please help with the two boxes that i have circled with a green color based on my data! g=9.8 m/s is the accepted value and the equation g= 4 pie etc whatever that equation is, is the measured value to find the percentage error! and please then answer the three questions on the bottom

5. Lengthen or shorten the pendulum string and repeat the above steps for as many trial as time permits. Calculate the value of g for each set of values L. and T. In each case calculate your percentage error by finding the difference between your experimental value and the standard value, 9.8 meters / sec, dividing this difference by the standard value, and multiplying by 100% Data Table: E Pendulum length (L) (meters) Trial Time for 20 Period Percent error swings t (sec) (T) (sec) (m/ sec) 0.12 m 14.775 0.74S 2. O.16 m 17.86S 0.89S 3. 0.23 m. 20.99s 1.05 S 4. 0.29 m 21.89 s 1.09s 5. 0.35m 25.01S 1.25 s 6. Related Questions: 1. Friction at the point of suspension and air resistance will tend to increase the period of the pendulum over that of the theoretical value. Would this tend to make the experimental value for g too high or too low?_ 2. Simulate a stronger gravitational force by placing a strong magnet a few centimeters below the center of the steel ball so that as the ball swings, it is pulled both by the earth's gravity and the magnet. How does this affect the period of the pendulum? How would this affect the experimental value of g ?
