Answer: Longitudinal waves
Explanation: For a sound wave traveling through air, the vibrations of the particles are best described as longitudinal. Longitudinal waves are waves in which the motion of the individual particles of the medium is in a direction that is parallel to the direction of energy transport
A. Reducing the rock's exposure to water
hoped this helped!! :3
Velocity adds direction to speed; it is the rate of travel in a particular direction. To calculate velocity, divide distance traveled by the time it took to travel that distance and add direction. If one's position does not change, velocity is zero.
A would be the correct answer. Its the only one to make sense since you are trying to solve the conflict!
Answer:
sin 40 = n sin 26 snell's law for incoming ray in air
n = sin 40 / sin 26 = 1.47
