Final answer:
The question is incomplete as the representations by Sara and Sam are missing. Nonetheless, Jupiter's mass is measured in kilograms or Earth's masses, and an astronaut would experience greater gravitational force on Jupiter compared to Earth, resulting in a higher reading on a scale.
Step-by-step explanation:
The question pertains to the mass of Jupiter and seems to offer options to choose from regarding who represented Jupiter’s mass correctly. However, since Sara and Sam’s representations of Jupiter’s mass are not provided in the question, we cannot determine the correct answer. Hence, the question is incomplete. Nevertheless, we can discuss the appropriate units of mass used in astronomy. In astronomical contexts, the mass of a planet like Jupiter is typically measured in kilograms (kg) or in terms of the mass of the Earth (‘Earth’, where 1 Earth is the mass of our own planet). Jupiter's mass is approximately 1.898 × 1027 kg or about 317.8 times the mass of Earth.
Regarding the hypothetical scenario presented in part D, the astronaut would fall faster into Jupiter than she would on Earth due to Jupiter’s higher mass and thus greater gravitational pull. If she were to fall feet first into Jupiter in a capsule with a scale, the scale would show a significantly increased weight compared to her weight on Earth, again due to the stronger gravity of Jupiter. The exact force would depend on the local gravitational acceleration at Jupiter’s atmosphere where the scale is located.
