They are balanced b/c the motion is constant
Answer:
Value of magnitude of acceleration will be 
Explanation:
It is given that when a stone is dropped it takes 2.2 sec to reach the ground
(a) As the stone is dropped from the top of building
So its initial velocity 
will be 0 m /sec
(b) As the stone is free falling and there is no external force applied on it so its acceleration will be equal to acceleration due to gravity
So value of magnitude of acceleration will be equal to
The three parts of the ear anatomy are the outer ear, the middle ear
and the inner ear. The inner ear is also called the cochlea. (‘Cochlea’
means ‘snail’ in Latin; the cochlea gets its name from its distinctive
coiled up shape.)
The outer ear consists of the pinna, ear canal and eardrum
The middle ear consists of the ossicles (malleus, incus, stapes) and ear drum
The inner ear consists of the cochlea, the auditory (hearing) nerve and the brain
Sound waves enter the ear canal and make the ear drum vibrate. This
action moves the tiny chain of bones (ossicles – malleus, incus, stapes)
in the middle ear. The last bone in this chain ‘knocks’ on the membrane
window of the cochlea and makes the fluid in the cochlea move. The
fluid movement then triggers a response in the hearing nerve.
