We have a wave function: D(y,t) and we want to know some things about it. 1. The direction the wave is travelling is negative y direction or -y. 2. Since sound waves are longitudinal waves, this sound wave is oscillating along the y axis. 3. The wavelength we can get from k=2π/λ, k is the wave number, λ is the wavelength. So λ=2π/k=6.28/8.96=0.7 m. 4. Before i get the wave speed i will calculate the period of oscillation. It can be calculated from: ω=2πf where ω is angular frequency and f is wave frequency. So f=ω/2π=3140/6.28=500 Hz and the period is T=1/f=1/500=0.002 s. 5. Wave speed is v=λ*f= 0.7*500=350 m/s.

I hope it helps! Please mark my answer answer as bräinliest (if my answer is correct). Thank You!
The only item on that list that's a plane is the surface of a flat table. The edge of a desk is a rectangle, square, circle, etc. The intersection of two walls is a part of a straight line. A curve in a road is a part of a circle.
To find the acceleration, we would need to use the equation acceleration= final velocity- initial velocity/elapsed time. Since the final velocity is 35 and the initial velocity is 65, we can subtract 65 from 35 first, which gives us -30. Then if we divide that by the elapsed time, which is 10, we get -3. Your acceleration is -3 meters per second.
Hope this helps! :D
