The electron and positron collide and annihilate each other, converting their total energy (sum of kinetic and rest energy) into energy carried by two photons:
2(1.64MeV + 0.511MeV) = 2
= 1.64MeV + 0.511MeV
= 2.15MeV
vector addition means combining all of the force acting on an object. if the forces are in opposite directions, how do you add t

To solve this problem we will apply the concepts related to the wavelength of its third harmonic.
It describes that the wavelength is equivalent to
Here,
The wavelength is in turn described as a function that depends on the change of the speed as a function of the frequency, that is to say
In this case the speed is equivalent to the speed of sound and the frequency was previously given, therefore
Finally the length of the pipe would be
