Answer:
a)
b)
c)
Explanation:
Given that
Length =L
Mass = m
Force on elemental part
dF= dm ω² r
dm = m/L dr
dF= ω² r m/L dr
By integrating from r to L
Velocity V
The answer is that "elements are a single atom and compounds are a mixture of two elements or more." Elements are atoms that have protons, neutrons, and electrons. Compounds are mixtures with two or more elements.
Hope this helps.
