Sure, let's tackle the given questions step by step:
Step-by-Step Solution:
37. Ordering the planets from heaviest to lightest:
To arrange the planets by their masses, we need to compare their masses given in the question:
- Jupiter: 1.9 × 10^27 kg
- Mars: 6.42 × 10^23 kg
- Earth: 5.97 × 10^24 kg
- Venus: 4.87 × 10^24 kg
- Mercury: 3.3 × 10^23 kg
Now, let's arrange them from heaviest to lightest:
1. Jupiter: 1.9 × 10^27 kg (heaviest)
2. Earth: 5.97 × 10^24 kg
3. Venus: 4.87 × 10^24 kg
4. Mars: 6.42 × 10^23 kg
5. Mercury: 3.3 × 10^23 kg (lightest)
So the list of planets from heaviest to lightest is:
Jupiter, Earth, Venus, Mars, Mercury
38. Calculating the mass of Saturn:
The question states that Saturn's mass is about 100 times the mass of Earth. We are given Earth's mass as:
- Earth: 5.97 × 10^24 kg
To find the mass of Saturn, we multiply Earth's mass by 100:
[tex]\[
\text{mass of Saturn} = 100 \times \text{mass of Earth} = 100 \times 5.97 \times 10^{24} \text{ kg}
\][/tex]
Calculating that we get:
[tex]\[
\text{mass of Saturn} = 5.97 \times 10^{26} \text{ kg}
\][/tex]
So, the mass of Saturn is approximately [tex]\(5.97 \times 10^{26}\)[/tex] kg.
Summary:
37. Planets ordered from heaviest to lightest:
Jupiter, Earth, Venus, Mars, Mercury
38. The mass of Saturn:
[tex]\(5.97 \times 10^{26}\)[/tex] kg
