Describe the forest ecosystem with examples​
Andreyy89

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! :)

yarga [219]

Answer:

V_2=6.17\ m/s

Q=0.49\ m^3/s

Explanation:

Given that

A_1=0.03m^2

A_2=0.08m^2

We know that from continuity equation

Q=A_1V_1=A_2V_2

So

A_1V_1=A_2V_2

0.3V_1=0.08V_2

V_1=2.66V_2

Now from energy equation

P_1+\dfrac{1}{2}\rho V_1^2=P_2+\dfrac{1}{2}\rho V_2^2

P_2-P_1=\dfrac{1}{2}\rho V_1^2-\dfrac{1}{2}\rho V_2^2

140=\dfrac{1}{2}\times 1.2\times 7.11\times V_2^2-\dfrac{1}{2}\times 1.2\times V_2^2

V_2=6.17\ m/s

Q=A_2V_2

Q=6.17 x 0.08

Q=0.49\ m^3/s

What is one way that continental rifts are similar to mid-ocean ridges and what is one that they are different?
adell [148]

Explanation:

Continental rifts and mid-ocean ridges are both features of a divergent plate margin.

In both cases plates are moving away from one another. Therefore they are creating new land masses.

  • A continental drift like the east African rift valley is where a continent begins to pull apart or diverges.
  • A mid-ocean ridge is divergent margin in the ocean.

They are different in that, continental rift occurs within the continental plate that are on land.

But:

 Mid-ocean ridges are in the oceanic crust in the ocean . They form the largest physiographic structure on the earth surface called the mid-ocean ridge.

An ideal heat engine absorbs heat at 100°C and exhausts heat at 0°C. What is its percent efficiency?
vampirchik [111]

Answer:

26.8 %

Explanation:

TH = 100°C = 100 + 273 = 373 K

Tc = 0°C = 273 K

The efficiency of the heat engine is given by

\eta = 1-\frac{T_{c}}{T_{H}}

\eta = 1-\frac{273}{373}

η = 0.268

η = 26.8 %

Thus, the efficiency of the heat engine is 26.8 %.
