A point P lies on x-axis and another point Q lies on y-axis.
Write the ordinate of the point P.

Answer

To solve the question, we need to determine the ordinate of point P, which lies on the x-axis.

### Step-by-Step Solution:

1. **Understanding the Axes**:
- The x-axis is the horizontal line in the coordinate plane where the y-coordinate (ordinate) is always zero.
- The y-axis is the vertical line where the x-coordinate (abscissa) is always zero.

2. **Identifying Point P**:
- Since point P lies on the x-axis, we can denote its coordinates as \( P(x, 0) \), where \( x \) can be any real number.

3. **Defining Ordinate**:
- The ordinate of a point is defined as its y-coordinate. For any point on the x-axis, the y-coordinate is always zero.

4. **Conclusion**:
- Therefore, the ordinate of point P, which lies on the x-axis, is \( 0 \).

### Final Answer:
The ordinate of point P is \( 0 \).
