Answer:
La densidad (más precisamente, la densidad de masa volumétrica; también conocida como masa específica), de una sustancia es su masa por unidad de volumen. El símbolo más utilizado para la densidad es la letra griega en minúsculas rho), aunque también se puede utilizar la letra latina D. Matemáticamente, la densidad se define como masa dividida por volumen: .m/V donde es la densidad, m es la masa y V es el volumen. En algunos casos (por ejemplo, en la industria del petróleo y el gas de los Estados Unidos), la densidad se define libremente como su peso por volumen unitario, aunque esto es científicamente inexacto – esta cantidad se llama más específicamente peso específico.
Explanation:
If you have 12 atoms of hydrogen before a chemical reaction, the number of hydrogen atoms that will be present after the chemical reaction is 12 atoms.
The Law of Conservation of Mass (LOCOM) states that mass is neither created nor destroyed before and after any chemical reaction.
According to the Law of Conservation of Mass (LOCOM), a balanced chemical equation requires that the number of atoms on the reactant side must be equal to the number of atoms on the product side of any chemical reaction.
In this context, a chemical reaction having 12 atoms of hydrogen as reactants at the beginning, should also produce a total of 12 atoms of hydrogen as products at the end of the chemical reaction.
Answer:
q = 0.036 C
Explanation:
Given that,
Current passes through a defibrillator, I = 18 A
Time, t = 2 ms
We need to find the charge moved during this time. We know that,
Electric current = charge/time
Put all the values,
So, 0.036 C of charge moves during this time.
He is discussing Bargaining Power of Buyers competitive force.
What do you understand by leverage?
The employment of various financial instruments or borrowed cash, or leverage, is an investing strategy that aims to improve an investment's potential return. The level of debt a company utilizes to finance its assets is another definition of leverage.
It offers a range of funding options so that the company can reach its desired earnings. Leverage is a crucial investing strategy because it enables businesses to establish a ceiling for the growth of their operations.
Leverage can be used, for instance, to support financially a new business. Purchasing fixed assets or borrowing money in the form of a loan from another business or person can serve as examples of leverage.

Answer:
Air
Explanation:
Matter exists in three states namely; solid, liquid and gas. These three states contain molecules/particles that behave differently from one another. The particles of gas are scattered in such a way that they move randomly in a fast motion. This causes the ability of gas particles to diffuse in an open space i.e. spread quickly
In the options of materials given in this question, AIR represents a gaseous substance, hence, it is made up of particles that move rapidly in a random manner. This will cause it to spread out (diffuse) to completely fill a larger container it is placed in.
