Gravity is a pair of forces of attraction between every
two objects. Period !
It doesn't matter whether they're moving together, moving apart,
moving gracefully in synchrony, or at rest. The gravitational forces
of attraction between them are always there.
Answer:A loudspeaker produces a musical sound by means of the oscillation of a diaphragm. The loudness of sound produced depends upon Amplitude of vibration.
<u>Explanation:</u>
The loudness of a sound depends upon the amplitude of vibrations. A sound will be louder if the amplitude of vibration is greater but if it is smaller than sound will not be louder.
Now it is the vibration of a sound that determines it's amplitude. Amplitude signifies the maximum distance moved. It means the extent of vibration If is vibrations have more amplitude than sound will be louder but if the amplitude of vibrations is shorter than the sound will be softer.
The SI unit for velocity and speed is meters per second
Answer:
7500 m/s
Explanation:
We can use the equation velocity of a wave equals wavelength times frequency. Therefore, v = wavelength*f = (25 m)(300 Hz) = m/s7,500
