Explanation:
Check attachment for solution
Answer:
ossicles (comprising of hammer, anvil, and stirrup)
Explanation:
The hammer, anvil and stirrup are also known as the malleus, incus, and stapes, respectively which are the part of the middle ear.
They transmit the sound vibrations from eardrum to cochlea by a level mechanism. The generate mechanical advantage by multiplying the force over a shorter distance from the input of a smaller force at a larger distance.
Answer:
Space junk, or space debris, is any piece of machinery or debris left by humans in space. It can refer to big objects such as dead satellites that have failed or been left in orbit at the end of their mission. It can also refer to smaller things, like bits of debris or paint flecks that have fallen off a rocket.
Answer:
Both reaches equilibrium simultaneously.
Explanation:
Given that,
First stretch spring= 20 cm
Second stretch spring = 10 cm
Two equal masses are suspended from identical spring.
Their forces constants are equal time period for oscillation
Using formula of time period
Where, T = time period
m = mass
k = spring constant
Time period independent of amplitude.
Hence, Both reaches equilibrium simultaneously.
Initial velocity(u) = 11.2 m/s.
Final velocity(v) = ?
acceleration(a) = 10.2 m/s²
Using kinematic equation v = u + at
v = 11.2 + 10 x 8 = 11.2 + 80 = 91.2 m/s.
Therefore final velocity is 91.2 m/s.
