1) You are a new employee at the Cut-Rate Cuckoo Clock company. The boss asks you what would happen to the frequency of the angular simple harmonic motion of the balance wheel if it had the same density and the same coil spring (thus the same torsion constant), but all the balance wheel...

If you guys can check the math on these last 3 questions I would be very greatful. Sorry to throw this many questions at you but I've been doing physics 3 days straight now reviewing for my final tomorrow. Any help would be awsome. :approve: 1. How much heat energy is required to convert a...

Thanks for the clarification on #13 doc. Thanks for checking my answers Janitor I really appreciate your time and for some reasons understand your explanatiosn better than my professors.

Hi, these are off of my final review sheet. Theres a lot of them but I think most my answers are correct :smile::smile: * = my answer. 1. Kinetic Theory accounts for the increase in pressure as a confined gas is heated by what? *An increase in particle motion, more violent and...

Thanks for helping Janitor. 1) Since the mass is greater on weekdays the period of oscillation with be greater. 3) Thanks for the tip about beat frequency! The formula is Fb = |F1-F2| Interference will alter the sound. Fb = |100kHz-102kHz| = 2kHz the human ear can hear at 2kHz...

well i think i was exaggerating a bit when I said he was a dickhead. Hes a great guy but very picky. :cool: When did I say or even imply that I want better marks even though I am getting it wrong?

for #3) Can I do y' = (3x^4-9x^3+12x^2+3x) / (x^3+1)^2 y' = 3x(x^3-3x^2+4x+1) / (x^3+1)^2 ? for #5) Can i do h'(x) = 1/2(3+2x)^(-1/2)(2) h'(x) = (3+2x)^(-1/2) ? Im not sure about 10 and 12 it seems like something could be done or? TRhanks again guys i really appreciate it

thansk guys. Yea i tend to leave out the part where u square the denominator in the quotient rule. Thanks for the head up!

Please double check my work ! Hi, I basically did out all the poroblems. I just need someone to double check whether I made any mistakes in the answers or procedures. (My prof is a real dickhead and marks down for the smallest mistake) Also can I simplify any answers, just like obvious stuff...

3) Sorry! **A human ear cannot hear sound at a frequency of 100 kHz or a sound at 102 kHz. But, if you walk into a room in which two sources are emitting sound at 100 kHz and at 102khz, you'll hear sound. Explain why this is possible. *Has to do with the two frequencies combining? (No idea...

Some chapter review problems in the back of the book I was having trouble with. Any help is appreciated. (Not asking for answers but directions and formulas explanations if possible) Thank you! 1) The Empire State Building in New York City oscillates in the wind with a period of 8 seconds. Do...

thanks for the help!

consider function f(x) = 1/3X^3 - 1/2^2 - 6x + 4 maximum is positive infinity and minimum is negative infiniti correct? Thank you!

Define derivative from 3 perspectives? I might be off but I only came up with slope and rate of change? Is this correct? Whats the 3rd one? Thanks for any help in advance !
