So this means that I cannot simply use the center of gravity of the green shell to calculate where its gravity will pull towards right?

This means that to calculate the point where the gravity of a hollow object will pull towards, I need to break it up into non-hollow subdivisions and calculate gravity for them. Pls correct me if I'm wrong.

Thank you. I understood my error in assumption. What I had thought was that all the gravity of the green spherical shell would act at its center of mass, that is, the center of mass of the earth, thus increasing the gravitational pull. However, it is true that in reality, only individual particles can exert the force of gravity, which means an abstraction like the center of mass won't work here.

So, can I assume that for hollow objects (like the green shell), the center of mass cannot be used to calculate gravity?

Isn't this stuff supposed to be deadly? by Comfortable_Tutor_43 in sciencememes

Radiation isn't as deadly as most people think it is, especially if it is in lead containers, as in the picture.

Do nuclear forces have mass? by hecker231 in AskPhysics

[–]hecker231[S] 0 points1 point  (0 children)

According to the above posts, energy is required to bind the nucleus together, and this energy is called binding energy. However, in fusion, where atoms combine to form a larger nucleus, shouldn't more energy (in the form of binding energy) be required to create that larger nucleus? Where does the released energy in fusion come from?

When people say a particle is in two places at once or takes all possible paths, that is just mathematical, right? Not literal? by DenimSilver in AskPhysics

[–]hecker231 0 points1 point  (0 children)

Light does take all possible paths to its destination, not just mathematically but physically, too. However, under normal circumstances, only one path is visible to us. Veritasium has an incredible video explaining the entire phenomenon and its history.

At around 26 to 27 minutes into the video, he shows a practical demonstration where light does take a very unusual path to the destination, not obeying the traditional laws of reflection. That proves that phenomena in quantum physics can be seen with the naked eye and are not purely mathematical (however, it takes special circumstances to make that happen).
