Answer:
In pair production, after the loss of Kinetic energy, the angular separation between the two photons is 180°.
Explanation:
- Pair production is the process of formation of two electrons, one negative and the other positive (positron), from a pulse of electromagnetic energy traveling through matter.
- It is a process of direct conversion of radiant energy to matter.
- The sum of the Kinetic energies of the formed particles amounts to a value of 4 MeV.
- When the kinetic energy is lost, emission of two photons, each with an energy of approximately 1 MeV in the form of gamma rays takes place ( in opposite direction).
Therefore, the angle of separation between the two photons is 180°.

The answer is C. F=ma basically says that force is a function of mass multiplied by acceleration. The first two answers don’t make sense because there’s no necessary relationship between mass and acceleration. And for the last two, the higher the mass, the higher the force needed, therefore C is the correct answer.
Answer:
emf = 11.667 V
Explanation:
Given: charge q = 0.060 C, electric potential energy E =0.70 J,
Solution :
by definition 1 volt = 1 joule per coulomb
so Voltage = emf = E/C
emf = 0.70 J / 0.060 C
emf = 11.667 V
