The is used to identify a mixture as a colloid.

The filter is used to identify a mixture as a colloid.

Explanation:

Colloids are those substances that, being in a liquid, slowly disperses. A colloid is made up of two phases: a dispersing phase and a dispersed phase. By dispersing little by little, the filters are used for their separation, for example, being in a liquid, the colloidal particles are large enough to be blocked by the filter and thus separate them.

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.
