The vertical displacement of an ocean wave is described by the function, y = A sin(ωt - kx). k is called the wave number (k = 2π/λ) and has a value of k = 17.5 rad/m. The remaining values are A = 5.5 m and ω = 17.5 rad/s. a) Using y = A sin(B), input an expression for B where the wave would be traveling in the -x-direction. sig. gif?t
b) What is the wave's velocity in m/s?
c) What is the wave's amplitude in m?

the earths atmosphere is made up of nitrogen and oxygen. solids can turn into gasses through a process called sublimation. sublimation is the transition of a substance directly from the solid to the gas phase, without passing through the intermediate liquid phase.

hope this : d

1 the 4 is sig

= initial pressure

= final pressure = 2

= initial volume

= final volume = /4

= initial temperature = 20 c = 20 + 273 = 293 k

= final temperature = ?

using the equation
