I've got this question (attached as jpg) about the neutrino fluxes at earth. I don't know how to use the branching ratios in order to solve it. (Do I really need these ratios?)
Thanks.
Ted.

Neutrino fluxes at Earth refer to the number of neutrinos that pass through a given area on Earth per unit time. Neutrinos are subatomic particles that have very little mass and are constantly traveling through space, including through the Earth.
Neutrino fluxes are measured using large detectors, such as the Super-Kamiokande detector in Japan. These detectors are sensitive to the faint signals of neutrinos passing through them, and can measure the direction, energy, and type of neutrinos that are detected.
The main source of neutrino fluxes at Earth is the Sun. Nuclear reactions in the Sun's core produce high-energy neutrinos that constantly travel towards Earth. Other sources of neutrinos include supernovae, cosmic rays, and nuclear reactors.
Neutrino fluxes have very little effect on the Earth itself, as they have almost no interaction with matter. However, studying neutrino fluxes can provide valuable information about the processes happening in the Sun and other celestial bodies, and can also help us understand the fundamental properties of neutrinos.
No, neutrino fluxes are not harmful to humans. They have very little mass and do not have enough energy to interact with our bodies. In fact, neutrinos are constantly passing through our bodies without us even noticing.
