<span>Carbon atom showing 6 protons as electro positive charge in its nuclei should have same no of -ve charged electrons , that is 6 electronns in its radii to make an atom of C as a neutral element , for that each element in its atomic state should have equal no of protons and electrons , the no of neutrons which has no electric charge and almost negligible weight does play significant role except contributes to isotopes of the given atom or an element, so C atom having 6 protons should have 6 electrons</span>
Answer:
10 cm/sec
Explanation:
using formula velocity = frequency * wave length
where: f=1/T
1/1=1
so frequency will be 1HZ ( due to 1 oscillation in 1 sec)
wave length will be 10 cm because while sloshing cup hold (1/2) half full length.
velocity = 1*10 = 10cm/sec.
velocity = 10 cm/sec
