340 m/s, select those that apply. The music is out of phase with the fireworks and occurs about 3 seconds late. The booms are so loud they occur at the same time as the flash of fireworks explosion. The booms follow the flashes you see by about 3 seconds. The music has the wrong pitch with its frequency changed
Displacement, Velocity and Acceleration
In classical mechanics, kinematics deals with the motion of a particle. It deals only with the position, velocity, acceleration, and displacement of a particle. It has no concern about the source of motion.
Linear Displacement
The term "displacement" refers to when something shifts away from its original "location," and "linear" refers to a straight line. As a result, “Linear Displacement” can be described as the movement of an object in a straight line along a single axis, for example, from side to side or up and down. Non-contact sensors such as LVDTs and other linear location sensors can calculate linear displacement. Non-contact sensors such as LVDTs and other linear location sensors can calculate linear displacement. Linear displacement is usually measured in millimeters or inches and may be positive or negative.
While attending a large fireworks event with music, you decide to stay 1 kilometer away because of the crowds. However you have a good view, and you can still hear the booms, as well as the music. Given a speed of sound on a warm moist summer night of 340 m/s, select those that apply.
