Question

The solar wind carries mass away from the Sun at a rate of about 1.5 million tons per second (1 ton = 1000 kg). At this rate, how many years would it take for all of the Sun's mass to escape?

Answer 1

Answer:

1.75×10^12years

Explanation:

In one second, 1.5 million tons (1.5×10^6 tons = 1.5×10^6 × 1000kg = 1.5×10^9kg) of sun is carried away by solar wind

Mass of the sun = 1.989×10^30kg

Time for all of the sun's mass to escape = 1.989×10^30/1.5×10^9 × 1 sec = 1.326×10^21 sec × 1 year/7.57×10^8 sec = 1.75×10^12 years
