A region within a magnetic material in which magnetization is in a uniform direction this means the individual magnetic moments of the atoms are aligned with one another and they point the same direction. when cooled bwlow a temperature called the curie temperature the magnetization of a piece of ferromagnetic material.<span />
If the element's atomic mass is accurate enough you should be able to tell from that , however if it isn't you would most likely want the number of neutrons or electrons contained by the atom.
The average density of the material from which the coin is made is 9.67 g/cm³.
<h3>Volume of the coin</h3>
The volume of the coin at the given diameter is calculated as follows;
V = Ah
where;
- A is area of the coin
- h is the thickness of the coin
V = πd²/4 x h
V = π(2.8)²/4 x (0.21 cm)
V = 1.293 cm³
<h3>average density of the coin</h3>
The average density of the material from which the coin is made is calculated as follows;
density = mass/volume
density = 12.5 g / (1.293 cm³)
density = 9.67 g/cm³
Thus, the average density of the material from which the coin is made is 9.67 g/cm³.

Answer:
Explanation:
the speed of the tsunami will be
v = distance / time
v = s/t
v = 2300 / 5.3
v = 434 miles/hour
To convert this to m/s, we should note that, 1 mile = 1609 m, and thus
434 miles/hr = 434 * 1609/3600
434 miles/hr = 194 m/s
The frequency, f is given by the formula
f = velocity * wavelength
f = vλ
f = 194 * 470
f = 91180 Hz = 91 kHz
Period, T = 1/f
Period T = 1.096*10^-5 s or
Period T = 1.096*10^-5 / 60
Period, T = 1.828*10^-7 minute
