Suppose that the saturation magnetization Mmax of the ferromagnetic metal nickel is 4.41 × 105 A/m. Calculate the magnetic momen
Lady bird [3.3K]

Answer : The magnetic moment of a single nickel atom is 4.82\times 10^{-24}Am^2

Explanation :

Formula used :

M_{max}=(\frac{N}{V})\times \mu

where,

M_{max} = saturation magnetization = 4.41\times 10^5A/m

N = Avogadro's number = 6.022\times 10^{23}atoms/mol

V = volume of nickel atom

\mu = magnetic moment

First we have to calculate the volume of nickel atom.

Density=\frac{Mass}{Volume}

8.90g/cm^3=\frac{58.71g/mol}{Volume}

Volume=\frac{58.71g}{8.90g/cm^3}

Volume=6.59cm^3=6.59\times (100)^3m^3

Now we have to calculate the magnetic moment of a single nickel atom.

M_{max}=(\frac{N}{V})\times \mu

4.41\times 10^5=(\frac{(6.022\times 10^{23})}{6.59})\times (100^3)\times \mu

\mu=4.82\times 10^{-24}Am^2

Therefore, the magnetic moment of a single nickel atom is 4.82\times 10^{-24}Am^2

What type of tide would this arrangement of earth-moon-sun create?*
Advocard [28]

Answer:

neap tide

Explanation:

There are two different types of tides, which are the spring tide and the neap tide.

Neap tides are weak tides which occur when the gravitational forces of the sun and the moon are at right angles to each other with respect to the earth. Since the sun and moon are at right angles, it causes a difference between the low and high tide.

The spring tide are strong tides which occur when the moon, sun and earth are in straight line. The spring tide occur during full moon and new moon.

This graduated cylinder has numbers representing milliliters. A student says that the volume of the liquid inside is 21.8 millil
GaryK [48]

Explanation:

The answer for this question depends on the type of meniscus in the cylinder. If it is an upright meniscus like in water, the reading should be taken at the bottom of the meniscus. However if it is an inverted meniscus like in mercury, the reading should be taken at the top of the meniscus.
