Question:

Why are greenhouse gases so dangerous?

Inactive
Curt Y.

The greenhouse is dangerous because they are one of the main cause of global warming. Typically, the earth reflects the suns dangerous ultraviolet (UV) rays back into outer space. However, greenhouse gases are much more potent in our atmosphere now than ever. These gases trap the UV rays in the atmosphere, which causes the earth to warm. These greenhouse gases are mostly caused by carbon dioxide (C02) and methane (CH4) production.

Question:

How can I simplify..... (x+5)/5 = (x-12)/2

First, take the numbers that are in the denominator by and cross multiply them by the numbers in the numerator. It would then look like this... 2(x+5)=5(x-12) Next, distribute those numbers. 2x+10=5x-60 Then combine the like terms. 70=3x Finally, solve for x 70/3=x x=23.3

Question:

How do equal and opposite forces work?

Inactive
Curt Y.

Equal and opposite forces work in terms of Newton's third law. This meaning for every action there is an equal and opposite reaction. My favorite example is a ball bouncing. When the ball drops gravity pulls it down. Once the ball hits the floor it bounces back up. The action was the ball falling and hitting the floor. The reaction to that was the ball bouncing back up. The bounce is caused by the ball applying the initial force onto the floor and then floor applying that same force back into the ball. This is what is causing it to bounce back up into the air.
