The sun is 60 ∘ above the horizon. Rays from the sun strike the
still surface of a pond and cast a shadow of a stick that is stuck
in the sandy bottom of the pond.
If the stick is 19 cm tall, how long is the shadow?

QUESTION 10 How do astrophysicists account for neutrino emission from the Sun? Solar flares create neutrinos with very energetic magnetic fields. Convection releases neutrinos, which random walk through the radiation zone. Fission in the Sun's core creates neutrinos when protons turn into neutrons. The annihilation of positrons and electrons in the core produces neutrinos. Fusion in the Sun's core creates neutrinos when protons turn into neutrons, QUESTION 11 How does the interstellar medium impact...
