Answer:
Wave A= 20m
Wave B= 30m
Explanation:
The amplitude of a wave is the maximum displacement (or height) from its equillibrum position.
The equilibrium position is at 0 meters for both waves.
Thus, amplitude of wave A= 20m
Amplitude of wave B= 30m
Answer : The value of for the reaction is -1131.4 kJ
Explanation :
According to Hess’s law of constant heat summation, the heat absorbed or evolved in a given chemical equation is the same whether the process occurs in one step or several steps.
The given main reaction is,
The intermediate balanced chemical reaction will be,
(1)
(2)
(3)
Now we will reverse the reaction 1, multiply the reaction 2 by 2, reverse and half the reaction 3 and then adding all the equations, we get :
(1)
(2)
(3)
The expression for will be,
Therefore, the value of for the reaction is -1131.4 kJ
