Answer:
The more energy a sound has the louder we perceive it
Explanation:
To measure volume we use the unit of decibels – abbreviated to dB. The lowest perceivable volume, meaning the quietest sound humans can hear, is 0 decibels. ... Thus, 60 dB are perceived as twice as loud as 50 dB
Answer:
Explanation:
= v/f
^That is the formula we are going to use.
Now, we were given the speed (v), which is 20.
Now we need to find frequency, in order to solve for the wavelength.
Frequency is the amount of waves in a fixed unit of one second, meaning our F value is the value of 5 divided by 4.
5/4 = 1.25
Therefore our F is 1.25
Now lets plug it in
= v/f
= 20/1.25
= 16
Conversion:
= 8
<span>Examples of Newton's 2nd Law If you
use the same force to push a truck and push a car, the car will have
more acceleration than the truck, because the car has less mass. It is
easier to push an empty shopping cart than a full one, because the full
shopping cart has more mass than the empty one.</span>

Answer:
The law of multiple proportions states that when two elements can combine in different ratios to form different compounds, the masses of the element combining with the fixed mass of another element result in whole number ratios. This shows that the law of multiple proportions is followed
