24 kg create initially at rest on the horizontal for choir is 75 Newton horizontal force to set it in motion when’s the crazies emotion a horizontal force of 53 N keeps the crate moving with a constant velocity find the coefficients of kinetic friction between the crate and the floor

Gotta have a picture ^^

Dshould be the right answer i think

Sounds propagates through some kind of medium. usually it's air, but it goes just as well through solid objects like walls, windows etc. a soundwave will compress the (air)molecules in front of it, and if this increased density wave hits your ears, you register it as sound. solid objects like walls are a lot denser than air, this means that they will damp a wave, but also carry it easier.
