Question

select all the correct answers. an unmanned spacecraft leaves for venus. which statements about the spacecrafts journey are true? the weight of the spacecraft keeps changing. the mass of the spacecraft keeps changing. the weight of the spacecraft remains the same. the mass of the spacecraft remains the same. the gravitational pull on the spacecraft remains the same.

Explanation:

Mass is a measure of the amount of matter in an object and is constant regardless of location. Weight is the force exerted on an object due to gravity. As the spacecraft moves from Earth - where it starts its journey - to Venus, the gravitational pull it experiences changes because the gravitational acceleration of different celestial bodies is different. So, the weight of the spacecraft changes during its journey. The mass of the spacecraft remains the same as it is an intrinsic property of the matter in the spacecraft. The gravitational pull on the spacecraft changes as it moves through different gravitational fields of celestial bodies on its way to Venus.

Answer:

The mass of the spacecraft remains the same.
The weight of the spacecraft keeps changing.
