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.
Had to look for the options and here is my answer.
I can say that it would be ten times as much of the Sun's radiation would strike if the Earth did not have its atmosphere.

Check out pages 804-808 in the Glencoe Earth Science textbook provided by PennFoster. That way you can learn about the answer. :)
Answer:
394.26 m
Explanation:
t = Time taken
u = Initial velocity
v = Final velocity
s = Displacement
a = Acceleration due to gravity = 9.8 m/s²
Total time taken by the stone to reach the ground is 4.49+4.49 = 8.97 seconds
The times are equal so,
The height is 394.26 m
