In the first law, an object will not change its motion unless a force acts on it. In the second law, the force on an object is equal to its mass times its acceleration. In the third law, when two objects interact, they apply forces to each other of equal magnitude and opposite direction.
Explanation:
The kinetic energy of translation
m= mass v= linear velocity
The kinetic energy of rotation
I= MOI of the thin walled sphere =kmR^2
where ω= v/R= angular velocity
Then
=1/k
solid sphere: k=0.4; E1/E2 =1/0.4 = 2.5;
hollow sphere: k=2/3; E1/E2 = 1.5
Explanation: Si4H10+O2>SiO2+H2O
2Si4H10 + 13O2 = 8SiO2 + 10H2O
It is

Answer:
Diamagnetism in atom occurs whenever two electrons in an orbital paired equalises with a total spin of 0.
Paramagnetism in atom occurs whenever at least one orbital of an atom has a net spin of electron. That is a paramagnetic electron is just an unpaired electron in the atom.
Here is a twist even if an atom have ten diamagnetic electrons, the presence of at least one paramagnetic electron, makes it to be considered as a paramagnetic atom.
Simply put paramagnetic elements are one that have unpaired electrons, whereas diamagnetic elements do have paired electron.
The atomic orbital and radius increases by gaining electron linearly so even electron numbered atoms are diamagnetic while the odd electron numbered atoms are paramagnetic.
Running through the first 18 elements one can observe that there is an alternative odd number of electrons and an even number proofing that that half of the first 18 elements shows paramagnetism and diamagnetism respectively.
