Be sure to answer all parts. One gallon of gasoline in an automobiles engine produces on average 9.50 kg of carbon dioxide, whic
KIM [24]

Answer:

The answer is below

Explanation:

one gallon of gasoline produces 9.50 kg of carbon.

The total number of cars = 40 million

Distance covered by each car = 7930 miles

Consumption rate of the cars per miles traveled is 23.6 miles per gallon.

Hence the annual gasoline consumption by all the cars in the United States of America = (total number of cars × Distance covered by each car) ÷ Consumption rate of the cars per miles

annual gasoline consumption by all the cars = (40000000 × 7930 miles) ÷ 23.6 miles/gallon = `1.344067797 × 10¹⁰ gallons

1.344067797 × 10¹⁰ gallons = 1.344067797*10^{10}\  gallons *\frac{9.50\ kg}{1\ gallon} =1.276864407*10^{11}\ kg\ of \ carbon\ dioxide

Come up with a definition for density
Fantom [35]

Density measures how tightly packed particles are.

If particles are tightly packed together, they will be more dense.

If they are loosely together, they will be less dense.

However, a common mistake is thinking that if something

is more dense it means that it's heavier.

However, that's not the case.

It has to do with how particles are packed in an object.
