Homework Answers
a. From the figure displayed, it can be inferred that the beam has both the ends hinged . The position of the motor is little eccentric and thus with increase in angular speed, the vibration amplitude of the beam increases linearly. So a graph of amplitude vs angular speed will result in a linear ( straight line)
b. In order to reduce the vibration amplitude, two things can be done
1. Repositioning the motor to the exact center of the beam will make it to be placed in the nodal point and thus vibration amplitude will be reduced.
2. A support can be provided directly below the motor to make that position of the beam as a mode where vibration amplitude will be zero

It's a weak acid strong base titration
Experiment 4: Identification of an unknown acid by titration Page 2 of 15 Background In this experiment, you will use both qualitative and quantitative properties to determine an unknown acid's identity and concentration. To do this analysis, you will perform a titration of your unknown acid sample-specifically a potentiometric titration where you use a pH meter and record pH values during the titration, combined with a visual titration using a color indi- cator...
