Velocity, wavelength, and frequency.
Wave velocity (v) is how fast a wave propagates in a given medium. Its unit is meter per second. Check the speed calculator for more information about speed and velocity.
Wavelength (λ) is the distance over which the shape of a wave repeats. It depends on the medium in which a wave travels. It is measured in meters.
Frequency (f) of a wave refers to how many times (per a given time duration) the particles of a medium vibrate when the wave passes through it. The unit of frequency is Hertz or 1/second.
Answer:
The one with the less mass
Explanation:
C.) Pedestrians yielding to cross traffic.
Answer:
you want to know newtons first law here.
Explanation:
An object that is at rest stays at rest or stays in motion.
According to Boyle’s law, For a fixed amount of an ideal gas kept at a fixed temperature, P (pressure) and V (volume) are inversely proportional.
Therefore,
Given 
, 
and 
.
Thus,
