Answer:

the rocket average speed is 12 kilometers per second

Explanation:

Given that

The distance is 1140 km

And, the time is 95 seconds

We need to determine the average speed in kilometers per second (km/s)

So as we know that

Speed = distance ÷ time

= 1,140 km ÷ 95 seconds

= 12 kilometers per second

hence, the rocket average speed is 12 kilometers per second

Which of these protects the Earth from harmful radiation when found in the stratosphere, but is a pollutant at lower altitudes?
storchak [24]

The correct answer is - ozone.

The ozone is essentially three molecules of oxygen, or O³. This gas is crucial for the life on the Earth because it is the one that manages to filter out big portion of the UV radiation from the Sun which is extremely harmful if its too strong, as it will contribute to the dying out of pretty much every living organism.

While the ozone layer in the stratosphere is very useful, the ozone in the lower parts of the troposphere is actually considered as pollutant. The reason why it is considered as pollutant is because it is very harmful if inhaled, and it also heavily damages the plants.
