The event that happens to sound waves from an object as it moves toward you is The pitch gets higher because of an increase in wavelength.
<h3>What is sound waves?</h3>
Sound waves refer to a form of transverse wave that compress and vibrate while travelling from one medium to another thereby transferring energy.
Therefore, The event that happens to sound waves from an object as it moves toward you is The pitch gets higher because of an increase in wavelength.

The north arrow of the compasses will all point to the south since opposite poles attract. I have put an example picture below.
For the horse shoe magnet the magnetic field line will also go from north to south. I have put a picture of this below
The answer is B. Domain
When the atoms point to the same direction and aligned with one another, It will form a magnetic material in which magnetization is in a uniform direction
This alignment usually happens stimunaleously due to exchange interaction that caused by a response to an external field.
Aster's final position from her initial position is 63 m approximately. She will head north west direction to return to her initial position
<h3>
What is Displacement ?</h3>
Displacement is the distance travelled in a specific direction. It is a vector quantity.
Given that a person walks first 70 m in the direction 37° north of east, and then walks 82 m in the direction 20° south of east, and finally walks 28 m in the direction 30° west of north.
a) Let P be the Aster's final position from her initial position?
We can use bearing by using Cosine formula to solve this question.
P² = 70² + 82² - 2 × 70 × 82 cos 73
P² = 4900 + 6724 - 11480 cos 73
P² = 11624 - 3356.43
P² = 8267.57
P = √8267.57
P = 90.9 m
P = 90.9 - 28
P = 62.9 m
We can get the angle by using Sine rule
82/ sin Ф = 90.9 / sin 73
sin Ф = 0.8627
Ф =
(0.8627)
Ф = 59.6°
Ф = 60°
b) She will head north west direction to return to her initial position
