How does that work? If the fundamental frequency is 147 Hz then (147/4) equals the length? =36.75 this is not what I found... Do I divide by four then?

A clarinet can be treated as a resonant tube with one closed end. The fundamental frequency is 147 Hz. I was able to figure out the length of the clarinet: it is .583 m BUt the question is to calculate the frequencies of the first three overtones. Would the overtone equatinos used to...

Thanks for your help!

I am guessing that as the sonic jets take off they break the sound barrier and it will break the glass of people's houses once they take off. Also that it is too noisy But how do I discuss wave properties?

Teachers Question: Why are the air bases of super sonic jets usually located far away from cities? Your response should discuss wave properties. I don't know what to answer. I have searched everywhere for it. Please help me!

A girl drops a stone into a mineshaft 122.5 m deep. How soon after she drops the stone does she hear it hit the bottom? What formula do I use?

Stupid question, not sure what to say... In a science fiction movie, when a spaceship explodes, the vibrations form the sound nearly destroy a nearby spaceship. If you were the science consultant for the movie, what would your advice be for the producer? Anyhelp would be greatfully accepted!

Am I right with the whole lengthening thing?

I am guessing that the metal rod expands when the room is hotter and "shrinks" when the room is colder. If the length is a dependent factor, wouldn't the period affect it because the rod lengthens and condenses?

How does temperature affect grandfather clocks? A metal rod pendulum is inside of the clock. I have a question regarding this. If an expirement happened where 3 clocks were sent to the same time. ONe was put in a cold room, one in a hot, and one in a room temperature room. What would the...

part A askes Which variable(s) affect the period of the pendulum

I don't know

A screw is put into the top of a cocnut and a long string is tied to the cocounut to make a simple penullum. A small hole is punched into the bottom of the coconut and the pendulum is made to oscillate. The cocnut milk flows gradually out through the hole. It is observed that the period...

I am teaching myself Physics 20. the question is basically that you tie a cococnut to a string and put a hole of the cocnut at the bottom so that the milk flows gradually out. The question is asking what variables affect the period of the penduallum

Could someone please explian the motion of a pendulum for me? When the weight is heavier is the pendulum slower or fast than when the weight is less?
