While visiting the albert michelson exhibit at clark university, you notice that a chandelier (which looks remarkably like a simple pendulum) swings back and forth in the breeze once every t = 6.2 seconds.
randomized variablest = 6.2 seconds
(a) calculate the frequency of oscillation (in hertz) of the chandelier.
(b) calculate the angular frequency ω of the chandelier in radians/second. sig. gif? tid=2n74-08-dd-43-8d37-13518no attempt no attempt25% part (c) determine the length l in meters of the chandelier. sig. gif? tid=2n74-08-dd-43-8d37-13518no attempt no attempt25% part (d) that evening, while hanging out in j. j. thompson’s house o’ blues, you notice that (coincidentally) there is a chandelier identical in every way to the one at the michelson exhibit except this one swings back and forth 0.11 seconds slower, so the period is t + 0.11 seconds. determine the acceleration due to gravity in m/s2 at the club.

a) 0,1613 Hz

b) 1,01342 rad/sec

c) 9.5422 m

d)

Explanation:

In the Albert Michelson exhibit at Clark University, we know the period of oscillation of the chandelier is T = 6.2 seconds

The chandelier will be modeled as a simple pendulum

a) Since the frequency is the reciprocal of the period, we have

b) The angular frequency is computed as

c) The period of a simple pendulum is given by

Where L is its length and g is the local acceleration of gravity (assumed 9.8 for this part)

We want to know the length of the pendulum, so we isolate L

d) While hanging out in J.J. Thompson’s House O’ Blues, the new period is 6.2+0.11=6.32 sec. Since the chandelier is the very same (same length), we can assume the gravity is slightly different. We use again the formula for T, but now we'll isolate g as follows

Which results  

i. like it i'm gonna edit it tomorrow

there is no correct list among the choices you've provided.

the list might look something like this:

-- baby human

-- piccolo

-- flute

-- soprano singer

-- trumpet

-- tenor singer

-- trombone

-- baritone singer

-- baritone horn

-- bass singer

-- tuba

since i had to make up the list myself, i made it easy on myself, and i didn't try to shuffle the string instruments and woodwinds into it too.
