Answer:
x = 2 meters.
Explanation:
Let the position (distance) of fulcrum to the load be x.
Given the following data;
Load = 40 kg
Effort (force) = 40 Newton
Effort arm = 4 - x
To find the position of the fulcrum, we would use the expression;
Effort * effort arm = load * load arm
40 * (4 - x) = 40 * x
160 - 40x = 40x
160 = 40x + 40x
160 = 80x
x = 160/80
x = 2 meters
Therefore, the position (distance) of fulcrum to the load is 2 meters.
The rock had to have undergone chemical weathering due to its change in mineralogical and chemical composition of the rock.
Or
Chemical weathering is when the acid from rain starts to burn through rocks and damage them
Not sure if this is what your looking for, but hope it helps. Nitrogen gas can be changed into nitrogen compound through nitrogen fixation, which is the conversion of nitrogen gas to ammonia, that are absorbed by the plant to make protein. Another way is through animals eating plants and obtaining nitrogen, which is later released, by decomposes, when the organism dies.
