Why do you think there are so many more autotrophs than consumers on Earth?<br> Helppp
goldfiish [28.3K]

There are many Autotrophs than consumers because : Autotrophs are the bases of any food chain/web

<h3>Function of Autotrophs </h3>

Autotrophs capture the energy required for every food chain or web from which sustains other organisms in the food chain form sunlight and chemicals. Also there is always more biomass present in the lower levels of the trophic system as biomass decreases as we move up the food chain.

Since autotrophs are producers, for a healthy food chain there would be more autotrophs than consumers.

Hence we can conclude that There are many Autotrophs than consumers because : Autotrophs are the bases of any food chain/web

A rotating space station is said to create “artificial gravity”—a loosely-defined term used for an acceleration that would be cr
Grace [21]

Answer: 0.313 rad/s

Explanation:

The equation that relates the velocity V and the angular velocity \omega in the uniform circular motion is:

V=\omega.r   (1)

Where r=d/2=100m is the radius of the space station (with a diaeter of 200m) that describes the uniform circular motion.

Isolating \omega from (1):

\omega=\frac{V}{r}  (2)

On the other hand, we are told the “artificial gravity” produced by the cetripetal acceleration a_{c} is 9.8m/s^{2}, and is given by the following equation:

a_{c}=\frac{V^{2}}{r}   (3)

Isolating V:

V=\sqrt{a_{c}.r}   (4)

V=31.3049m/s   (5)

Substitutinng (5) in (2):

\omega=\frac{31.3049m/s}{100m}  (6)

\omega=0.313rad/s This is the angular velocity that would produce an “artificial gravity” of 9 9.8m/s^{2}.

I would appreciate some help.

You oughtta be able to do this one.

The "efficiency" is just the portion of the input work that
comes out in a useful form.

If the efficiency is 70%, that tells you that however much work
you put INto the machine, the machine will do 70% of that much
work for you at the output side.

Put 20,000 J in ... out comes (0.70) x (20,000 J)  =  14,000 J .

What happens to the other 30% of the work you put into it ?
It turns into HEAT.  That's why machines always have to be
cooled somehow while they're running.

Name:
aliya0001 [1]

Answer:

Kinetic energy is 1000 J.

Explanation:

Given:

Mass of the bicycle, m=80\textrm{ kg}

Distance traveled, d=100\textrm{ m}

Time of travel, t=20\textrm{ s}

Unknowns:

Speed of the bicycler, v.

Kinetic energy of the bicycler.

Equation:

Speed of the bicycler is, v=\frac{d}{t}=\frac{100}{20}=5\textrm{ m/s}

Therefore, the kinetic energy of the bicycler is given as,

KE=\frac{1}{2}mv^{2}

Substitute:

Plug in 5 m/s for v and 80 kg for m. Solve for KE.

Solve:

KE=\frac{1}{2}\times 80\times (5)^{2}\\KE=40\times 25=1000\textrm{ J}

Therefore, his kinetic energy is 1000 J.
