In an ecosystem,disadvantage of using wind as an energy source is that it produces a lot of waste.
What is an ecosystem?Ecosystem is defined as a system which consists of all living organisms and the physical components with which the living beings interact. The abiotic and biotic components are linked to each other through nutrient cycles and flow of energy.
Energy enters the system through the process of photosynthesis .Animals play an important role in transfer of energy as they feed on each other.As a result of this transfer of matter and energy takes place through the system .Living organisms also influence the quantity of biomass present.By decomposition of dead plants and animals by microbes nutrients are released back in to the soil.

in hydraulic pressure the area of the larger piston is half of the smaller piston.if the force of 4000N is applied on the smaller piston.what is the distance covered by the train ?
Answers
Answer:
The distance moved by the train is half the distance moved by the force
Explanation:
Given that the force applied to the smaller piston, F₂ = 4,000 N
The pressure in the area of the larger piston, A₁ = 2 × The pressure in the smaller piston, A₂
∴ A₁ = 2 × A₂
We have;
[tex]\dfrac{A_1}{A_2} = \dfrac{2\cdot A_2 }{A_2} =2 = \dfrac{F_1}{F_2}[/tex]
F₁ = 2·F₂ = 2 × 4,000 N = 8,000 N
F₁·d₁ = F₂·d₂
∴ 8,000 N ×d₁ = 4,000 N × d₂
d₁ = 1/2·d₂
∴ The distance moved by the train is half the distance moved by the force

An echo returned in 3s. What is the distance of the reflecting surface from the source, given that the speed of sound is 342ms^-1
Answers
Answer:
d = 513 m
Explanation:
Given that,
An echo returned in 3s.
We need to find the distance of the reflecting surface from the source, given that the speed of sound is 342 m/s.
The sound will cover 2d distance. The formula for the speed is given by :
v = d/t
So,
[tex]v=\dfrac{2d}{t}\\\\d=\dfrac{vt}{2}\\\\d=\dfrac{342\times 3}{2}\\\\d=513\ m[/tex]
So, the required distance is 513 m.

A construction worker transfers 6000000 J in a n 8 hour day of work. What is their average power output? just need a quick answer with the working, thanks
Answers
Answer:
208.33 W
Explanation:
Using,
P = W/t.......................... Equation 1
P = Average power output, W = total work, t = total time.
From the question,
Given: W = 6000000 J, t = 8 hours = (8×60×60) = 28800 s
Substitute these values into equation 1
P = 6000000/28800
P = 208.33 W.
Hence the average power output is 208.33 W

Answers
Answer:
Finley, Xander and Max
Explanation:
v = Final velocity
t = Time
u = Initial velocity = 0
a = Acceleration
From kinematic equations we get
[tex]v=u+at\\\Rightarrow a=\dfrac{v-u}{t}=\dfrac{v-0}{t}\\\Rightarrow a=\dfrac{v}{t}[/tex]
Xander
v = 4.5 m/s, t = 3.5 s
[tex]a=\dfrac{4.5}{3.5}\\\Rightarrow a=1.29\ \text{m/s}^2[/tex]
Finley
v = 3.6 m/s, t = 4.2 s
[tex]a=\dfrac{3.6}{4.2}\\\Rightarrow a=0.86\ \text{m/s}^2[/tex]

v = 7.3 m/s, t = 1.2 s

The process by which a seed enters a rock fracture and the expanding roots push to widen the fissures is known as mechanical weathering.
What do you mean by mechanical weathering?Machine-induced weathering Mechanical weathering, sometimes referred to as physical weathering and disaggregation, causes rocks to break down. Water, whether liquid or solid, is usually present during mechanical weathering. For instance, liquid water may seep through fractures and fissures in rock.
You may get mechanical weathering from
the reduction in pressure produced on by the removal of subsurface rock.
Water freezes and thaws in the granite's crevices.
Salt crystals are developing inside the rock.

The information is ,
Let's say the weathering looks like A.
Now, plants are to blame since a seed that falls into a fracture in a rock and the seed's expanding roots push and widen the original gap
Weathering from mechanical sources and one mechanical weathering mechanism that fractures rocks is the freezing and spreading of ice in rock cracks.
Moreover, mechanical weathering reduces rocks into microscopic fragments, increasing the surface area of the material as a whole.
Hence, the method is mechanical weathering.

The tuning fork has a frequency of 426.7 is found to cause resonance in a closed column of air measuring 0.186 (the diameter of the tube is 0.015m) find the velocity of the sound produced by the tuning fork.
Answers
Answer:
The velocity of the tuning fork sound is 317.4648 m/s
Explanation:
The given parameters are;
The frequency of the fork, f = 426.7 Hz
The length of the closed air column, L = 0.186 m
The diameter of the tube, d = 0.15 m
At the fundamental frequency in a closed tube, we have;
λ = 4·L
Where;
λ = The wavelength of the wave
L = The length of the tube
From the equation for the velocity of a wave, we have;
v = f·λ
Where;
v = The velocity of the (sound) wave
f = The frequency of the wave = 426.7 Hz
λ = 4·L = 4 × 0.186 m = 0.744 m
∴ v = 426.7 Hz × 0.744 m = 317.4648 m/s
Therefore, the velocity of the sound produced by the tuning fork, v = 317.4648 m/s

You are flying 75.0 mi/hr on a plane heading north with a wind blowing 15.0 mi/hr 46.0° East of North. What is the resultant velocity (your velocity relative to the ground)?
Answers
Answer:
The resultant velocity is 86.1 mi/h.
Explanation:
The law of cosines is given by:
[tex] c^{2} = a^{2} + b^{2} - 2abcos(\theta) [/tex]
Where:
c: is the resultant velocity =?
a: is the velocity of the plane = 75.0 mi/h
b: is the velocity of the wind = 15.0 mi/h
θ: is the angle between "a" and "b"
The angle between "a" and "b" can be found as follows:
[tex] \theta = 180.0 - 46.0 = 134.0 ^{\circ} [/tex]
Now, by using the law of cosines we have:
[tex] c^{2} = (75.0)^{2} + (15.0)^{2} - 2*75.0*15.0*cos(134.0) = 7413.0 [/tex]
[tex] c = 86.1 mi/h [/tex]
Therefore, the resultant velocity is 86.1 mi/h.
The law of sines is:
[tex] \frac{a}{sin(\gamma)} = \frac{b}{sin(\alpha)} = \frac{c}{sin(\theta)} [/tex]
Where:
γ: is the angle between "b" and "c"
α: is the angle between "a" and "c"
So, if we want to find "c" by using the law of sines, we need to know another angle besides θ (γ or α), and the statement does not give us.
