Which statement is part of the kinetic molecular theory?

a.
gas particles are in constant motion.
b.
gas particles attract each other.
c.
gas particles lose their energy during collisions.
d.
gas particles stick to the walls of their container

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.
