Answer:

A.Because Earth's atmosphere causes most objects to burn up before they reach the  surface.

Explanation:

The Earth's surface is rarely impacted by large objects that enters because the atmosphere causes most of the objects to burn up before they reach the surface.

There are different layers of the earth atmosphere which carries various amount of energy and energetic particles.

  • When a massive and a high solar object or dust or rocks are directed towards the earth, they are either deflected or burnt upon their passage through the atmosphere.
  • These energetic particles have ionizing properties and causes the solar particles to burn up.
  • This way the earth's surface is shielded from any impact of any sort.

olasank [31]
The reaction equation is:
<span>2CuO(s) + C(s) </span>→ <span>2Cu(s) + CO</span>₂<span>(g)

First, we determine the number of grams present in one ton of copper oxide. This is:
1 ton = 9.09 x 10</span>⁵ g

We convert this into moles by dividing by the molecular mass of copper oxide, which is:
9.09 x 10⁵ / 79.5 = 11,434 moles

Each mole of carbon reduces two moles of copper oxide, so the moles of carbon required are:
11,434 / 2 = 5,717 moles of Carbon required

The mass of carbon is then:
5,717 x 12 = 68,604 grams

The mass of coke is:
68,604 / 0.95 = 72,214 g

The mass of coke required is 7.22 x 10⁴ grams

ziro4ka [17]

<u>Given:</u>

Initial velocity (v1) = 0 m/s

Final velocity (v2) = 30 m/s

Acceleration (a) = 6.1 m/s2

<u>To determine:</u>

The time (t) taken to reach the final speed

<u>Explanation:</u>

Use the relation:

Acceleration (a) = [final velocity(v2) - initial velocity (v1)]/time (t)

t = (v2-v1)/a = 30-0/6.1 = 4.92 s

Ans: Time taken is around 4.9 s
