Is sound energy mechanical

Sound is the medium vibration transmission, sound is the mechanical wave, transmits is the vibration this kind of mechanical movement, certainly transmits is the mechanical energy!
Sound energy is actually kinetic energy of medium vibration and potential energy of interaction. Sound energy is of course mechanical energy!

Electricity can be converted into mechanical energy, internal energy, light energy, sound energy and so on. What determines why electricity can be converted?

Energy is conserved. We all know that the reason why electricity can be transformed into various forms is that there is a medium. It can be transformed into various kinds of energy through various machines

How does solar energy transform into sound energy and light energy
It's short and urgent

First, solar cells are used to convert light energy into electrical energy, then circuits and sound generators are used to convert electrical energy into mechanical energy (sound wave), and electric lamps are used to convert electrical energy into light energy
At present, there is no direct conversion of solar energy into sound waves
Solar energy is light energy. You don't need conversion. You can use optical fiber to direct sunlight to the place you need

Energy conversion of Ampere force
It is said in the book that the work done by Ampere force makes the electric potential energy and mechanical energy transform into each other. In this way, when the electrified wire moves in the magnetic field, the electric potential energy is reduced. What is the change in the amount of charge and current?
Why does the electric potential energy decrease? If the electric field force does positive work, the electric potential energy will decrease. F = bil is also related to B
Is that energy conversion and magnetic field energy change?

Electric potential energy and mechanical energy are transformed into each other
It's something like a charged ball
An electrified wire moves in a magnetic field (of course, it consumes electric energy)
It is correct that only when the electric field force does positive work can the electric potential energy be reduced
Magnetic energy
