From Columb's Law which describe the electrostatic interaction.
The formula is given and looks as follows
where:
F is force acting between charges,
q1 - charge one given in columbs,
q2 - charge two given in columbs,
r - distance between charge in meters
k - constant
First, we have to convert out formula to get r.
Now we multiplaty by
both sides of equation
Now we devide both sides by F
Next step is take square root
We have all date, we can subsitute it to our formula
Answer:
Materials that can be magnetized, which are also the ones that are strongly attracted to a magnet, are called ferromagnetic (or ferrimagnetic). These include the elements iron, nickel and cobalt and their alloys, some alloys of rare-earth metals, and some naturally occurring minerals such as lodestone.
Hope it helps

Answer:
add a subscript of 4 after the O
Explanation:
The chemical formula of a compound is said to contain the elements in that compound with the respective number of atoms in each element. When writing chemical formula of a compound, the chemical symbols of each comprising element must be known. In this case involving Phosphorus tetraoxide, the symbols of the elements in this compound has been identified as P for Phosphorus and O for oxygen.
After identification of elemental symbols in the compound, Sebastian must now allocate the number of atoms that each element contains. According to the name of the compound, TETRA preceding oxygen means four (4), hence, four will be added as a subscript to O. Hence, at the end, the chemical formula will be PO4.
Please note that, the order of the chemical formula will go as the name implies Phosphorus tetraoxide, so phosphorus symbol (P) comes first, followed by oxygen symbol (O)
<span>1 represents condensation and 2 represents precipitation.
During the condensation, the water that rise through evaporation will be transformed into liquid form.
During the precipitation, this liquid form will fall to the ground because of gravity, and created what we commonly known as the rain</span>
