Answer:
Redox reactions
Explanation:
Redox (Reduction-Oxidation) reactions are reactions which involves the transfer of electrons. Here, one specie loses electrons while the other gains the electrons. The loss and gain of electrons makes one atom reduced while the other becomes oxidized. Transfer of electrons from one specie to another would eventually lead to a change in oxidation number of the reactants as they proceed to form products.
In non-redox reactions, there is no loss or gain of electrons and no change in oxidation number. An example is neutralization reaction.
Answer:
<em>If the net force is zero, then the body has an acceleration = 0 m/s²</em>
Explanation:
<em>Force: </em>This is defined as the product of mass of a body and its acceleration. Force is a vector quantity because it can be represented both in magnitude and in direction. The S.I unit of force is<em> Newton (N).</em>
<em>Net Force: </em><em>This is the vector sum of all the the forces acting on a body.</em>
<em>Forces acting in the same direction are added while those acting in opposite directions are subtracted.</em>
<em>Example, if two forces F₁ and F₂ act on a body, in opposite direction, The net force F₃ is express below</em>
<em>F₃ = ma = F₁ - F₂ in the direction of F₁</em>
<em>From the example above, If the net force is zero, then the body has an acceleration = 0 m/s²</em>
Answer:
The number of molecules displaced by a vibration creates the amplitude of a sound. The strength or level of sound pressure. The number of molecules in the sound wave in b is greater than the number in the sound wave in a, therefore the amplitude of the sound wave in b is greater.
