D. Focusing
Sound waves reflected in flat surfaces like walls, floors and ceilings results to uneven dispersion of sounds by creating locations with high intensity and another with low intensity. This process is called Focusing and can be undesirable in auditoriums.
Answer:
this one is a hard one ask my freind utterfudolphin
Explanation:
Answer:
Ok what is the question good sir/madam?
Humidity<span> is the amount of </span>water<span> vapor in the air. </span>Humidity<span> varies from place to place and season to season.
</span><span>There are two types of Humidity:
Absolute Humidity and Relative Humidity.
Absolute Humidity is the weight of water vapor in a cubic meter of air. The higher the temperature, the higher the ability of air to hold water. For example, at 20 C, the maximum Absolute Humidity is 17.3 g/m^3. At 50 C, the maximum Absolute Humidity is 83.0 g/m^3. Relative Humidity is the % of water vapor in the air relative to the maximum possible Absolute Humidity.</span><span>
</span><span>When we use the word Humidity in ordinary speech, we're talking about Relative Humidity.
So, if the humidity is 95% or even 100%, that doesn't mean 95% or 100% of the air around us is water vapor; just the amount of water in the air is 95% or 100% of the maximum it can hold.
</span>
Therefore, we wouldn't drown at 95% humidity, we will be uncomfortable due to the heat content of air and water but we are still be able to breathe. I hope this answer helps.
