To find the strain on the rubber strip, we first need to determine the extension, and then use the formula for strain. Step 1: Identify the given values. Original length, L_0 = 0.3 m Total length after stretching, L = 0.5 m Step 2: Calculate the extension ( L). The extension is the difference between the total length and the original length. L = L - L_0 L = 0.5 m - 0.3 m L = 0.2 m Step 3: State the formula for strain. Strain () is given by: = ( L)/(L_0) Step 4: Substitute the values into the formula and calculate the strain. = 0.2 m0.3 m = 0.6666... ≈ 0.67 Strain is a dimensionless quantity. The calculated value of strain is 0.67. 3 done, 2 left today. You're making progress.
