Hello, can you please help me with this. Based on the first page can you please help me fill out table 2 completely ñ. Thanks (:
**Pendulum Experiment: Determining the Period**

**Objective:**
Investigate if the mass of a pendulum affects its period.

**Pendulum Period Formula:**
\[ T = 2\pi \sqrt{\frac{L}{g}} \]

Where:
- \( T \) = period (in seconds)
- \( L \) = length of the pendulum (in meters)
- \( g \) = acceleration due to gravity (9.8 m/s²)

**Laboratory Report**

1. **Free Body Diagram:**
   - A pendulum is depicted with forces:
     - \( T \) = Tension
     - \( RF \) = Restoring Force
     - \( W \) = Weight

**Data and Calculations Table 1:**

| Mass (kg) | T1(s) | T2(s) | T3(s) | T\(_{\text{average}}\)(s) | % Error |
|-----------|-------|-------|-------|------------------|---------|
| 0.0500    | 1.9175| 1.9144| 1.9138| 1.9153           | -4.24   |
| 0.1000    | 1.9293| 1.9911| 1.9278| 1.9494           | 2.53    |
| 0.2000    | 1.9261| 1.9376| 1.9305| 1.9314           | -3.43   |

- Length \( L \) = 87 cm = 0.87 m

2. **Calculate the period \( T \) for \( L \):**
   - \( T_{\text{standard}} = 1.8711 \) sec

3. **% Error Calculation:**
   \[
   \% \text{error} = \frac{\left| T_{\text{average}} - T_{\text{standard}} \right|}{T_{\text{standard}}} \times 100 = 3.255\%
   \]

5. **Analysis:**
   - **Does the period depend on mass?**
     - The period is only a function of \( L \) and \( g \). There is no dependence of mass on the period.

**Calculation Details:**
- \( T_{\text{average

6. **Graphing Period Squared vs. Pendulum Length:**
   - Make a graph of period squared (on Y-axis) versus length (on X-axis) of the pendulum.
   - This graph is supposed to display a straight line. Explain why.

7. **Drawing the Best Fit Line:**
   - Draw the best fit line without hitting any data points.
   - Use two points on the line that are not data points to calculate its slope.
   - Clearly show calculations and include units.

8. **Calculating Gravitational Acceleration (g):**
   - Calculate g from the slope.
   - Explain how the slope is related to g.

9. **Determining the Percentage Error:**
   - Calculate the percentage error between the measured g and the standard value of g = 9.80 m/s².
   - Use the formula:  
     % error = | Measured g - g_standard | / g_standard × 100
