Answer 1

To compare the weights of the objects on different planets, we need to use the formula for weight, which is given by:

\[ \text{Weight} = \text{mass} \times \text{gravity} \]

The gravity on different planets is approximately as follows:

• Mars: 3.71 m/s²
• Jupiter: 24.79 m/s²
• Saturn: 10.44 m/s²
• Moon: 1.62 m/s²

Now we can calculate the weight of each object:

1. Object on Mars:

   • Mass = 25 kg
   • Weight = 25 kg × 3.71 m/s² = 92.75 N (Newtons)

2. Object on Jupiter:

   • Mass = 10 kg
   • Weight = 10 kg × 24.79 m/s² = 247.9 N

3. Object on Saturn:

   • Mass = 15 kg
   • Weight = 15 kg × 10.44 m/s² = 156.6 N

4. Object on the Moon:

   • Mass = 50 kg
   • Weight = 50 kg × 1.62 m/s² = 81 N

Now, we can summarize the weights calculated:

• Object on the Moon: 81 N
• Object on Mars: 92.75 N
• Object on Saturn: 156.6 N
• Object on Jupiter: 247.9 N

Now, we can arrange the objects from smallest weight to greatest weight:

1. An object with a mass of 50 kg on the Moon (81 N)
2. An object with a mass of 25 kg on Mars (92.75 N)
3. An object with a mass of 15 kg on Saturn (156.6 N)
4. An object with a mass of 10 kg on Jupiter (247.9 N)

So the order from smallest weight to greatest weight is:

1. Object on the Moon
2. Object on Mars
3. Object on Saturn
4. Object on Jupiter
