Hello,
I'd be glad to help.
Momentum = (mass) times (speed)
= (75 kg) x (18 m/s)
= 1,350 kg-m/s .
Hope this helps
Answer:
Explanation:
The period of a physical pendulum is:
The length of the leg is approximately the height of the person:
The period is:
Explanation:
Archimedes' principle states that the upward buoyant force which is exerted on body when immersed whether fully submerged or partially in the fluid is equal to weight of fluid which body displaces and this force acts in upward direction at center of mass of displaced fluid.
Thus,
<u>Weight of the displaced fluid = Weight of the object - Weight of object in fluid.</u>
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.

Answer: 46.5 m/s
Explanation:
Momentum = mass(m) × velocity (v)
momentum of car = momentum of truck
1210 × v = 2250 × 25
v = 46.5 m/s
