Answer:
The sea affects the climate of a place. Coastal areas are cooler and wetter than inland areas. ... In the summer, temperatures can be very hot and dry as moisture from the sea evaporates before it reaches the centre of the land mass
1. A <em>population density</em>
2. B <em>underpopulation</em>
3. A <em>overpopulation</em>
Answer:
107.3g
Explanation:Density = Mass/Volume
There are two methods either by taking the above formula and inserting the values or by using Mass = Denstiy*Volume
Here I have showed you both the ways:
1st
As Desnity is 21.46g/cm^3
Volume = 5cm^3
Let m be mass
21.46g/cm^3=m/5cm^3
Cross multiplication takes place here
21.46*5=m
107.3 =m
Therefore, mass of platinum = 107.3g
2nd
Mass = Denstiy*Volume
Density = 21.46g/cm^3
Volume = 5cm^3
m=21.46g/cm^3* 5g/cm^3
m= 107.3g
