Answer : The magnetic moment of a single nickel atom is 
Explanation :
Formula used :

where,
= saturation magnetization = 
N = Avogadro's number = 
V = volume of nickel atom
= magnetic moment
First we have to calculate the volume of nickel atom.




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



Therefore, the magnetic moment of a single nickel atom is 
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.
Answer:
The alphabet comprises 21 consonants and 5 vowels
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.
