Airplane cabins are pressurized so passengers can breathe comfortably at altitudes of up to 9,200 meters (30,000 feet).The air pressure inside the cabin at this altitude, however, is still lower than the atmospheric pressure at sea level. A passenger opens a resealable bag of raisins before the plane takes off from approximately sea level. He reseals the bag and leaves some air surrounding the raisins. What will the bag most likely look like when the plane is at its highest altitude?

the answer is definitely c.

the product of the pressure and volume is also constant

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

you did not give any options thus this is the best answer i can give to you with this little information you have given

> they are both natural and not man made

> they can be tracked and predicted by the right tools
