Please help! I don't understand how to complete the rest of the table.

To convert g to kg, use the conversion factor: 1 kg = 1000 9. To convert cm to m, use the conversion factor: 1 m = 100 cm. 9 = 9.81 m/s"', the acceleration due to gravity. 22 Visually determine the sign of the torque. Note: Torque is positive when it tends to cause counter-clockwise rotation about the pivot point and negative when it tends to cause clockwise rotation about the pivot point. Part 1: Torque About the Center of Mass 1 Gather the supplies necessary for the experiment, including five washers, string, wooden ruler, digital scale, protractor, safety goggles, and a wall hook attached to a suitable location to hang a ruler. Note: Instead of a wall hook, an over-the-door coat hook, shower curtain rod, or balcony railing are possible locations that could be used to hang the ruler. The following exercise will work best if a solid surface, such as a wall or door, is directly behind the hook. 2 Put on your safety goggles. Note: \\ew the video, Using the Digital Scale, before continuing the procedures. If needed, a descriptive text transcrip_t is available. Using the Digital Scale I L? This video shows how to use a digital scale 3 Use the digital scale to measure the mass of five washers and record to 0.01 g in Data Table 1. 4 Calculate the average mass of each washer and record to 0.01 g in Data Table 1. 5 Use the digital scale to measure the mass of the ruler and record to 0.01 g in Data Table 1. 6 Cut two lengths of string to 20 cm and one length of 60 cm from the 4 m length of string. 7 Tie one end of the 60 cm length of string to the wall hook or other support. 8 Tie the other end of the 60 cm string around the ruler near its center so that the centimeter scale is on top. 9 Adjust the location of the string along the ruler until the ruler hangs horizontally from the string. 10 Use the protractor to verify that the string makes a 90 angle with the ruler as shown in Figure 8. 23 Record your calculated T1 including the sign in Data Table 2. 24 Calculate the mass of one washer using the average mass in Data Table 1 and record as mg in Data Table. 25 Record the ruler position x2 for m2 found in step 17 to 0.01 cm in Data Table 3. 26 Repeat steps 19-23 for mass m2 and record the results in Data Table 3. 27 Calculate the theoretical torque, Tammy, due to the weight of mass m2 using the equilibrium equation: ZT=0=T1+72 T2,theory = _71 28 Record your calculated 12mm\11 Secure the string to the ruler so that the string is vertical and not twisted front to back or top to bottom. See Figure 9. Figure 9. String taped to ruler such that the top and bottom of the string align in a straight, vertical line. 12 Record the position of the string on the ruler as the center of mass of the ruler to 0.01 cm in Data Table 2. Note: This position will now be known as x0, the pivot point location for Part 1. 13 Calculate the mass of two washers using the average mass recorded in Data Table 1 and record as m in Data Table 2. 14 Tie two washers (m1) to one end of one short string, attach the other end of the string to the ruler at the 10.00 cm mark, and record as the ruler position x1 to 0.01 cm in Data Table 2. 15 Secure the string with tape. Note: Hold the ruler level until completing step 17. 16 Tie one washer to one end of the second short string (m2) and attach the free end of the string to the ruler on the right of the center of mass
