Hi There! :)
An equilibrium constant is not changed by a change in pressurea. True
b. False
False! :P
Heres your great lovley answer that you need
Momentum = mass * velocity
I need parts A and B to explain the intuitions.
Answer:Sound waves are longitudinal waves that is, are transmitted in the same direction of oscillation of the particles in the medium. Electromagnetic waves are transverse ie, the electric and magnetic fields, which are perpendicular to each other, oscillate perpendicularly to the direction of wave propagation.
Explanation:
The formula v=fλ can be used here.
326=2500*λ
Note the 2500 as 2.5kHz is 2.5 thousand Hz.
λ = 326/2500
= 0.1304m = 0.130m
