The ear is an organ responsible for hearing and the sense of balance. It contains a number of different components that work together to detect sound and convert it into electrical signals that are sent to the brain. The outer ear, or pinna, collects sound waves and directs them into the ear canal. The ear …
Communication The loss of hearing can cause difficulties in communication in a variety of ways. First, it can be difficult to understand what others are saying due to reduced sound clarity, which can lead to confusion and frustration. It can also be difficult to follow conversations in noisy environments, as well as to participate in …
Sound is a form of energy that is propagated through a medium such as air, water, or solid materials as a wave. It is created by the vibration of an object, which creates a pressure wave that travels through the medium. The speed of sound depends on the medium it is traveling through; for example, …
Pitch The pitch of a sound is a subjective measure of the frequency of the sound and is related to the perceived highness or lowness of the sound. The pitch of a sound is measured in hertz (Hz). Loudness Loudness is a measure of sound intensity, or the volume of a sound. It is measured …

The natural frequency of an object is determined by its mass and stiffness. Heavier objects tend to have lower natural frequencies, because they require more energy to vibrate, while lighter objects tend to have higher natural frequencies, because they require less energy to vibrate. Additionally, stiffer objects tend to have higher natural frequencies, because they …
A simple pendulum is a mass, or bob, suspended from a pivot point, such as a nail or a string, so that it is able to swing freely. When given an initial push, the mass swings back and forth in an arc, repeating the same motion over and over. A simple pendulum is used to …
Natural frequency is the frequency at which an object naturally vibrates when it is disturbed from its equilibrium or rest position. It is an inherent property of the object and is determined by its mass, stiffness, and the medium through which it vibrates. Natural frequencies are also known as resonant frequencies and are used to …
The source of a sound can be any object that is capable of vibrating and producing sound waves. Examples of sound sources include musical instruments, voices, and machines. Man-made sources of sound Musical instruments Voice Household appliances Transportation vehicles Machinery Alarms Speakers Video game consoles Natural sources of sound Wind Thunder Birds Rain Animals Ocean …
Explain what earthing, charging by contact , charging by induction and principles of capacitors are Earthing : Earthing is the process of connecting an electrical system or component to the ground. This helps to protect the system from electrical shocks, short circuits, lightning strikes and other electrical hazards. Charging By Contact : Charging by contact …
