Scientists discovered two new planets: planet X and planet Y. They have identical volumes, but the mass of planet X is two times greater than the mass of planet Y. If two identical space probes land on each planet, which of the following will be true?
A. The weight of the space probe on planet X will be greater than the weight of the space probe on planet Y.
B. The weight of the space probe on planet Y will be greater than the weight of the space probe on planet X.
C. The mass of the space probe on planet X will be greater than the mass of the space probe on planet Y.
D. The mass of the space probe on planet Y will be greater than the mass of the space probe on planet X.
A. The weight of the space probe on planet X will be greater than the weight of the space probe on planet Y.
Weight is determined by the force of gravity acting on an object, which is directly proportional to the mass of the object. Since planet X has a greater mass than planet Y, the force of gravity will be greater on planet X. As a result, the weight of the space probe on planet X will be greater than the weight of the space probe on planet Y.
