- From the information in Figure 15.21, estimate the speed with which the particles in the CME in parts (c) and (d) are moving away from the Sun. Figure 15.21 Flare and Coronal Mass Ejection. This sequence of four images shows the evolution over time of a giant eruption on the Sun. (a) The event began at the location of a sunspot group, and (b) a flare is seen in far-ultraviolet light. (c) Fourteen hours later, a CME is seen blasting out into space. (d) Three hours later, this CME has expanded to form a giant cloud of particles escaping from the Sun and is beginning the journey out into the solar system. The white circle in (c) and (d) shows the diameter of the solar photosphere. The larger dark area shows where light from the Sun has been blocked out by a specially designed instrument to make it possible to see the faint emission from the corona.

Estimate the fractional mass loss of the Sun over 109 yr due to the emission of neutrinos. The mass of the Sun is 1.989 × 1030 kg.

- What is the approximate temperature of the sun at its chromosphere ?arrow_forwardWhy was the Davis experiment only able to detect one-third of the neutrinos originally predicted? Most of the neutrinos were absorbed by Earth’s atmosphere. The neutrinos combined with other particles as they entered Earth’s atmosphere. The neutrinos distributed evenly among three different flavors while traveling to Earth. The number of neutrinos was too great to be held in the tank that Davis designed. The other two-thirds of neutrinos dissipated while traveling to Earth.arrow_forwardThe energy flux carried by neutrinos from the Sun is estimated to be on the order of 0.400 W/m2 at the Earth's surface.
