A new planet has been discovered and given the name Planet X. The mass of Planet X is estimated to be one-half that of Earth, and the radius of Planet X is estimated to be twice that of Earth. 1. The estimated mass and radius of Planet X are used to calculate the minimum escape speed, Vc, for an object launched from the surface of the planet. If the actual mass and/or radius of the planet are slightly different from the estimated values, how will the actual escape speed . for the surface of Planet X compare to U. ? (A) Va = Vc regardless of any difference in mass or radius. (B) Va > U. if the actual mass is greater and the actual radius is less than their estimated values. (C) Va > Vc if the actual mass is less and the actual radius is greater than their estimated values. (D) Va
