using sin r/sin i =n ( as we are moving from dense medium to less dense medium)
we get
sin r/ sin 30=1.49
rearranging we get
sin30 * 1.49= sin r
which is 0.745=sin r
rearranging, we get r=sin^-1 0.745
which is 48.2 degress (3sf)
4a)question is a simple question testing your knowledge of particle motion in fluids (Brownian motion)
any few striaght lines that are joined will do
hope it helped :D :D

Thanks... oh i was doin sin i/sin r cuz isn't dat d formula!! and yeah just wantd 2 confirm d lines :)
Plz mail me d formula sht 2... :)
Nk:
can u send me the physics formulas pls? nik_gujadhur@hotmail.com
