Answer:
D is correct
Explanation:
because
we know that
density of lead is 11.36 g/cm3
and
density of tin is 7.31 g/cm3
so..
density of alloy by mixing 50/50
=(11.36+7.31)/2 g/cm3
=18.67/2 g/cm3
=9.33 g/cm3
They exist in the outer orbitals
The correct option is A.
Climate refers to the long time pattern of weather condition in a particular area. Climate is measured by assessing the patterns of variation in temperature, relative humidity, wind, atmospheric pressure, precipitation and other meteorological variables in a given area over a long period of time.<span />
