In Longitudinal waves, particles of the medium vibrate around their mean positions. Their amplitude of vibration is in the direction of the propagation of the wave. In transverse wave of longitudinal wave, <em>the wavelength is always the distance between two particles which are in the same phase.</em>
If we take pressure waves, (sound waves), we have pressure variations created by sound wave along its path. Pressure is maximum at compression regions and pressure is minimum at rarefaction region. In between the two, pressure of air remains as the pressure when there is no wave.
<em>The wave length is then the distance between two consecutive rarefactions or two consecutive compression regions.</em>
<em>It is also the distance traveled by the wave in one time period.</em> Time period is the time the particles in the medium take to vibrate towards the end, turn back to reach the other end of their oscillation and then reach back their position.
Earth quakes are commonly found along fault lines or tectonic plates.

Answer:
here 20 lb object will hit the ground first
Explanation:
Acceleration of the object while it is dropped in air is given as
so acceleration of the object is independent of the mass of the object
now time to reach the ground is given as
for 20 pound object
for 50 pound object
Answer:
The strength of the magnetic field is 0.0842 mT
Explanation:
Given:
Velocity of rod 
Length of rod 
m
Induced emf across the rod 
V
According to the faraday's law
We have a special case for moving rod in magnetic field.
Induced emf in moving rod is given by,
Where 
strength of magnetic field
T
mT
Therefore, the strength of the magnetic field is 0.0842 mT
Answer:
making sure that you change one factor at a time while keeping all other conditions the same
