Compare the measured values of tension to the calculated values of tension. What are the possible physical experiment uncertainties for the differences between the measured and calculated?

Measured= .075N

Caculated= .079N

Velocity v = .433m/s

Mass of Cylinder m = .1118kg

Radius of Pendulum r = .265

T=mv2/r

Expert Solution

1)There is a small dependence of period on displacement that was not taken into consideration. To take amplitude into account, the accepted law, could be used.

(16)

where g is the acceleration due to gravity and ? is the angle of displacement of the pendulum from equilibrium.

2) the best-fit line does not follow the points as closely at large pendulum lengths as at smaller lengths for the data on period versus square root of pendulum length.therefore, greater care should be taken in assuring that the displacement angle is less than 10

Did the values of μ measured directly and indirectly agree? As the tension is increased, does the number of segments increase or decrease when the frequency is kept constant? As the frequency is increased, does the number of segments increase or decrease when the tension is kept constant? As the tension is increased, does the speed of the wave increase, decrease, or stay the same when the frequency is kept constant? As the frequency is increased, does the speed of...

what would happen to the values you calculated for kc in the experiment if the beer's law constant (k) value you used was high (e.g.you used 6000 M^-1 when the actual constant had a value of 5000 M^-1) ? Explain your answer.
