Answer the question in full details, thank you very much, Answer on the correct significant figures: A star of mass 1.87 x 10^31 kg and diameter 9.44 x 10^9 m rotates with a period of 26.0 days. Suddenly, the star changes size and rotates with a new period of 19.0 days. The mass of the star is conserved. Assuming a uniform (but different) density both before and after the size change, by what fraction doesits [ diameter change? In other words, what is (new diameter)/(old diameter)?
