Question

An unmanned spacecraft leaves for Venus. Which statements about the spacecraft’s journey are true? 1 The weight of the spacecraft keeps changing. 2 The mass of the spacecraft keeps changing. 3 The weight of the spacecraft remains the same. 4 The mass of the spacecraft remains the same. 5 The gravitational pull on the spacecraft remains the same.

Answer 1

the mass of the spacecraft remains sames

Answer 2

the mass remains constant unless it is moving at the speed of light
and weight first becomes zero as it enters space and then increases after entering the field of Venus
so weight keeps on changing
