Comparison of First Cosmic Velocities for Planets

To compare the first cosmic velocities for the four planets mentioned in the table, we need to understand what the first cosmic velocity is and how it relates to the acceleration due to gravity (g) on each planet.

The first cosmic velocity, also known as the escape velocity, is the minimum velocity an object needs to escape the gravitational pull of a celestial body and move into space. It is determined by the mass and radius of the planet.

Let's compare the values of the acceleration due to gravity (g) for each planet and discuss how they relate to the first cosmic velocities.

- Venus: Acceleration due to gravity (g) = 8.87 m/s² [[1]] - Saturn: Acceleration due to gravity (g) = 11.54 m/s² [[1]] - Earth: Acceleration due to gravity (g) = 9.81 m/s² [[1]] - Jupiter: Acceleration due to gravity (g) = 25.8 m/s² [[1]]

Based on the given values, we can make the following comparisons:

1. Venus has the lowest acceleration due to gravity (g) among the four planets, with a value of 8.87 m/s². 2. Earth has a slightly higher acceleration due to gravity (g) compared to Venus, with a value of 9.81 m/s². 3. Saturn has a higher acceleration due to gravity (g) compared to both Venus and Earth, with a value of 11.54 m/s². 4. Jupiter has the highest acceleration due to gravity (g) among the four planets, with a value of 25.8 m/s².

Now, let's discuss how these values of acceleration due to gravity (g) relate to the first cosmic velocities for each planet.

The formula to calculate the first cosmic velocity (v) is given by:

v = √(2 * g * r)

Where: - v is the first cosmic velocity - g is the acceleration due to gravity - r is the radius of the planet

To compare the first cosmic velocities, we need to know the radius of each planet. Unfortunately, the table provided does not include the radius values. Therefore, without the radius values, we cannot accurately compare the first cosmic velocities for the four planets.

In conclusion, we can compare the values of acceleration due to gravity (g) for Venus, Saturn, Earth, and Jupiter, but without the radius values, we cannot compare the first cosmic velocities for these planets.

I hope this explanation helps! Let me know if you have any further questions.
