Which of the following subatomic particles gives the nucleus of an atom its mass? O both protons and neutrons
O electrons only
O neutrons only
O protons only

not clear

it forms an anion that has a larger radius. anions have a negative charge and are larger than the original atom.

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.
