WHAT IS THE IUPAC NAME FOR CH3COCH2CH2CHO
|
|
|
|
 cos2x /  (1+sin2x)
|
|
|
|
N1<N2
N=-Mg
as the hieght increases g decreases
g1<g2
So N1<N2
PLS INFORM ME IF ITS WRONG

|
maximum extension of the spring will be 2.23cm
if it its wrong pls notify me

D is the distance between two towns
velocity of both the buses is assumed to be same
relative velocity of busses,
v-20 km/hr in the direction of cyclist
v+20 km/hr in the opp direction
applying in distance/velocity is time
we get the to equations
we get distance D & velocity
then we can find the time period of bus

pls notify me if its wrong

i am also getting the same answer 10/3r

D/v-20=18/60 -- i
D/v+20=6/60 --ii
solving for v & D
we get D=4km & v=20 km/hr
t=D/v
=1/5hrs
=12min (c)
pls inform me it its wrong

1/R=1/R1+1/R2
1/ * /a=1/  1*/a+1/2*/a
1/=1/1+1/2
=1+2/12
