Awave travels 12 m east in 3.0 s. what is the velocity of the wave?

Answer:  + 4 m/s

Working Out:

V = Δ x  ÷  Δ t ;where V =  velocity, Δ x = displacement, Δ t = change in time

V = Δ x  ÷  Δ t

V = (12 m east) ÷ 3.0 s

V = 4 m/s to the east  OR V = + 4 m/s

∴ The velocity of the wave is + 4 m/s

consider the reaction below.

 no rx

at 500 k, the reaction is at equilibrium with the following concentrations.

[pci5]= 0.0095 m

[pci3] = 0.020

[ci2] = 0.020 m
