Answer:
Option (C)
Explanation:
CO₂ is one of the main green house gases on earth. A small increase in its concentration can lead to significant changes on earth. When the incoming solar radiations are incident on the earth's surface, some of the energy is absorbed by the atmosphere and the earth's surface. And some of the energy from the land surface after absorption is released into the atmosphere in the form of infrared radiations. The escaping of these radiations from earth is directly dependent on the concentration of CO₂. An increase in the amount of CO₂ will not allow these IR radiations to be removed, and this will result in the global rising of the temperature, leading to catastrophic changes.
Thus, the correct answer is option (C).
Extreme natural hazards and population growth
The more northern the more colder the more towards the middle of the earth you are the warmer it is. Either it's ice or water.
Answer:
Full question is attached.
Tommy's reasoning is wrong because the hypotenuse is not 5 feet.
A skateboard ramp resembles a right angles triangle so its sides resemble that of a right angled triangle.
The height of 3 feet would be the height of the triangle.
The length of 5 feet would be the length of the triangle.
The piece of plywood that would cover the top of the frame would be the hypotenuse.
In using the Pythagoras rule, the c is the hypotenuse but Tommy made the mistake of assuming that the hypotenuse was b which is where the error came from.
Instead of solving for b, they should have been solving for c which is the hypotenuse.
a² + b² = c²
3² + 5² = c²
9 + 25 = c²
c² = 34
c = √34
c = 5.83 feet
They should use a plywood of 5.83 feet not 4 feet.
