What makes one sound louder than another?
What makes one sound louder than another? Changing the amplitude of a sound wave changes its loudness or intensity. A string plucked with force has greater amplitude, and greater amplitude makes the sound louder when it reaches your ear. Volume depends on amplitude. Greater amplitude produces louder sounds.

What is the purpose of using positive feedback in amplifier?
What is the purpose of using positive feedback in amplifier? Positive feedback makes the output go more in the direction of the input, it makes small changes of the input into bigger changes. A Schmitt Trigger uses positive feedback uses its gain to make its output snap rapidly in the same direction the input is […]
What factor affects the strength of water current?
What factor affects the strength of water current? Waters density is affected by its temperature and salinity, or saltiness. The colder and saltier the water is, the denser and heavier it is.
