Answer:
Its probably D (the sound energy)
Snell's law<span> (also known as </span>Snell<span>–Descartes </span>law<span> and the </span>law<span> of refraction) is a formula used to describe the relationship between the angles of incidence and refraction, when referring to light or other waves passing through a boundary between two different isotropic media, such as water, glass, or air.

Answer:
VR=2
Explanation:
driven=60
driving=30
but VR=driven/driving
VR=60/30
VR=2
hence the velocity ratio VR is 2
Answer:
Less than
Explanation:
Speed of sound increases with density of the medium. Since wood is less dense than water, the speed of sound is lower in wood.
Answer:
Multiply the mass times the speed for both, then compare.I would expect the mass of the oil ship to be more than 10 times the mass of the car, in which case its momentum would be greater.
