Which actions would increase the rate at which salt dissolves in water

Grinding, stirring and heating

Explanation:

A fine or crushed salt will dissolves faster in water because it has a lesser surface area which is one of the determinants of how fast a reaction rate can be.

Stirring also increases the speed at which salt particles come in contact with the water molecules.

Heating salt solution increases the speed at which salt particles come in contact with the water molecules

i believe that it is a exoplanet

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.
