The outer rigid layer of the earth is divided into a couple of dozen “plates” that move around across earths surface relative to each other.
The answer is; pressure
The sound is a longitudinal wave meaning the particles vibrate parallel to the direction of the wave. Sound waves, therefore, produce compression (akin to the crest in a transverse wave) and rarefaction regions (akin to a trough in a transverse wave) as its energy is propagated in the medium.
Current.A moving charge is an object that changes position to one particular obsever.
Answer:
75 m
Explanation:
The horizontal motion of the projectile is a uniform motion with constant speed, since there are no forces acting along the horizontal direction (if we neglect air resistance), so the horizontal acceleration is zero.
The horizontal component of the velocity of the projectile is
![v_x = 15 m/s](https://tex.z-dn.net/?f=v_x%20%3D%2015%20m%2Fs)
and it is constant during the motion;
the total time of flight is
t = 5 s
Therefore, we can apply the formula of the uniform motion to find the horizontal displacement of the projectile:
![d= v_x t =(15 m/s)(5 s)=75 m](https://tex.z-dn.net/?f=d%3D%20v_x%20t%20%3D%2815%20m%2Fs%29%285%20s%29%3D75%20m)
