Answer 3

its omega unit is radius /sec *

Answer 4

look velocity is given V=.5 m/s
and diameter=1/2 so radius=1/4=R
now we know that
V=Rw
w=V/r=4/2=2
again time period T=(2*PI)/w=2*pi/2=pi
so option C

Answer 5

do u get ut @sarah786

Answer 6

@sidsiddhartha - I think she changes w to rad/s , not m/s
