A scuba diver dives to a depth of 1.25 m below the surface of the sea. The sea water has a density of 1025 kg/m. What pressure does the water exert on the diver?​

Then the answer would be d then

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.
