e.) Did all: a, b, & c. Rotational Inertia Lab 25.) If the T' of the object placed onto the platter is increased, the hanging mass will descend: a.) slower b.) faster c.) at the same rate d.) It depends on which object's rotational inertia is being considered. 26.) How should* friction affect the experimental value for a given object's rotational inertia? your data may vary. a.) It tends to make it smaller than theory. c.) It should have not had any effect on it. d.) It depends on which object's rotational inertia is being considered. Speed of Sound 27.) Another student does this lab slightly differently from us; she defines "D" as the roundtrip distance fro the sound sensor to the other end of the tube and back. In order for this student to get a linear graph where the experiment slope should be the speed of sound, she should plot vs. time. (Assume that she still measures the time exactly as you did). a.) D/2 b.) D c.) 2D d.) 4D e.) None of these 28.) Late one night on a camping trip you see a flash of lightning, and 15 seconds later you hear the roarin thunder. The lighting must have been approximately away a.) 4 miles b.) 3 miles c.) 2 miles d.) 2 km e.) 3 kmExplanation / Answer
25.) If the 'I' of the object is increases, the hanging mass of the object will increase leading to faster descend of the object. Hence, option b is correct.
26.) Friction may vary with the experimental data as considered for a given object's rotational inertia. Hence, it depends on which object's rotational inertia is considered. Hence the option d is correct.
27.) The student describes D as the round distance, so for getting a linear graph, she should plot D/2 vs time graph. So, option a is correct.
28.) For every 5 seconds, the lighning is one mile away. So, the correct answer is 3 miles as the roaring thunder is 15 seconds after lightning.
