however, i prefer my previous skin more.thousand of sigh becos im really mentally exhausted to do the links again,somemore a few physics question are awaiting me now. i shall change back when im chiak pa bo shu zor. >3 it might be tomorrow, day after tomorrow or few weeks later. haha.
btw, anyone can help me to answer this?
Two sinusoidal waves in a string are defined by the functions
D
= (2.0cm) sin (20x – 30 t )
D
= (2.0cm) sin (25x – 40 t )
where y and x are in centimeters and t is in seconds.
a) What is the phase difference between these two waves at the point x = 5.0 cm at t = 2.0s ?
your help is highly appreciated! thanks! :)
