(a) if the masses of earth and the moon were both doubled, by how much would the radius of the moon's orbit about earth have to change if its speed did not change? (assume that rem is the mean distance between earth and the moon before changing of the mass, r′em is the mean distance between earth and the moon after changing of the ) by how much would its speed have to change if its radius did not change? justify your answer.
