Yes, it is, this is taken into account because you add the 0.158 MeV/c momentum term to the total beforehand energy. You add the rest mass energies, and the momentum energies to get the total energy in your frame.

Hey, sorry to bother you, i was hoping you could help me solve this please:

There is a cube made out of wire with cubes brim resistance of 6 ohms.
Whats the voltage between diametrical oposite cube tops, if there is a 2A electric current flowing?
What is this cubes resistanace?

Its 5 ohms

Although I am working on a phd in electrical engineering, I am surprisingly bad at elementary circuits... I assume the answer is not using V = IR, and a function of the geometry of the system. To be honest I don't understand the question- how is a cube made from wire, what is "brim resistance", and what is a "cube top"?

It sounds like an interesting puzzle.

You're the only one who seems to know this, please go to the original forum and see if my assumption is correct? and explain further how you got your answer please.
