Derived units are units built up from SI base units. It has been found that relatively few base units are required.
Typical derived units are m/sec (metres per second), sometimes written m.sec-1 for speed and joules/sec, sometimes written joules.sec-1 for power. Although the latter unit is a derived unit, it has its own name, the watt, for convenience. (Nonetheless, the people who govern the business of defining units have been scrupulous in defining it in terms of base units because it's possible.) New base units are defined when phenomena are encountered which simply cannot be measured in terms of existing base units or units derived from them.
A SI base unit is a direct measurement unit for a physical entity, an example of which is kilogram. A derived unit is determined by a physical equation with the base units, an example of which is meter per second.
There are several SI base units, and many more derived units, which are combinations of other units. For example, meter and second are base units, meter/second (for speed or velocity) is a derived unit. For more details, see these links:

Both can be a measurement unit for length, mass and time.
Not have a proper answere
This completely depends on the compound it is forming. If the compound is NaCl for example, this is an example of ionic bonding (the difference between the larger electronegativity and higher electronegativity is above 1.9). If it's somthing like FCl for example, the bond is covalent (the difference between the larger electronegativity and higher electronegativity is below 1.9).
Some kinds have a different amount of ingredients. Some have more moisterizer or less for example. Like dove.
The difference is not very big, even quite formally, I'd say.Alkali are hydroxidesBase is a substance capable of reaction with protons (H+ ions) donated by acids.So:All alkali's in solution are bases,but not all bases are alkali: for example NH3 basic but not a hydroxide of a metal ion.
Whilst in theory, both are a gas given off by an object. A fume is commonly associated with noticeable gas excretion, for example: a chemical reaction. An odour is associated with a smell, for example: flatulence.
Mefenamic acid is a painkiller. Tranexamic acid is a drug that lessens bleeding (for example, if you have heavy periods or have had a tooth extraction).

An example is where someone asks you what something is you show them instead of tell them. A definition is where you explain what something is.
Difference between define and cons is that, con is disadvantage, whereas define means to elaborate something fully.
It's hard to explain without using the word difference, but here's an example: The difference between 5 and 7 is 2. 7 minus 5 = 2
the difference between has and have is that you use has in sentences with : ( she , he and it ) for example : she has a book . but you use have in sentences with : ( I , you , we and they ) for example : you have a book , I have a book .
An example of a derived preposition is "inside," which is derived from the preposition "in" and the noun "side."
It's only called the difference if it is the answer to a subtraction. That is because that is the "difference" between the two numbers. For example: 5 - 2 = 3. 2 is 3 numbers away from 5. It's hard to explain, but hope I helped.
example given......in example
It means to explain the differences between one thing and another thing. For example: Can you differentiate "power" and "force"? Or, can you differentiate "history" and "myth"?
Well, adding x10 is scientific notation. Example:456-4.56x102. this is because there are two numbers before the decimal. another example:14945-1.4945x104. if you do not get it, I'm sorry. This is the best i can explain
