Answer:A) cotton
A fiber if available in trace or appropriate amount can link a suspect to a crime.Solubility is a preliminary test performed for identification of the type of fiber. In this method small amount of fiber evidence is dissolved in the suitable solvent to identify it's type. Some fibers completely get solublize in the solvent, some get partially soluble and other can only change their color or do not dissolve at all.
According to the given situation, the fiber dissolved in hydrochloric acid can be cotton. As the fibers of cotton are soft and slender and will get easily solubilize in hydrochloric acid.
Answer:
It is a force acting on the object.
Explanation:
The answer option which is true about the weight of an object is: C. It is a force acting on the object.
Weight can be defined as the force acting on a physical body or an object as a result of gravity. Also, the weight of an object is measured in Newton.
Mathematically, the weight of an object is given by the formula;
Where;
m is the mass of the object.
g is the acceleration due to gravity.
In conclusion, the weight of an object is the force acting on an object due to gravity.
Than you for posting your question here. I hope the answer helps.
The answer as to be grams (g) since you it is aske for mass. What you have for units is 1/g.
