Here are the answers to the quiz questions:

**Question 1: A person weighing 600 N gets on an elevator. The elevator lifts the person 6 m. How much power was used?**
- To calculate power, we first find work done using the formula:
\[ \text{Work} = \text{Force} \times \text{Distance} = 600 \, \text{N} \times 6 \, \text{m} = 3600 \, \text{J} \]

Power is work done over time. However, since time is not provided, we cannot determine power exactly. But the work done is **3,600 J** (making this the best choice).

**Correct Answer: 3,600 J**

**Question 2: A wheelbarrow can be considered as a compound machine because it has which of the follow two simple machines?**
- A wheelbarrow consists of a **wheel and axle** (the wheel) and a **lever** (the handles act as a lever to lift the load).

**Correct Answer: wheel and axle and lever**

**Question 3: If a man moves a large box that weighs 10 Newtons 20 meters, how much work was done?**
- Work done is calculated using:
\[ \text{Work} = \text{Force} \times \text{Distance} = 10 \, \text{N} \times 20 \, \text{m} = 200 \, \text{J} \]

**Correct Answer: 200 J**

**Question 4: Which is the correct definition of a simple machine?**
- A simple machine is a device that helps to make work easier.

**Correct Answer: a device that makes work easier**

---

**Question 5: What is the formula to calculate the work done on an object?**
- The formula for calculating work done is:
\[ \text{Work} = \text{Force} \times \text{Distance} \]

**Correct Answer: force x distance**
