O 1s?2s?2p°3s?3p°4s23d°4ps

The first one

Explanation:

I can't read them well: it should be

** this is the expanded version

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.
