Agamma-ray photon changes into a proton-antiproton pair. ignoring momentum conservation, what must have been thewavelength of the photon (a) if the pair is stationary after creation, and (b) if each moves off at 0.6c. perpendicular to themotion of the photon? (c) assume that these interactions occur as the photon encounters a lead plate and that a leadnucleus participates in momentum conservation. in each case, what fraction of the photon’s energy must be absorbed bya lead nucleus?

hi there!

your question asks at which segment does freezing occur.

since we're talking about water, the freezing point of water will be 32 degrees fahrenheit or below.

hope this ! ~

need to see circuit to get time constant

d₁ = displacement of tern from arctic to antarctic = 11000 miles

d₂ = displacement of tern from antarctic to arctic =   - 11000 miles

d = total displacement for the journey

total displacement for the journey is given as

d = d₁ + d₂

d = 11000 + (-11000)

d = 0 miles

t₁ = time of travel from arctic to antarctic = 3 months = 3 x 30 days = 90 days

t₂ = time of travel from antarctic to arctic = 3 months = 3 x 30 days = 90 days

t = total time of travel

total time of travel is given as

t = t₁ + t₂

t = 90 + 90

t = 180 days

average velocity is given as

average velocity = total displacement/ total time

v = d/t

v = 0/180

v = 0 miles/day
