Answer:

Explanation:

Electromagnetic and gravitational forces have equations that clearly describe them.

Electromagnetic      Fe = K q₁ q₂ / r²

Gravitational            Fg = G m₁ m₂ / r²

Analyzing these expressions a bit we can see some things in which they are EQUAL:

    • They depend on the inverse of the squared distance

    • They are long range, they become zero In the infinite

    • They are proportional to a system constant, in one case the charge and in the other the mass

We can also observe some DIFFERENCES:

     • Gravitational always attractive, the electric can be attractive or repulsive depending on the charge

    • When we calculate their magnitudes the electric force in 10 40 times greater than the gravitational

    * The electric force can be zero if the charge is zero, the gravitational force can never be zero

Sound waves that enter the external acoustic meatus eventually encounter the __________, which then vibrates at the same frequen
7nadin3 [17]

Answer:

tympanic membrane (eardrum)

Explanation:

The sound waves spread through the air and reach the outer ear, into which they penetrate through the ear canal. In doing so, they stimulate the eardrum, which closes the inner end of the duct. By vibrating this membrane, the vibration of a chain of ossicles located in the middle ear is induced. These ossicles transmit their vibration to the oval window, which is a membranous structure that communicates the middle ear with the cochlea of ​​the inner ear. When the oval membrane moves, it moves the liquid (perilymph) that fills one of the three cavities of the cochlea generating waves in it. These waves mechanically stimulate the sensory cells (hair cells) located in the organ of Corti, within the cochlea in the central cavity, the middle ramp. This cavity is filled with a liquid rich in K +, endolymph. The cells embedded in the endolymph, change their permeability to K + due to the movement of the cilia and respond by releasing a neurotransmitter that excites the nerve terminals, which initiate the auditory sensory pathway.

evablogger [386]

Monoammonium phosphate effectively smothers the fire, while sodium bicarbonate induces a chemical reaction which extinguishes the fire. Fire extinguishers with a Class C rating are suitable for fires in “live” electrical equipment.
