Question

The table shows the masses of four planets.

Planets by Mass
Planet
Mass (kg)
Jupiter
2.4 x 1027
Mercury
3.3 x 1023
Earth
5.98 x 1024
Neptune
1.2 x 1027
Which lists these planets in order from least to greatest mass?
A Jupiter, Neptune, Earth, Mercury
B Mercury, Earth, Neptune, Jupiter
C Neptune, Jupiter, Mercury, Earth
D Mercury, Neptune, Earth, Jupiter
5) Using the table above, how many times larger is Jupiter than Neptune?
A 2.0 x 101
B 1.2 x 1027
C 2.0
D 1.2 x 101

Answer 1

The correct order of the planets by increasing mass is Mercury, Earth, Neptune, and Jupiter. Jupiter is exactly twice as massive as Neptune.

Step-by-step explanation:

The planets should be listed in order from least to greatest mass based on the data provided. The correct order, taking into account the mass of each planet in kilograms, would be:

1. Mercury: 3.3 x 1023 kg
2. Earth: 5.98 x 1024 kg
3. Neptune: 1.2 x 1027 kg
4. Jupiter: 2.4 x 1027 kg

Therefore, the correct answer to the first question is B Mercury, Earth, Neptune, Jupiter.

For the second question, since Jupiter's mass is 2.4 x 1027 kg and Neptune's mass is 1.2 x 1027 kg, Jupiter is exactly twice as massive as Neptune. So:

Jupiter's mass / Neptune's mass = 2.4 x 1027 kg / 1.2 x 1027 kg = 2

The correct answer to the second question is C 2.0. Jupiter's mass is twice that of Neptune's.
