When the ball hits the bat , it will take about a million times longer to hear the crack of the bat than to see it.
What you see is almost instantaneous.
There will be a delay until you hear the sound.
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
The second one is more concentrated as they both times with the same thing but the second one (1.5) is bigger
Answer: Option (D) is the correct answer.
Explanation:
A polymer is a large molecule which contains repeating units.
A polymer forms long chain of atoms which are not necessarily arranged in a ring structure. There are not only double bonds between all the carbon atoms, as there can be single bonds or triple bonds between the atoms of a polymer.
A polymer does not contain many different type of molecules as there are many repeating units and not many molecules in a polymer.
A polymer is made of large molecules with repeating units.
Thus, we can conclude that option (D) is the correct answer.
