I see that the document contains a physics review with various exercises. Let’s go through some of the questions. Here's a breakdown of the content, and I can help solve or explain each part as needed.

### 1. Unit Conversions:
- **a.** \( 3.02 \, \text{cm} = \) \( \dots \, \text{km} \)
- **b.** \( 0.110 \, \text{ms} = \) \( \dots \, \text{s} \)
- **c.** \( 14.2 \, \text{kg} = \) \( \dots \, \text{mg} \)
- **d.** \( 1.42 \, \text{km} = \) \( \dots \, \text{mm} \)
- **e.** \( 3.02100 \, \text{m} = \) \( \dots \, \text{km} \)
- **f.** \( 7.21 \, \text{mm} = \) \( \dots \, \text{cm} \)
- **g.** \( 0.5020 \, \text{g} = \) \( \dots \, \text{mg} \)
- **h.** \( 603 \, \text{miles} = \) \( \dots \, \text{km} \) \( (1 \, \text{mile} = 1609 \, \text{m}) \)
- **i.** \( 0.213 \, \text{m}^2 = \) \( \dots \, \text{cm}^2 \)
- **j.** \( 76 \, \text{km/h} = \) \( \dots \, \text{m/s} \)

### 2. SI Units:

- **Length**: ______

### 3. Variables in an Experiment:
For the "Bunch of Objects" Lab:
- **IV (Independent Variable)**: ______
- **DV (Dependent Variable)**: ______
- **2 Constants**: ______

### 4. Identifying Variables:
- How can you identify the IV and DV of an experiment?

### 5. Data Analysis for Sales:
- Use the data to graph sales vs. temperature, find the equation, and explain the slope and intercept.

Which of these sections would you like to dive into? I can provide detailed solutions or explanations for any of these.

**Relative questions:**
1. How do you convert cm to km and vice versa?
2. What is the formula for converting speed from km/h to m/s?
3. What are the typical units for measuring mass, time, and length in the SI system?
4. What is the difference between an independent and a dependent variable in an experiment?
5. How do you interpret the slope of a graph in the context of real-world data?

**Tip:** Always double-check unit consistency during conversions to avoid calculation errors.
