C. The outer ear has to collect the sound waves and lead them to the middle ear.
Explanation:
In the process of hearing, the first thing that happens is that sound waves enter the outer ear through a passage called "auditory canal" that reaches the eardrum.

The answer is that it is 1.5 amps
To calculate the acceleration of the skater on the rough ice, we use the equation

Here, u is initial speed when she hits the patch of ice and its value is 10 m/s and v is final speed when she left the patch of ice and its value is given 7.0 m/s and s is the width of patch of ice and its value is 5.0 m.
Substituting these values in above equation we get,
.
Thus, the acceleration of skater on the rough ice is
