An angstrom is equal to :

Options

A. `10^(-7)` m
B. `10^(-8)` m
C. `10^(-9)` m
D. `10^(-10)` m

Explanation

### Step-by-Step Solution:

1. **Understanding the Unit**: An angstrom (Å) is a unit of length that is typically used to measure very small distances, such as atomic and molecular scales.

2. **Identifying the Conversion**: We need to determine how many angstroms are in one meter. It is known that:
- 1 meter = 10^10 angstroms.

3. **Calculating the Value of One Angstrom**: To find the value of 1 angstrom in meters, we take the reciprocal of the number of angstroms in a meter:
- 1 angstrom = 1 meter / 10^10 angstroms = 10^-10 meters.

4. **Comparing with Given Options**: Now, we compare our calculated value (10^-10 meters) with the provided options:
- Option 1: 10^-7 meters
- Option 2: 10^-8 meters
- Option 3: 10^-9 meters
- Option 4: 10^-5 meters

5. **Selecting the Correct Answer**: Since we calculated that 1 angstrom = 10^-10 meters, none of the options provided match this value. However, it is important to note that the correct conversion is indeed 10^-10 meters.

### Final Answer:
1 angstrom is equal to 10^-10 meters.
