Question

Q1:Define:
a)HERTZ:
b)AMPLITUDE:
c)VOICEBOX:​

Answer 1

Answer:

• cycles per second
• The number of hertz (abbreviated Hz) equals the number of cycles per second. ... The frequency of any phenomenon with regular periodic variations can be expressed in hertz, but the term is used most frequently in connection with alternating electric currents, electromagnetic waves (light, radar, etc.),and sound.

• The amplitude of a periodic variable is a measure of its change in a single period. There are various definitions of amplitude, which are all functions of the magnitude of the differences between the variable's extreme values. In older texts, the phase of a period function is sometimes called the amplitude.

• Listen to pronunciation. (voys …) The area of the throat containing the vocal cords and used for breathing, swallowing, and talking. Also called larynx.

Answer 2

Answer:

a) a unit of frequency equal to one cycle per second —abbreviation Hz. Hertz.

b)The height from the centre line to the peak (or trough) of a periodic function. 

Or we can measure the height from highest to lowest points and divide that by 2.

c)Listen to pronunciation. (voys …) The area of the throat containing the vocal cords and used for breathing, swallowing, and talking. Also called larynx.

Hope it is help full.
