An object must be vibrating in order to produce sound. This vibration creates a disturbance in air particles, which travels in the form of sound waves to our ears, allowing us to hear the sound.
To produce an echo, a sound wave must reflect off a surface and travel back to the listener's ears. This reflection can occur off various surfaces, such as walls, buildings, or mountains, depending on the environment. The time interval between the original sound and its reflection must be at least 0.1 seconds for a distinct echo to be perceived by the listener.
True. In order for sound to be produced, some form of energy must be used to create vibrations in an object, which then propagate through a medium as sound waves.
For an object to make sound, it must vibrate. This vibration creates compression waves in the surrounding medium (such as air), which are perceived by our ears as sound. The frequency of the vibration determines the pitch of the sound produced.
The object must be located beyond the focal point of the mirror for a converging mirror to produce a real image.
An object must be placed beyond the focal point of a concave mirror for it to produce a real image. This real image will be inverted and located on the same side of the mirror as the object.

Because for it to produce its sound, you have to strike it. It also produces sound through the vibration of the metal keys or the instrument as a whole. This is the reason a Glockenspiel can be considered as a Percussion Instrument.

Hi, A loud speaker is essentially just a drum that vibrates at varying frequencies to produce a range of sounds. This is usually done by Magnets (which is why you should NEVER put a speaker next to a TV - the magnets affect the RGB screens) The size of the speaker usually dictates how well it performs at certain tones. General Rule of Thumb is that the bigger the diameter of a speaker, the better it performs with lower range tones, and vice versa. Of course this all goes out the window when it comes to Flat panel speakers - I've no idea how they work.
To be doing work, you must be expending energy or applying effort to achieve a particular task or goal. Work involves the transfer of energy from one object to another, resulting in a change in the state or position of an object.
In order for a force to work on an object, there must be an interaction between the object and another object or system that exerts the force. This interaction requires contact or some form of field that allows the force to be transferred. Additionally, the force must have a direction and magnitude to produce a measurable effect on the object.
An airplane must fly at speeds equal to or greater than the speed of sound, around 768 mph at sea level, to produce a sonic boom. This creates a shockwave caused by the sudden change in air pressure as the aircraft breaks the sound barrier.
