Is this a Good Conclusion?Is this a Good Conclusion?

The string length does make a difference The string length does make a difference in a pendulum’s swing. I tested one string in a pendulum’s swing. I tested one string length that was longer than the other. It length that was longer than the other. It was 28 and the other was 20. Galileo was was 28 and the other was 20. Galileo was right because my data backed his findings.right because my data backed his findings.
