What’s the correct option?

Transcribed Image Text:### Educational Content: Analyzing Machine Efficiency in Moving Objects
#### Problem Statement:
Four machines (A-D) push four identical heavy boxes 100 meters along a track. According to the graph, which machine pushed with the least force?
#### Options:
- ⬤ Machine D
- ○ Machine C
- ○ Machine B
- ○ Machine A
- ○ All pushed with the same force.
#### Graph Explanation:
The graph provided has two axes:
- The horizontal axis represents **Power (W)**.
- The vertical axis represents **Velocity (m/s)**.
The graph plots the relationships between power and velocity for the four machines (A, B, C, and D).
- **Machine A**: Represented by the line with the steepest ascent in velocity as power increases.
- **Machine B**: Represented by the second line with a less steep slope compared to Machine A.
- **Machine C**: Represented by the third line with an even more gradual slope.
- **Machine D**: Represented by the line with the least steep slope out of all, showing the slowest increase in velocity as power increases.
#### Interpretation:
To determine which machine pushed with the least force, you need to understand that:
- Force \( F \) can be derived from the relation \( Power = Force \times Velocity \).
- For machines pushing the same distance, the one with the least steep graph experiences less force for a given power.
#### Conclusion:
Based on the graph, **Machine D** shows the least increase in velocity for the given power, indicating that it pushed with the least force.
**Answer: Machine D**
