A forest ecosystem describes the community of plants, animals, microbes and all other organisms in interaction with the chemical and physical features of their environment: Specifically, a terrestrial environment dominated by trees growing in a closed canopy — a forest, in other words.
Hope this helps you buddy! :)
Answer:
Explanation:
Frequency is mathematically defined as the quotient of speed divided by wavelength.
where
v-is the speed of light
-w is wavelength.
Given the speed of the wave as 
and the wavelength 
, we substitute these values in the Frequency function to solve for frequency:
Hence, the wave's frequency is 
Arteries push blood to the rest of the body after leaving the heart.
The balance of oxygen and carbondioxide is maintained in the atmosphere by the oxygen released by plants during photosynthesis and carbondioxide released by human,animals etc. The balance of oxygen and carbondioxide is made due to respreration and photosinthesis.
Answer:
1 hour
Explanation:
Since the definition of velocity is 
, we can calculate the position at time t of an object moving at speed v with 
.
The position of the first ferry is 
The position of the second ferry is 
We want to know when they will be 6 miles apart. This means, if we call that distance d, that we want to know when the difference between their positions will be d, or 
(we know that at the beginning the position of the ferry 1 is of higher value than that of ferry 2 since it left before).
We use our previous formulas then:
Since we want the time, we do:
And substitute our values:
