⬇️Here is your answer ⬇️
✨ Frequency determines the pitch of a sound.✨
✨The most common application of chemical effect of electric current is electroplating.
It is a process in which a layer of one metal is coated with another by electrolysis.✨
✨The general range of hearing of human ears is 20 Hz.✨
✨The pressure exerted by air on us is known as atmospheric pressure. It is force per unit area exerted against a surface.✨
✨The frictional force force exerted by fluids is known as drag.✨
⭐Hope it helps you⭐
☺️ Thank you☺️
