g Indium has two naturally occurring isotopes: 113In with an atomic weight of 112.904 amu, and 115In with an atomic weight of 11

aleksandrvk [35]

Answer:

Fraction-of-occurrences of 115In isotope $= 0.957$

Explanation:

As we know weight of 113 In isotope is equal to the sum of product of fraction-of-occurrences of two constituents isotopes and their atomic weight

$^{115}In_w = f_{113}*A_{113} + f_{115}*A_{115}$ ------(1)

As we know sum of fraction-of-occurrences of two constituents isotopes is equal to one.

$f_{113} + f_{115} = 1\\f_{113} = 1- f_{115}$ ---------(2)

Substituting the given values in equation 1, we get

$^{115}In_w = f_{113}*A_{113} + f_{115}*A_{115}\\114.818 = (1 - f_{115}) * 112.904 + f_{115} * 114.904\\f_{115} = 0.957$

Substituting this value in equation 2 we get -

$f_{113} = 1- f_{115}\\f_{113} = 1- 0.957 \\f_{113} = 0.043$

What purpose does a fish ladder serve?

Whitepunk [10]

Answer: Option A

Explanation :

A fish ladder is also known as fish steps, fish pass or fishway.

It is built around waterfalls, dams and locks.

The purpose of building a fish ladder is to facilitate the natural migration of diadromous fishes.

A fish ladder helps the fish to pass through the barriers by leaping up or swimming through the low steps of the ladder and reach into the water on the other side.

Since, without the fish ladder the barriers will not allow the migration of fishes, it is essential to be built around the dams, waterfalls and locks.
