The weight of an object depends on the force of gravity acting on it. On which planet would a given object weigh the most?
(1 point)
Jupiter
Mars
Earth
• Saturn

Answer 1

The weight of an object depends on the surface gravity of the planet. Referring to the provided data, we can compare the surface gravity (compared to Earth) for each planet:

• Venus: 0.90
• Earth: 1.0
• Mars: 0.38
• Jupiter: 2.53
• Saturn: 1.06
• Neptune: 1.14

Based on this comparison, Jupiter has the highest surface gravity (2.53 times that of Earth), meaning an object would weigh the most on Jupiter.

Answer: Jupiter

Answer 2

The weight of an object depends on the force of gravity acting on it. On which planet would a given object weigh the most?
(1 point)
• Jupiter
• Mars
• Earth
• Saturn

Answer 3

To determine which planet a given object would weigh the most on, we need to look at the surface gravity compared to Earth:

• Jupiter: 2.53 (2.53 times Earth's gravity)
• Earth: 1.0 (1 times Earth's gravity)
• Saturn: 1.06 (1.06 times Earth's gravity)
• Mars: 0.38 (0.38 times Earth's gravity)

Since Jupiter has the highest surface gravity, an object would weigh the most on Jupiter.

Answer: Jupiter

Answer 4

Which planet takes the longest to complete one revolution around the sun?
(1 point)
Venus
• Saturn
Earth
• Neptune

Answer 5

The time it takes for a planet to complete one revolution around the Sun is known as its orbital period or length of year. From the provided data, the lengths of years for the planets mentioned are as follows:

• Venus: 0.62 Earth years
• Earth: 1.0 Earth years
• Saturn: 29.4 Earth years
• Neptune: 164.8 Earth years

Among these, Neptune, with a period of 164.8 Earth years, takes the longest to complete one revolution around the Sun.

Answer: Neptune

Answer 6

The planet Uranus is between Saturn and Neptune. What is a reasonable estimate for the distance, in AU, from Uranus to the sun?

Answer 7

To estimate the distance of Uranus from the Sun in astronomical units (AU), we can look at the distances of Saturn and Neptune:

• Saturn: 9.5 AU from the Sun
• Neptune: 30 AU from the Sun

Since Uranus is between Saturn and Neptune, its distance would be greater than 9.5 AU and less than 30 AU. Therefore, a reasonable estimate for the distance of Uranus from the Sun would be somewhere between these values.

The options provided are:

• 4 AU
• 8 AU
• 20 AU
• 32 AU

Since Uranus is closer to 20 AU than to the other values, we can conclude that 20 AU is a reasonable estimate for its distance from the Sun.

Answer: 20 AU
