Exercise:
The Sun .ekg radiates energy at a rate of about eW. abcliste abc How much does the Sun's mass decrease in one day? abc How long does it take for the Sun to lose a mass equal to that of Earth .ekg? abc Estimate how long the Sun could last if it radiated constantly at this rate. abcliste

Solution:
abcliste abc The Sun radiates in one day an energy of: E Pt .eJ This amount of energy is equivalent to a mass-loss of: m_d fracEc^ fracPtc^ .ekg .etonne This is equal to almost billion metric tons! abc For the Sun to lose Earth's mass it takes: t fracm_EarthIndexm_d .ed .ea This is around million years. abc At this rate the Sun could last for: t' fracm_SunIndexm_d .ed .ea That is around one thousand times longer than the age of the universe. abcliste
