A converging lens made from a transparent plastic bottle filled with water is used to enable Pak Dollah read the newspaper.
<h3>What is long-sightedness?</h3>
Long-sightedness is an eye effect in which objects are not able to focus on the retina but behind the retina, therefore, near objects are not clearly seen except they are placed far away.
To correct long-sightedness, a suitable converging lens is used to bring the image to focus on the retina.
To construct a converging lens for Pak Dollah, the transparent plastic bottle is filled with water to serve as a converging lens and Pal Dollah will read through it.
Therefore, a converging lens made from a transparent plastic bottle filled with water is used to enable Pak Dollah read the newspaper.

1.025 moles of NaCl are present in a solution with a molarity of 8.20M and 125 mL of solution. Details about molarity can be found below.
<h3>How to calculate molarity?</h3>
The number of moles of a solution can be calculated by multiplying the molarity of the solution by its volume. That is;
no of moles = molarity × volume
According to this question, a solution has a molarity of 8.20M and volume of 125 mL of solution.
no of moles = 8.20 × 0.125
no of moles = 1.025moles
Therefore, 1.025 moles of NaCl are present in a solution with a molarity of 8.20M and 125 mL of solution.

Answer: -
A. An uncontrolled nuclear chain reaction is most likely to multiply exponentially.
Explanation: -
An nuclear chain reaction produces neutrons. These neutrons then can start new nuclear fissions. In a controlled nuclear fission, the number of neutrons allowed to start new fission is controlled.
In an uncontrolled reaction, the neutrons start fission very fast. These also start new nuclear fission, releasing more neutrons.
Thus. An uncontrolled nuclear chain reaction is most likely to multiply exponentially.
