How does examining past data help prepare people for feature weather hazards?

It lets people prepare for future weather hazards:

- If, in certain months and on certain dates, the past data shows that there's a history of rain or heat stroke on those days, people can prepare in the future for those events.

- They can also expect wind speeds, temperatures and stuff like that!

where's the diagram?

the density of gold = 19.3 g/cm3

the relation between density and mass and volume is

density = mass / volume

given :

mass of gold = 13 g

density = 13g / volume = 19.3

volume = 13 /19.3 = 0.67 cm^3

thus volume of gold nugget = 0.67 cm^3
