Title: physics help!
Post by: nonelee on June 01, 2009, 05:35:51 am

which one is the loudness? amplitude or frequency?
if one of them stands for the loudness, then what does the other one stand for?

PLEASE HELP ME.
and anyone taking coordinated science doubled award?

amplitude is for loudness

frequency for pitch
directly proportional

hope that helped.. :)

(sry, i haven't taken co-ordinated science)

see PF
pitch frequency (PARIS FRANCE)
loudness amplitude(LOS ANGELES)

remember like this !!! it really helps !

lsn i will tell u smthng that will help u memorize dem wen u scream AAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAA u open ur mouth so its da amplitude
LOUDNESS depends on AMPLITUDE
and
PITCH depends on da other which is frequency
did this help ;D

Hey everyone!
Can someone help me with question 3 (b) June 07?
Why can't GPE be converted to kinetic energy and how does it get converted to heat?

lol...this is a wierd question

but in these types of questions
be smart and answer all the possibilites
they will ignore the ones not required

mention everything sound, heat, kinetic energ...
good luck
