energy source
Explanation:
After wire and filament have been connected, for the conduction of electricity, an energy source is required.
In the energy source, electrical energy is produced.
- The energy source can be a simple electrochemical cell.
- It can be a generator.
- It can also be current from the national grid.
- The energy source produces current which is carried in wire and it powers the filament

The object with dimensions
and with mass 250.6 g will have a density equal to
.
<h3>
<u>Explanation:</u></h3>
<u>Given:</u>
Dimensions of the object =
length = l = 5.54 cm
width = w = 10.6 cm
height = h = 199 cm
Mass of the object = m = 250.6 g
<u>Formula:</u>
The relation between density, mass and volume of any object is given by:

Since volume of an object with length (l), width (w) and height (h) [assuming a rectangular object] can be defined as,




Density of the object is 
Answer: Stock nomenclature of
is ammonium(I) nitrate
Explanation:
Stock nomenclature is used for chemical nomenclature where the oxidation states of some or all of the elements in a compound are indicated by Roman numerals in parentheses.
For example:
which has iron in oxidation state of +2 has stock nomenclature of iron(II) chloride.
which has iron in oxidation state of +3 has stock nomenclature of iron(III) chloride.
Thus the stock nomenclature of
is ammonium(I) nitrate as ammonium has oxidation state of +1.
Answer:
mixture
Explanation:
The properties of the components of substance are different. One component has magnetic properties, another does not. So, we have at least 2 individual substances that were mixed together. So, we have a mixture.
