Assuming the lost b0w9gzzv ac tgbh .c*.l* br1/mass carries away no angular momentum, what would the Sun’s new rotation rate be?(round to the nearest integer)$\approx$ $rad/s$ (Take the Sun’s current period to be about 30 days.) What would be its final KE in terms of its initial KE of today?$KE_{f}$= $KE_{i}$
