Many marine species, including coral, need calcium carbonate to build their protective shells and exoskeletons. Without it, shells grow slowly and become weak. Therefore, ocean acidification impacts Coral reefs with breakable, slow-growing corals erode more quickly than they accrete.
Answer: 355.66 m/s
Explanation:
Since sound is a mechanical wave, its speed varies with the medium and its properties, such as its temperature.
So, if we want to calculate the speed of sound in air at we can use the following equation that relates with the temperature:
(1)
Where:
is the Heat capacity ratio for air
is the Universal Gas constant
is the air temperature in Kelvin
is the air molar mass
(2)
Finally:
This is the speed of sound at 313 K
Answer:
Explanation:
I don't think so. Think about it. To compress the volume by a factor of 2 it takes 956 Joules.
Now you come along and you want to get the pressure for 1/12 of the volume. It's going to take a huge pressure to do that.
I would suggest that you have to use a modified form of the formula.
PV = 956
You need to compress the volume by 1/6
P(V/6) = 956
6 * PV/6 = 6 * 956
PV = 5736 J
Why did I only take 1/6? Because. 956 represents the pressure needed for 1/2 the volume. You need to multiply 1/2 * 1/6 to get 1/12
