Answer:
No, they are not. The concept of human races appears to be solidly grounded in present-day biology and our evolutionary history. But if you asked that conference of geneticists to give you a genetic definition of race, they wouldn’t be able to do it. Human races are not natural genetic groups; they are socially constructed categories. Genes certainly reflect geography, but unlike geography, human genetic differences don't fall along obvious natural boundaries that might define races.
 
        
             
        
        
        
D= m/v
solve this formula to find v 
by solving we get,
v = m/D
v = 13/19.3
v = 0.67 cm^3

A new moon occurs once every lunar month, and a lunar month lasts 29.5 earth days. Therefore, the new moon may occur either 29 days after this one, on the 30th of October, or it may occur 30 days after this one, on the 31st of October, since there can not be 0.5 days in a month.
