Answer:
Explanation:
When the object fall from the top floor it moves with parabolic motion.
This particular case is a horizontal motion of a projectile, so the equation that relates the distance and the time in the y-axes is:
Here: y is the final height, it will be 0, because the object touch the ground.
y₀ is the initial height, it will be h and v₀ in y-axis is zero, because it has a horizontal initial velocity.
So we have:
(1)
We know that the velocity at the x-axes remains constant, then we have:
x is the distance from the base of the building
we can solve it for t and put on (1).
Solving it for x we will have:
But

Answer:
eardrum is the correct answer
hope this helps ❤️
Explanation:
Sound waves enter the ear canal and cause the eardrum to vibrate. Three small bones transmit these vibrations to the cochlea. This produces electrical signals which pass through the auditory nerve to the brain, where they are interpreted as sound.
Answer:
Gravitational force is directly proportional to the distance between objects.
The best and most correct answer among the choices provided by your question is the second option or letter B. It is carried on FM wave by modulating its frequency.
In telecommunications and signal processing, frequency modulation<span> (</span>FM<span>) is the encoding of information in a carrier wave by varying the instantaneous </span>frequency<span> of the wave.
