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°.

A spring oscillator is designed with a mass of 0.231 kg. It operates while immersed in a damping fluid, selected so that the osc
ludmilkaskok [199]

Answer:

.487 s⁻¹

Explanation:

Let damping constant be τ . The equation of decreasing amplitude can be written as

A = A₀ e^{-\tau t

A / A₀ = e^{-\tau t

At t = 9.43 s , A / A₀ = .01

.01 = [e^{-\tau\times9.43

ln.01 = - 9.43 τ

-4.6 = -9.43τ

τ = .487 s⁻¹
