Calculating Atomic Mass: Solving for Pi Meson's Mass in AMU

AI Thread Summary
To convert the mass of a pi meson, which is 139 MeV/c^2, into atomic mass units (amu), one must use the conversion factor of 931.5 MeV/c^2 per amu. This means that the mass of the pi meson in amu is calculated by dividing 139 MeV/c^2 by 931.5 MeV/c^2. The result is approximately 0.149 amu. The discussion clarifies that amu is defined as 1/12 the mass of a carbon-12 atom, correcting earlier misconceptions about its relation to the mass of a proton. Understanding these conversions is essential for accurate calculations in particle physics.

A pi meson has mass of 139MeV/c^2. what is this in atomic mass?

HOw do i solve for this? what steps do I need to do, any examples you can give to help me with to solve?
Dx :wink:

Dx,

I made a mistake. The amu is not the mass of one proton, it is 1/12 the mass of a C12 atom.
 
I believe 1 amu is something like 812 MeV/c^2..bah...i don't know the exact number, its something in the 800's

EDIT: Its 931.5 MeV/c^2 for each amu
 
Thanks you guys are the bomb! :wink:
 

Thread 'Struggling to understand the concept of this question (ice cube in water optics question)'

TL;DR Summary: I came across this question from a Sri Lankan A-level textbook. Question - An ice cube with a length of 10 cm is immersed in water at 0 °C. An observer observes the ice cube from the water, and it seems to be 7.75 cm long. If the refractive index of water is 4/3, find the height of the ice cube immersed in the water. I could not understand how the apparent height of the ice cube in the water depends on the height of the ice cube immersed in the water. Does anyone have an...

Thread 'Variable mass system : water sprayed into a moving container'

Starting with the mass considerations #m(t)# is mass of water #M_{c}# mass of container and #M(t)# mass of total system $$M(t) = M_{C} + m(t)$$ $$\Rightarrow \frac{dM(t)}{dt} = \frac{dm(t)}{dt}$$ $$P_i = Mv + u \, dm$$ $$P_f = (M + dm)(v + dv)$$ $$\Delta P = M \, dv + (v - u) \, dm$$ $$F = \frac{dP}{dt} = M \frac{dv}{dt} + (v - u) \frac{dm}{dt}$$ $$F = u \frac{dm}{dt} = \rho A u^2$$ from conservation of momentum , the cannon recoils with the same force which it applies. $$\quad \frac{dm}{dt}...
