could you explain why we calculate dLrel (The angular momentum) of two mass elements not one? We calculate dLrel and than to find Lrel we integrate L from 0 to l/2. Why do that ? Couldnt we calculate dLrel of one mass element and than calculate L from 0 to l/2?

2 of 7 Question A2 a) Calculate the mass loss rate of the Sun M due to the solar wind flow. Assume average properties of the solar wind of number density 6 protons cm³, and a flow speed of 450 km s-1. Express your answer in units of both kg per year, and solar masses per year. b) Suppose the solar wind flow is perfectly radial. Calculate the expected rate of change of solar rotation frequency dw at the present time, based on conservation of angular momen- tum. Give your answer in units of rad s-1 y-1 (i.e., radians per second per year) and also in terms of fractional change per year, i.e., 1 du. w dt' Use a current solar rotation period of P = 25.38 days to calculate the current angular frequency of rotation w. The moment of inertia of a uniform sphere is MR². You can assume that the radius of the Sun is approximately constant, and the change in its moment of inertia due to the solar wind is only due to the mass loss.

Assume that the solar wind causes the Sun to lose mass at a rate of 2 x 10’ kg/s. If you assume the wind is emitted a constant rate, estimate the time (in units of Gyr =Gigayears = 10° years) that it will take the entire Sun to evaporate via its solar wind emission. (Of course, the rate won't be constant throughout the lifetime of the Sun---this is just a rough estimate to understand the timescale associated with this process.) [Hint: you need to look up a number and do several unit conversions; this is a *rate* problem. Enter your answer as an integer or decimal, NOT in scientific notation.]
