If a system is in a quantum pure state |a> then would the expected value be the eigenvalue? meaning if we know that the system is in the pure state |a> , then can we predict exactly the outcome of the measurement of the observable x ? which is ?

force is mass*acceleration.

we have a very small mass: 11.4*0.001 kg

if we want 0.035n of force, we need an acceleration:

0.035 = 11.4*0.001*a

a = 0.035/(11.4*0.001) m/s^2

when heated, the valance electrons increased their speed and transferred the heat from electron to electron.   i just took the test.
