C. 430 N
D. 532 N

Answer :

To determine the gravitational acceleration on Uranus from the given information, you can follow these steps:

1. Understand the given weight: We know that a rock weighs 170 Newtons (N) on Uranus.

2. Know the mass of the rock: The mass of the rock is specified as 5 kilograms (kg).

3. Use the formula for weight: The formula to calculate weight is:

[tex]\[
\text{Weight} = \text{mass} \times \text{gravitational\_acceleration}
\][/tex]

4. Rearrange the formula to find gravitational acceleration:

[tex]\[
\text{gravitational\_acceleration} = \frac{\text{Weight}}{\text{mass}}
\][/tex]

5. Substitute the given values into the formula:

[tex]\[
\text{gravitational\_acceleration} = \frac{170 \, \text{N}}{5 \, \text{kg}}
\][/tex]

6. Calculate the gravitational acceleration:

[tex]\[
\text{gravitational\_acceleration} = 34.0 \, \text{m/s}^2
\][/tex]

This means the gravitational acceleration on Uranus is 34.0 m/s².
