Why could bohr’s model be called a planetary model of the atom?

The Bohr Model of the atom is very much like our solar system, with a sun as the center like the nucleus of the atom and the planets locked in defined orbits like the electrons locked in orbits around the nucleus.

b. examine and describe cells

weight of any object is given by

w = m*g

where m is mass of the object and g is the acceleration due to gravity.

for earth the value of g is 9.8 m/s^2 so

w=117.6 n m=12 g=?

117.6=12g => g=9.8 m/s^2

which is the force of gravity on earth.
