By repeating the same measurement several times, the errors that can be reduced are

Options

A. determinate errors
B. instrumental erros
C. random errors
D. Systematic errors

Answer

To solve the question, we need to understand the types of errors that can occur in measurements and how repeating measurements can affect them.

### Step-by-Step Solution:

1. **Identify the Types of Errors**:
- In measurements, there are two main types of errors: systematic errors and random errors.
- Systematic errors are consistent and repeatable inaccuracies that occur due to a flaw in the measurement system.
- Random errors are caused by unpredictable fluctuations in the measurement process.

2. **Understand Random Errors**:
- Random errors can arise from various factors such as environmental changes, limitations of the measuring instrument, or human error during the measurement process.
- These errors are not consistent and can vary from one measurement to another.

3. **Effect of Repeating Measurements**:
- When the same measurement is repeated multiple times, the random errors tend to average out.
- By taking multiple readings, you can calculate an average value, which helps in minimizing the impact of random fluctuations.

4. **Conclusion**:
- Therefore, by repeating the same measurement several times, the errors that can be reduced are **random errors**.
- The correct option in this context is option 3, which states that random errors can be minimized through repeated measurements.

### Final Answer:
By repeating the same measurement several times, the errors that can be reduced are **random errors**.
