AI Thread Summary
The Y Meson has a rest mass of 9.6 GeV/c² and a measured width of 51 keV, which are crucial for calculating its lifetime. The relationship between energy and mass is highlighted through the equation E=mc². Participants expressed uncertainty about how the measured width relates to the meson's lifetime, with some speculating a connection to electric fields. Additional resources, such as a link to HyperPhysics, were suggested for further understanding. The discussion emphasizes the need for clarity on the relationship between energy width and particle lifetime.

Homework Statement



The Y Meson has a rest mass of 9.6 GeV/c2 and a measured width of (Delta)E= 51keV. What is its approximate lifetime (delta)t?

Homework Equations


E=MC2

And.. who knows?

The Attempt at a Solution



We came to the conclusion that 9.6 GeV/c2 was related to E=MC2.. and we pretty much had no idea with the measured width of (Delta)E= 51keV ( we thought it might be related to electric fields though).

Thread 'Rolling without slipping on a curved surface'

Kindly see the attached pdf. My attempt to solve it, is in it. I'm wondering if my solution is right. My idea is this: At any point of time, the ball may be assumed to be at an incline which is at an angle of θ(kindly see both the pics in the pdf file). The value of θ will continuously change and so will the value of friction. I'm not able to figure out, why my solution is wrong, if it is wrong .

TL;DR Summary: I would like to know the voltmeter readings on the two resistors separately in the picture in the following cases , When one of the keys is closed When both of them are opened (Knowing that the battery has negligible internal resistance) My thoughts for the first case , one of them must be 12 volt while the other is 0 The second case we'll I think both voltmeter readings should be 12 volt since they are both parallel to the battery and they involve the key within what the...

Thread 'Trying to understand the logic behind adding vectors with an angle between them'

My initial calculation was to subtract V1 from V2 to show that from the perspective of the second aircraft the first one is -300km/h. So i checked with ChatGPT and it said I cant just subtract them because I have an angle between them. So I dont understand the reasoning of it. Like why should a velocity be dependent on an angle? I was thinking about how it would look like if the planes where parallel to each other, and then how it look like if one is turning away and I dont see it. Since...
