<em>remember that
<u>loudness is directly proportional to the square of amplitude...
</u>so when amplitude is doubled ,,loudness increases four times..
when it is halved ,,,loudness is halved,,,</em>
Answer:
hi how are u fine thanks you
The instantaneous velocity is at a given instant in time while the average is calculated over the time interval of the entire journey. The instantaneous velocity can be determined by finding the gradient of the displacement/time graph while average velocity is given by total distance covered divided by total time taken.
<span>One of the methods that best
describe the reduction of energy is energy conservation. It is the usage of
less energy service that it usually utilizes. An example is using bike for
transportation instead of a car to save fuel. The answer is letter B. It is not
energy efficiency because it represents how efficient a substance can convert work
at 100%. It is not reservation because there is no term for it. It is not
energy holding because it defines the how much energy the body can hold.</span>
