At 20 degrees celsius, the density of air is 1.20 g/l. nitrogen's density is 1.17 g/l. oxygen's density is 1.33 g/l. will balloons filled with oxygen rise or sink in the air? will balloons filled with nitrogen rise or sink in the air? why? (3 points)

Answer : When the balloons filled with oxygen then the balloons will sink.

When the balloons filled with nitrogen then the balloons will float.

Explanation :

As we given that:

The density of air = 1.20 g/L

The density of nitrogen = 1.17 g/L

The density of oxygen = 1.33 g/L

Here, substance is nitrogen and oxygen and medium is air.

As per question we conclude that,

The density of substance (oxygen) is greater than the density of medium (air). That means, when the balloons filled with oxygen then the balloons will sink.

The density of substance (nitrogen) is less than the density of medium (air). That means, when the balloons filled with nitrogen then the balloons will float.

Hence, the correct option is, It would float.

wanahton purified a portion of water with 900 grams of contaminants. each hour, a third of the contaminants was filtered out.

let g(n) be the amount of contaminants (in grams) that remained by the beginning of the nth hour. g is a sequence, what kind of sequence is it, arithmetic or geometric? then, write an explicit formula for the sequence, g(n)=
