The answer here is letter C. The optimal solution. The optimal solution is the one that affects how certain things changes with sensitivity analysis. The optimal solution is a feasibility solution where the objective function of it is to reach the minimum and maximum value.
Answer:
E. just before it reaches the ground.
Explanation:
The "kinetic energy" refers to the energy<em> when an object moves or is in motion.</em> When the ball leaves the racket, it is considered to have a great amount of kinetic energy. However, this decreases as the ball reaches its maximum height, but the potential energy is at its highest. Upon falling down, its kinetic energy increases but its potential energy decreases.
<em>Provided that there's no air resistance,</em><em> the speed of falling is even faster for the ball because of gravity and nothing is slowing it down, </em>which means it will have a<u> maximum kinetic energy</u><u> just before it reaches the ground.</u>
Answer:
To calculate the pH of an aqueous solution you need to know the concentration of the hydronium ion in moles per liter (molarity). The pH is then calculated using the expression: pH = - log [H3O+].
Explanation:
Reduction takes place in cathode while oxidation takes place at the anode.
Given that the reaction 3MnO4- +24H + +5Fe→3Mn+2+5Fe+3+12H2O
Now that oxidation is termed as an increase in oxidation number or loss of electrons while reduction is a decrease in oxidation number and gain of electrons,
∴oxidation will be
Fe→Fe +3+3e-
reduction will
MnO4- +8H+ →Mn+2+4H2O
If oxidation takes place at anode then Anode: an oxidation reaction
Fe→Fe+3+3e- . Then the answer is
Fe(s)→Fe+3(aq)+3e-
