Particles vibrate parallel to the direction the sound travels. It's a longitudinal wave.
Because the air in their wings helps them fly
Answer
By F = -kx {-ve just indicating the sign of the force}
=>35 = k x (85-50) x 10^-2
=>k = 100 N/m
Again by F = -kx
The intensity of a sound wave is defined as the amount of energy passing through a unit area of the wave front in unit of time.
