Ear Canal.
Explanation:
Sound waves enter the auricle and travel through a narrow passageway called the ear canal, which leads to the eardrum.
Answer: The new moon phase occurs when the Moon is directly between the Earth and Sun. A solar eclipse can only happen at new moon. A waxing crescent moon is when the Moon looks like crescent and the crescent increases ("waxes") in size from one day to the next. This phase is usually only seen in the west.
Weight of motorcycle on the moon = mg
Here, g= 1.622 m/s²
So, W = 250 * 1.622 = 405.5 Kgm/s² = 405.5 N.

Answer: 26,8 s</h2>
Explanation:
If we are talking about an acceleration at a constant rate , we are dealing with constant acceleration, hence we can use the following equations:
(1)
(2)
Where:
is the final velocity of the plane (the takeoff velocity in this case)
is the initial velocity of the plane (we know it is zero because it starts from rest)
is the constant acceleration of the plane to reach the takeoff velocity
is the distance of the runway
is the time
Knowing this, let's begin with (1):
(3)
(4)
(5)
Substituting (5) in (2):
(6)
Finding
:
This is the time needed to take off
To solve this problem, apply the concepts related to the relationship given between the centripetal Force and the Weight.
The horizontal force component is equivalent to the weight of the car, while the vertical component is linked to the centripetal force exerted on the car, therefore,


Equating both equation we have that,


Rearranging to find the angle we have that,

Our values are given as,




Therefore the minimum angle will be 11.53°
