The answer is;
first blank-
A
Second blank-
B
Activation energy raised the potential energy of reactants to begin a chemical reaction. This requires an initial input of energy into the reaction before the reaction can then proceed spontaneously. That delta G of the activation energy is usually positive. This activation energy destabilized the stable bonds of the reactants so they can form new bonds. This results to a transition state that is a high-energy state.
Answer
given,
wavelength = λ = 18.7 cm
= 0.187 m
amplitude , A = 2.34 cm
v = 0.38 m/s
A) angular frequency = ?
angular frequency ,
ω = 2π f
ω = 2π x 2.03
ω = 12.75 rad/s
B) the wave number ,
C)
as the wave is propagating in -x direction, the sign is positive between x and t
y ( x ,t) = A sin(k x - ω t)
y ( x ,t) = 2.34 x sin(33.59 x - 12.75 t)
