Use the table to answer the question. Planet W=estimated mass of planet 6.4. Planet X=estimated mass of planet 3.3. Y=estimated mass of planet. Z=estimated mass of planet 48.7. Assuming these planets were similar in radius, which planet would an object weigh the most?

Answer 1

To determine which planet an object would weigh the most on, we need to consider the gravitational force, which is proportional to the mass of the planet. The weight of an object on a planet can be calculated using the formula:

\[ \text{Weight} = \text{mass of the object} \times \text{gravity} \]

Since the radius of the planets is assumed to be similar, the gravitational acceleration (gravity) can be simplified to depend on the mass of the planet alone.

From your data, the estimated masses of the planets are:

• Planet W: 6.4
• Planet X: 3.3
• Planet Y: (not provided)
• Planet Z: 48.7

Based on the masses provided, the weights of an object would be highest on the planet with the greatest mass, which is Planet Z with an estimated mass of 48.7.

Thus, an object would weigh the most on Planet Z.
