Identify how the energy flows up through the ecosystem. Describe how decomposers help to cycle matter in an ecosystem and their

NNADVOKAT [17]

Answer:

Decomposers are organisms that break down dead or decaying organisms, they carry out decomposition, a process possible by only certain kingdoms, such as fungi. Like herbivores and predators, decomposers are heterotrophic, meaning that they use organic substrates to get their energy, carbon and nutrients for growth and development. While the terms decomposer and detritivore are often interchangeably used, detritivores ingest and digest dead matter internally, while decomposers directly absorb nutrients through external chemical and biological processes. Thus, invertebrates such as earthworms, woodlice, and sea cucumbers are technically detritivores, not decomposers, since they must ingest nutrients - they are unable to absorb them externally.

The maximum stress in a section of a circular tube subject to a torque is τmax = 27 MPa . If the inner diameter is Di = 3.75 cm

DIA [1.3K]

Answer:

$T_{max} = 4.735\,kN\cdot m$

Explanation:

The shear stress due to torque can be calculed by using the following model:

$\tau_{max} = \frac{T_{max}\cdot r_{ext}}{J_{tube}}$

The maximum torque on the section is:

$T_{max} = \frac{\tau_{max}\cdot J_{tube}}{r_{ext}}$

The Torsion Constant for the circular tube is:

$J_{tube} = \frac{\pi}{32}\cdot (D_{ext}^{4}-D_{int}^{4})$

$J_{tube} = \frac{\pi}{4}\cdot [(0.053\,m)^{4}-(0.038\,m)^{4}]$

$J_{tube} = 4.560\times 10^{-6}\,m^{4}$

Now, the require output is computed:

$T_{max} = \frac{(27\times 10^{3}\,kPa)\cdot (4.560\times 10^{-6}\,m^{4})}{0.026\,m}$

$T_{max} = 4.735\,kN\cdot m$

A ray of light strikes a mirror with an angle of incident of 48º. Calculate: i) the angle of reflection and ii). the angle of de

Arada [10]

Answer:

I) angle of reflection = 48 degrees

II) angle of deviation = 0

Explanation:

Given that the:

angle of incident = 48º.

According to law of reflection which state that the angle of incident is equal to the angle of reflection.

I.) Therefore,

angle of reflection = 48º.

II.) There can only be deviation if the mirror has a diffused surface. But for a smooth plane mirror, there can never be any deviation.

Therefore ,

The angle of deviation = 0

The missile s engine exerts a 260-kN force F.

alexdok [17]

Answer:

a)F=(208 i+156 j) kN

b)F+W=219 kN

Explanation:

Solution:

To determine the components of F

F=(260 kN).( $\frac{4}{\sqrt{4^{2}+3^{2}}}i+\frac{3}{\sqrt{4^{2}+3^{2}}}j$ )

=(208 i+156 j) kN

F=(208 i+156 j) kN

b)weight W expressed in component and add into the

Force F.

W=-(8800 kg).(9.81 m/s^2)j

F+W=(208 i+[156-86.3]j) kN

F+W= $\sqrt{(208kN)^{2}+(-69.7kN)^{2} }$

=219 kN

F+W=219 kN
