<u>RESEARCH ON PROXIMA CENTAURI:</u>

  • Robert Innes discovered proxima centauri which is closest to the Sun in 1915 and it is believed to be 4.85 billion years old.
  • Innes used a blink comparator though later he was in competition with another scientist named, Voute who provided theoretical values pertaining to the star more accurately than Innes.
  • The recent findings found a planet which is located close to the Proxima Centauri making it the closest planet to our Solar System.

When wind slows down, it deposits sediment. What feature is created by the deposition of loosely packed, mineral-rich soil?.
sineoko [7]

Answer:  In some parts of the world, windblown dust and silt blanket the land. This layer of fine, mineral-rich material is called loess. Loess is mostly created by wind, but can also be formed by glaciers. When glaciers grind rocks to a fine powder, loess can form.

There are nearly 300 million passenger cars in the U.S. The average gas mileage is 25 MPG (miles per gallon) and each car is dri
Natasha_Volkova [10]

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>
