Which of these is an example of electrical energy being converted to mechanical energy? Sunlight used by plants in photosynthesis
Ceiling fan
Lightning striking the ground
Flashlight

Ceiling fan

Explanation:

In a ceiling fan, electrical energy is converted to mechanical energy. Electrical energy provides the power that drives the motor in the fan.

The motor works by the interaction between electric current and magnetic fields.

Therefore, the electric current causes the mechanical motion of the motor.

As the current passes between the magnetic field, a turning force is set upThe movement of the motor drives the fan blades. This is mechanical energy. Mechanical energy is expressed as the motion of a body.

The  grandmother cell  is a hypothetical  neuronthat represents a complex but specific concept or object.[1]  it activates when a person "sees, hears, or otherwise sensibly discriminates"[2]  a specific entity, such as his or her grandmother. the term was in use at least as early as 1966 amongst staff and students in the department of experimental psychology, university of cambridge, england. a similar concept, that of the  gnostic neuron, was proposed two years later
