Example of a man-made object that has been changed by weathering

A man-made object that has been changed by weathering is the pyramids. The pyramids in Egypt have weathered slowly because of the dryness of the desert, but they have indeed weathered throughout the years.

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.
