Click For Summary
A person breathing thirty times in a minute has a frequency of 0.5 Hz, calculated by converting breaths per minute to breaths per second. The period, which is the duration of one complete breath cycle, is 2 seconds, derived from the frequency formula. Understanding that frequency is the number of cycles per second and period is the time for one cycle is crucial for these calculations. The discussion emphasizes the importance of basic conversions and the relationship between frequency and period. Overall, the calculations are straightforward once the correct units and formulas are applied.

Homework Statement



If a person breathes thirty time in a minute what is the period in seconds and the frequency in hertz of her breaths? Show your calculations...

Frequency Calculations:


Period Calculations:


Homework Equations



Frequency = 1 / period

Period = 1 / frequency

The Attempt at a Solution



This is where I am stuck...what information can i be given or any helpful tips to know where to plug in the information...please help me out ..i would really appreciate something that guide me ...

Think about what the period is, what it means. This is probably easier than you think.

What are the units of frequency? What are the units of period? That should help...
 


if u wana find the frequency, which is the number of cycles per second, find out how many breaths u take in 1 sec and put it in2 the formula, it is basic conversion that's all, it is easier that you think, just stop thinking "complicated", think basic :) hope this helps :)
 


A tiny important thing to remember is what Hertz are.
1 Hz \equiv \frac {1}{second}
 
Thread 'Chain falling out of a horizontal tube onto a table'
My attempt: Initial total M.E = PE of hanging part + PE of part of chain in the tube. I've considered the table as to be at zero of PE. PE of hanging part = ##\frac{1}{2} \frac{m}{l}gh^{2}##. PE of part in the tube = ##\frac{m}{l}(l - h)gh##. Final ME = ##\frac{1}{2}\frac{m}{l}gh^{2}## + ##\frac{1}{2}\frac{m}{l}hv^{2}##. Since Initial ME = Final ME. Therefore, ##\frac{1}{2}\frac{m}{l}hv^{2}## = ##\frac{m}{l}(l-h)gh##. Solving this gives: ## v = \sqrt{2g(l-h)}##. But the answer in the book...
