Unformatted text preview: 980.102.004 cm/s 2 Final Questions 1. Yes, we found agreement within our estimated uncertainity because we found values of g to be 9.8 9.80m/s2 which is extremely close to the actual value of 9.80102m/s2. 2. Yes because although the weights differed, the calculated g values were extremely close. Even the the two bobs was close. This proves that the mass of the bobs is negligible in the experiment. 3. The period length depends on the length of the string only. The mass does not affect the string leng period is independent of the mass. # periods 6 8 10 13 # periods 7 8 10 13 u &lt;t&gt; (s) u &lt;t&gt; (s) 81m/s2 and e &lt;T&gt; s between gth therefor the...
