Answer: Examples of nonrenewable resources include crude oil, natural gas, coal, and uranium. These are all resources that are processed into products that can be used commercially. For example, the fossil fuel industry extracts crude oil from the ground and converts it to gasoline.
Answer:
Amplitude is decreased by a factor of if intensity is decreased by a factor of 3.
Explanation:
Intensity of a sound wave is directly proportional to the square of its amplitude.
Therefore, if intensity is and amplitude is , then
, where, is constant of proportionality.
Now, if intensity of sound wave is decreased by a factor of 3. So,
New intensity is,
Plug in for . This gives,
Therefore, amplitude is decreased by a factor of .
This equation will be balanced if the x is a 2 because there are two sodiums on the reactants sides so there must be two sodiums on the products side
Hope this helps
