WHY THIS QUESTION ANSWERS C
Earthquakes at two places A and B were measured by a seismograph which recorded the magnitude as 2 and 4. The magnitude of tremors and the destructive energy at A and B can be compared as
A Tremors at B are two times those at place A
B Tremors at B are four times those at place A
C Tremors at B are 100 times those at place A
D Tremors at B are 1000 times those at place A.
pls tell how to calculate
Kepler's third law states that square of period of
revolution (T) of a planet around the sun is proportional
to third power of average distance r between the sun
and the planet i.e. T2 = Kr3 (here K is constant). If the
masses of sun and planet are M and m respectively then
as per Newton's law of gravitation, force of attraction
between them is F = GMm/r2, here G is gravitational
The relation between G and K is described as
A K = G
B K = 1/G
C GK = 4π2
D GMK = 4π2

The given figure shows a typical animal cell with its
parts being labelled as 'a - j'. Identify the labelled
parts and select the incorrect option regarding it.
A The organelles e, h, g and i are membrane-bound organelles which function in close coordination with one another.
B 'f' organelle is responsible for the synthesis of fats inside the cells and it stores Ca2+ for release during muscle contraction.
C a and b have selective permeability i.e., they allow only selected substances to pass inwardly.
D 'j' is the site for protein synthesis. It allows hereditary message from 'd' to get translated into proteins.
