What is the frequency of a sound wave traveling at 335 m/s with a wavelength of .55 m?

Determine the change in width a, height b, thickness t when a plate is subjected to the uniform distributed load and is made of material having modulus of elasticity e=230 gpa and poisson's ratio ν=1/3. given : a=400 mm and b= 300 mm also the uniformly distributed load in downward y direction of plate is 2 mn/m and in the positive x direction is 3 mn/m and t=20 mm

The air that we breath is made mostly of which gaseous molecule

The force needed to overcome static friction is usually less than that needed to overcome kinetic friction.true or false?
