One example of matter is
(1) magnetism
(3) water
(2) heat
(4) radiation

Heat

Explanation:

It is a form of energy which is not a matter.

Water is matter because it can change its form into a solid which is a matter

Magnetism is a matter because it exhibits magnetic properties that make it a matter.

Radiation is matter because it gives off high speed particles which are atoms, and all matter has atoms.

Hope this helps

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.
