1Draw a quick sketch of the object.
2Draw an arrow showing every force acting on the object.
3<span>To calculate the net force, add any vectors acting on the same axis (x and y), making sure to pay attention to the directions.
Hope this helps :)

Answer: A) <u>Either source or listener must be moving.</u>
Explanation:
Frequencies can shift if an observer is moving relative to the wave’s source. This type of shift is called the Doppler effect (often used to analyze sounds). Think about the sound you hear when a police siren passes you and drives away; as the car increases its distance from you, the pitch of its sound becomes lower. This is because each wave is emitted from a greater distance, causing the wavelength to spread out or increase relative to you, the listener.

The average speed is 10 m/s.
Explanation:
The motion of the object is divided into two parts.
In the first part, the object covers a distance of

In a time interval of

In the second part, the object is a t rest, so it covers a distance of

In a time interval of

The average speed for the trip is given by the ratio between the total distance and the total time taken, therefore:
