QUESTION -

  In which direction does energy flow in an ecosystem ?


ANSWER -

  The flow of energy in an ecosystem is best described as energy moving in one direction from the sun to the producers then to the consumers. Explanation; Energy flow is the amount of energy that moves through successive trophic levels of a food chain in an ecosystem

1) If a sound with the same amplitude and energy is propagated at a source, predict through which medium the sound will travel t
Lady bird [3.3K]

Answer:

denser media the speed is greater

Explanation:

The speed of sound is given by the relation

  v= \sqrt{\frac{B}{\rho} }

where B is the volume modulus and ρ the density of the medium

When analyzing the previous expression, the amplitude of the sound depends on the energy carried by the wave.

Wave speed, is given by the relationship between two magnitudes, we analyze their values ​​for different media. The volume modulus for gases has values ​​of the order of 10⁵ Pa, for liquids of the order of 10⁹ Pa and for solids of 10¹⁰ to 10¹¹ Pa, while the density has values ​​of the order of 10⁻¹ to 10⁰ kg / m³ for gases for liquids 10³ kg / m³ and for solids of the order of 10³ to 10⁴ kg / m³

 

let's find the order of magnitude of the speed of sound

Gases

     v =√ 10⁵/10⁰ = 300 m / s

liquids

     v =√ 10⁹/10³ = 1000 m / s

solid

     v = √ 10¹¹/ 10⁴ = 3000 m / s

We can see that in denser media the speed is greater

A sprinter starts from rest and accelerates to her maximum speed of 10.5 m/s in a distance of 11.0 m. (a) What was her accelerat
Anvisha [2.4K]

Answer:

a)a=5.01m/s^2

b)t=11.26s

Explanation:

A body that moves with constant acceleration means that it moves in "a uniformly accelerated movement", which means that if the velocity is plotted with respect to time we will find a line and its slope will be the value of the acceleration, it determines how much it changes the speed with respect to time.

When performing a mathematical demonstration, it is found that the equations that define this movement are as follows.

Vf=Vo+a.t  (1)

{Vf^{2}-Vo^2}/{2.a} =X(2)

X=Xo+ VoT+0.5at^{2}    (3)

X=(Vf+Vo)T/2 (4)

Where

Vf = final speed

Vo = Initial speed

T = time

A = acceleration

X = displacement

In conclusion to solve any problem related to a body that moves with constant acceleration we use the 3 above equations and use algebra to solve

to solve the question a, we can use the ecuation number 2

Vo=0

Vf=10.5 m/s

x=11m

{Vf^{2}-Vo^2}/{2.a} =X

{Vf^{2}-Vo^2}/{2.x} =a

{10.5^{2}-0^2}/{2x11} =a

a=5.01m/s^2

to find the time we can use the ecuation number 1

Vf=Vo+a.t

t=(Vf-Vo)/a

t=(10.5-0)/5.01=2.09s

part b

in this case  the spees is constant, so the movement is defined by the following ecuation

X=VT

t=x/v

t=96.3/10.5=9.17s

to find the total time we sum the times when the speed is constant and when the acceleration is constan

t=9.17+2.09

t=11.26s
