Question

35. The imaginary angular velocity of the earth for which
the effective acceleration due to gravity at the
equator shall be zero is equal to
(1) 1.25 x 10-3 rad/s (2) 2.50 x 10-3 rad's
(3) 3.75 x 10-3 rad/s (4) 5.0 x10-3 rad/s
[Take g = 10m/s2 for the acceleration due to gravity
if the earth were at rest and radius of earth equal
to 6400 km.)​

Answer 1

There are two types of twins – identical (monozygotic) and fraternal (dizygotic). To form identical twins, one fertilised egg (ovum) splits and develops two babies with exactly the same genetic information. ... Twins are more or less equally likely to be female or male.
