Polluted water. The growing crops and climate variability change. Basically the farming
Explanation:
The force of gravity acting on an object is given by :
W = F = mg
Where W is the weight of an object
The force of gravity on house is 300,000 N. The force of gravity pulling down on your house would be exactly twice as much if your house has twice as much as mass because force of gravity is directly depends on mass.
Density= mass/volume
= 100/25
density = 4g/ml
