Answer:
1.0236 billion metric tons
Explanation:
Given Parameters
Number of cars = 300000000
Average gas mileage per car = 25 MPG
Average distance covered by a car in one year = 10000 miles
CO2 Emission = 8.53 kg/gallon
Derivations from the given parameters,
If the average gas mileage per car is 25 MPG, then the volume of fuel consumed by a car in a year is:
<em>10000 miles ÷ 25 MPG = 400 gallons
</em>
The CO2 emission for one car in a year is:
<em>400 gallons × 8.53 kg/gallon = 3412 kg or 3.412 metric tons (note: 1000 kg = 1 metric ton)
</em>
The CO2 emission for 300000000 cars in year is:
<em>3.412 metric tons × 300000000 = 1023600000 kg = 1.0236 billion metric tons
</em>

Answer:</h2>
<u>c. Solstice</u> describes days when sun's rays directly hit Tropic of Cancer and Tropic of Capricorn.
<h2>
Explanation:</h2>
The solstices occur due to the declination of the Earth's orbital movement around the sun. During this declination, the axial tilt is 23.5°. Furthermore, solstice's occurrence is during time the sun's direction is overhead the moon.
In Northern hemisphere, the declination is towards Tropic of Cancer with the axial tilt of 23.5°N. It occurs on June 20 & 22 while in the south the normal period of occurrence is between December 20 and December 23. In the south, the solar declination hits Tropic of Capricorn at 23.5°S.
