TaigaIn a loudspeaker, electrical energy from an amplifier is converted into mechanical energy that vibrates a diaphragm to produce sound waves. The changing electrical signal produces a magnetic field that interacts with a permanent magnet, causing the diaphragm to move and create sound.

Identify to changes of state that require energy to be used and two changes of state that require the release of energy?
Changes of state that require energy: melting (solid to liquid) and vaporization (liquid to gas). Changes of state that release energy: freezing (liquid to solid) and condensation (gas to liquid).
What changes electric energy into kinetic energy?
Electric energy can be converted into kinetic energy through an electric motor. The electric motor uses the magnetic field generated by electric currents to produce rotational motion, which in turn creates kinetic energy in machinery or devices. This process is commonly used in various applications, such as electric vehicles and industrial machinery.
Microphone has been used in interview . which energy takes place in the microphone?
The microphone converts sound energy (acoustic energy) into electrical energy. This electrical signal can then be amplified and transmitted to a recording device or speaker.
What energy changes in washing machine?
The main energy changes in a washing machine are electrical energy being converted into mechanical energy to drive the motor that rotates the drum and agitator, and thermal energy being used to heat water for washing. Additionally, there is energy used for controlling the electronic components and displaying information on the control panel.
Potential energy can be used to do work?
Yes, potential energy is the stored energy an object has due to its position or state. When the object moves or changes its position, this stored energy can be converted into kinetic energy, which can then be used to do work.
