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.

The magnetic force experienced by the proton is given by
where q is the proton charge, v its velocity, B the magnitude of the magnetic field and
the angle between the direction of v and B. Since the proton moves perpendicularly to the magnetic field, this angle is 90 degrees, so
and we can ignore it in the formula.
For Netwon's second law, the force is also equal to the proton mass times its acceleration:
So we have
from which we can find the magnitude of the field:
I would rather be hit by the deflated ball because it wouldn't hurt as bad because it wouldn't have a lot of weight to hurt me in anyway
Answer:
B. The presence of an unbalanced force(e.g friction) causes a moving object to stop.
Explanation:
As the friction is that force that can stop the sled upon reaching the levelled surface so the option b is correct.
