The order of magnitude of height of man is

Options

A. zero
B. 1
C. -1
D. none of these

Answer

To determine the order of magnitude of the height of a man, we can follow these steps:

### Step 1: Identify the typical height of a man
The average height of a man is approximately between 1.6 meters and 1.7 meters.

### Step 2: Convert the height into scientific notation
We can express the average height in scientific notation. For example:
- 1.6 meters can be written as \( 1.6 \times 10^0 \) (since \( 10^0 = 1 \)).
- 1.7 meters can similarly be written as \( 1.7 \times 10^0 \).

### Step 3: Determine the order of magnitude
The order of magnitude is determined by the exponent of the power of ten in the scientific notation. In both cases (1.6 and 1.7), the exponent is 0.

### Step 4: Conclusion
Since both heights can be expressed in the form \( 1.6 \times 10^0 \) and \( 1.7 \times 10^0 \), the order of magnitude of the height of a man is 0.

### Final Answer
The order of magnitude of the height of a man is 0.
