Larger tug force = 2*cos20 forward + 2*sin20 to the right (starboard)
<span>Smaller tug force = 1*cos15 forward + 1*sin15 to the left (port) </span>
<span>Resultant force forward = 2*cos20 + 1*cos15 = 2.8453 (4dp) </span>
<span>Resultant force to right = 2*sin20 - 1*sin15 = 0.4252 (4dp) </span>
<span>Angle of resultant force = arctan(0.4252 / 2.8453) = arctan(0.1494) = 8.5 degrees</span>
It can be disproved with <span>one reproducible experiment.</span>

Answer</h2>
The <u>electron affinity in chemical reaction</u> decides the formation of breakdown of substance
<h2>
Explanation</h2>
Within the chemical reactions, different reactants are come together to make the new compound to complete up to the reaction. The reaction is based on the stability of reactants and the electron affinity of these reactants. The oxidation and reduction process within the reaction is also the main reason to combine or break the substance. For example

The hydron has the ability to lose electron and fluorine has the ability to gain an electron. The strong or weak electron affinity of this element makes the new compound HF.
It can also be called the thermal kinetic energy. The internal energy of a system is the total thermal kinetic energy and thermal potential energy of all its atoms and molecules. The Kinetic Theory of Matter is explains the kinetic energy of particles in an object.
