In a mechanical solenoid, current is applied to a coil, allowing a contact to close (either by a plunger moving to make contact, OR by a hinged/pivoted contact to move to make contact) to complete a circuit and activate a device, such as an ignition/starter.
In a solid-state device, there are no moving parts, other than electrons, being routed through diodes, etc., to complete a circuit

Mechanical solenoids use a mechanical plunger or lever to actuate and move components, while solid-state solenoids rely on electrical signals to control the movement without physical contact. Solid-state solenoids typically have faster response times and higher efficiency compared to mechanical solenoids. Additionally, solid-state solenoids are less prone to wear and tear due to the absence of moving parts.
Mechanical waves require a medium (such as air, water, or a solid material) to propagate, while non-mechanical waves can travel through a vacuum, such as electromagnetic waves. Mechanical waves involve the transfer of energy through the vibration of particles in the medium, while non-mechanical waves involve the transfer of energy in the form of oscillating electric and magnetic fields.
Filtration, distillation, evaporation, and centrifugation are common methods used to separate mechanical mixtures. Filtration involves passing a mixture through a porous barrier to separate solid particles from a liquid. Distillation uses differences in boiling points to separate liquids based on their vapor pressures. Evaporation involves heating a mixture to evaporate the liquid component leaving behind the solid. Centrifugation uses high-speed spinning to separate components based on differences in density.
Yes, mechanical waves require a medium, such as a solid, liquid, or gas, for transmission. This is because the energy of a mechanical wave is carried through the oscillations of particles in the medium. Without a medium, such as in a vacuum, mechanical waves cannot propagate.
A transverse wave is called a mechanical wave because it requires a medium (such as air, water, or a solid) to propagate. The wave energy is transferred through the medium by causing particles to oscillate perpendicular to the direction of the wave's motion. This mechanical interaction between particles is what characterizes transverse waves.
One major difference is the medium of propagation. Electromagnetic waves do not require a medium (can travel through vacuum) while mechanical waves require a medium (such as air, water, or solid material) in order to propagate.
