    Hi, can anyone help me solve the following questions?

    1.What was the peak wavelength of the CMB when R=0.5?
    a. What temperature does this correspond to?

    2. Two quarks named Susan and Nick existed in the early universe. Susan
    became part of a proton and Nick became part of a neutron. What are
    two potential fates for both Susan and Nick about an hour into the age of the
    universe?
