An object oscillates 50 times in one second. What should be its frequency ?

Options

A. 0.2 Hz
B. 0.02 Hz
C. 0.002 Hz
D. 50 Hz

Explanation

To find the frequency of an object that oscillates 50 times in one second, we can follow these steps:

### Step-by-Step Solution:

1. **Identify the Number of Oscillations**:
The problem states that the object oscillates 50 times. Therefore, the number of oscillations (N) is:
\[ N = 50 \text{ oscillations} \]

2. **Identify the Time Period**:
The time taken for these oscillations is given as one second. Thus, the time (T) is:
\[ T = 1 \text{ second} \]

3. **Use the Formula for Frequency**:
Frequency (f) is defined as the number of oscillations per unit time. The formula for frequency is:
\[ f = \frac{N}{T} \]
where:
- \( f \) is the frequency,
- \( N \) is the number of oscillations,
- \( T \) is the time period.

4. **Substitute the Values into the Formula**:
Now we can substitute the values we identified into the formula:
\[ f = \frac{50 \text{ oscillations}}{1 \text{ second}} = 50 \text{ Hz} \]

5. **Conclusion**:
Therefore, the frequency of the object is:
\[ f = 50 \text{ Hz} \]

### Final Answer:
The frequency of the object is **50 Hz**.
