To express concentration as a percentage, you simply divide the quantity of the substance by the total mixture mass, and then multiply by 100. For instance, if you want to calculate the percentage of P in the sample, the calculation is as follows:
%P = 7.5 g/100 g * 100 = 7.5%
43.62m
Clarification:
Given details:
Energy = 8550J
Mass of bell = 20kg
Unknown:
Height of the bell =?
Solution:
This bell possesses potential energy, which signifies energy at rest due to its positional context.
Potential energy = m g h
where m denotes the mass of the object
g indicates gravity's acceleration
and h stands for the height of the object
Here, we need to isolate for h.
g = 9.8m/s²
Insert the variables;
8550 = 20 x 9.8 x h
As a result, h = 43.62m
