Klio2033 [76]

Answer:

Autotrophs

Explanation:

When you go down a food chain continuing to ask "what does it eat?" the last living thing that you will land upon is an autotroph.

Autotrophs are the primary producers as they (photoautotrophs) use the energy either from the sun to prepare  there food by the process of photosynthesis or, more rarely, obtain chemical energy through oxidation (chemoautotrophs) to make organic substances from inorganic ones.

Autotrophs get consumed by the primary consumers in the food chain.

Because of the curvature of the earth, the maximum distance D that you can see from the top of a tall building of height h is es
mojhsa [17]

Answer:

 D = 9.9 10⁶ mi

Explanation:

In the exercise they give the expression for maximum viewing distance

       D = 2 r h + h²

Ask for this distance for a height of 1100 feet

Let's calculate

        D = 2 3960 1100 + 1100²

        D = 8.712 10⁶ + 1.21 10⁶

        D = 9.92 10⁶ mi

         D = 9.9 10⁶ mi

Zero field spot for opposite unequal charges
xz_007 [3.2K]

Answer:

The zero field location has to be on the line running between the two point charges because that's the only place where the field vectors could point in exactly opposite directions. It can't be between the two opposite charges because there the field vectors from both charges point toward the negative charge.

The ground state energy of an electron in a one-dimensional trap with zero potential energy in the interior and infinite potenti
ElenaW [278]

Answer:

0.5 eV

Explanation:

E_1 = Initial potential energy = 2\ eV

E_2 = Final potential energy

L_1 = Initial width

L_2 = Final width = 2L_1

Energy of an electron in a one-dimensional trap is given by

E=\dfrac{n^2h^2}{8mL^2}

From the equation we get

E\propto \dfrac{1}{L^2}

So,

\dfrac{E_1}{E_2}=\dfrac{L_2^2}{L_1^2}\\\Rightarrow E_2=\dfrac{E_1L_1^2}{L_2^2}\\\Rightarrow E_2=\dfrac{2L_1^2}{4L_1^2}\\\Rightarrow E_2=0.5\ eV

The ground state energy will be 0.5 eV
