Question

DATE: 3/29/2018 Huygens was the first to use a pendulum to determine a value for (G) Be creative!, construct a pendulum by attaching a mass to a string.On the back draw a picture of your pendulum. Measure the mass and the length of a string. All measurements must be in metric with the correct significant digits, Measure the time it takes for 10 complete swings. Do this activity several times ( at least 3) and the average time for one swing. Calculate the value of G from the following equation: G-HPL EX. VALUC Record all data with correct units and significant digits MASS OF OBJECT-24Zg LENGTH OF STRING: _SHm TIME FOR COMPLETE SWINGS: IS:3(o (S:40 |r,y · AVERAGE TIME FOR 10 SWINGS: IStL TIME FOR ONE SWING: SL SHOW WORK FOR THE VALUE OF G: 6ERROR FOR G 4(3.14 5gtm) I.545 1-9.6 .Si RUBRIC: CONSTRUCT OF PENDULUM: 10 PTS DRAWING DATA CALCULATIONS TOTAL: 10 PTS 6PTS

Explanation / Answer

I have checked your all calculations minutely for several times. But i could not find any mistakes except in %ERROR FOR G.

Your value of %ERROR FOR G is absolutely correct but you have missed the sign, which must be negative.

Here negative sign indicates that your approaximate value is less than the exact value.

So, %ERROR FOR G = -1.02%
