At the rate at which the Sun is losing mass in the solar wind, how many years will it take the Sun to lose as much mass as Uranus?

It will take ___ × 10⁸ years.

Expert Solution

We know that the rate of emission of energy from the Sun's surface is = 3.8 x 10²⁶ W

Now as :

Rate at which E is produced = Rate at which mass M is lost by the Sun x c²

where c is the speed of light

Substituting values we get the rate at which the mass is lost by the sun:

As Mass of the Uranus is = 8.68 x 10²⁵ kg

Therefore the time taken to lose that amount of mass will be:

Substituting values we get:

Converting time into years we get:

The table below shows how much of the mass of the Sun and the Earth are made up of each element (by mass). Note that, for this problem, the amounts have been randomized somewhat from their real values. For your answers to this problem, use the values given in the table below. Note that because of rounding, uncertainties in the known values, the applied randomization, and small differences between the solar nebula composition and the composition of the Sun, it...

1. The Lifetime of the Sun. The total mass of the sun is about 2 x 1030 kg, of which about 75% was hydrogen when the sun formed. However, only about 13% of this hydrogen ever becomes available for fusion in the core. The rest remains in layers of the sun where the temperature is too low for fusion. a) Use the given data to calculate the total mass of hydrogen available for fusion over the lifetime of the...
