C and Si both have same lattice structure; having 4 bonding electrons in each. However C is insulator where as Si is intrinsic semiconductor. This is because In case of C the valence band is not completely filled at absolute zero temperature. In case of C the conduction band is partly filled even at absolute zero temperature. The four bonding electrons in the case of C lie in the second orbit whereas in the case of Si they lie in the third. The four bonding electrons in the case of C lie in the third orbit whereas for Si they lie in the fourth orbit.

Step-by-Step Verified Solution
According to the question,
Damping force, F _ v
_ F = kv
where k is constant of proportionality.
_ k = F v = N m s _ 1 = k g m s _ 2 m s _ 1 = k g s _ 1
