Herman Trivilino's latest activity

No it doesn't! Gravity tends to move things closer together, because the gravitational force is always attractive. Part of your...

Thank you very much for all the help and explanation kuruman, jbriggs444, Lnewqban, Herman Trivilino, Gavran, haruspex

That's the only way to do it! After all, the 3 m height of the poles has no effect on the distance from the top.

Start with a free-body diagram of the point where the 25 kg object hangs from the nylon rope.

its in the first picture. all the way to the right. :)

Can you show us that calculation? Or at least the value of the force?

Mechanical energy is conserved only if the collision is perfectly elastic. There is no change in temperature. Is that the same thing as...

Usually it's the ratio of speed after to speed before.

I would advise against writing the equation this way as it can introduce sign errors and it doesn't generalize easily to a situation...

My guess would be an almost definite "yes". Air conditioning techs deal with "high voltage" circuits connected to the mains that power...

The "low" voltage is not relevant. It just means it's lower than some other voltage in another circuit. But there are other circuits...

It's used to describe the increase in pressure with depth.

Does the unlabeled chord pass through the circle's center?

I guess it's too much trouble for you to post a graphic of what you are talking about.

Because the correct equation is ##E_o=mc^2## where ##E_o## is the so-called rest energy. Rest energy is one of Einstein's greatest...
