Choose the correct option for each question. There is only one correct response for each question.
A ball traveled 10cm on surface x and 50cm on surface y. Identify this type of surfaces

Options

A. x-sandy floor, y-sandy ground
B. x-sandy floor, y-cemented ground
C. x-cemented floor, y-sandy ground
D. x-cemented floor, y-cemented ground

Answer

To solve the question regarding the type of surfaces based on the distance a ball traveled on each, we can follow these steps:

### Step-by-Step Solution:

1. **Understand the Problem**: The ball travels 10 cm on surface X and 50 cm on surface Y. We need to determine the nature of these surfaces based on the distances traveled.

2. **Analyze the Distances**: The ball travels a shorter distance on surface X (10 cm) compared to surface Y (50 cm). This indicates that the ball encounters more resistance or friction on surface X than on surface Y.

3. **Infer Surface Characteristics**:
- Since the ball travels less on surface X, we can conclude that surface X is rougher.
- Conversely, since the ball travels more on surface Y, it suggests that surface Y is smoother.

4. **Identify Surface Types**:
- Surface X is rough (e.g., sandy floor).
- Surface Y is smooth (e.g., cemented floor).

5. **Evaluate the Options**:
- **Option 1**: X is sandy floor and Y is cemented floor. This option is consistent with our analysis since sandy floors are rough and cemented floors are smooth.
- **Option 2**: X is sandy floor and Y is cemented floor. This option also aligns with our findings.

6. **Select the Correct Option**: Since both options describe the same scenario, we confirm that the correct identification is:
- Surface X is rough (sandy floor).
- Surface Y is smooth (cemented floor).

### Conclusion:
The correct option is that surface X is rough and surface Y is smooth.
