Answer:
what are u asking there isnt a question
The pitch of a sound is decreased, when a sound source approaches the observer.
<u>Explanation:</u>
Pitch is nothing but it is a property that helps to determine whether the sound is high or low. Doppler effect helps to understand this concept easily. The pitch of the sound is mainly calculated based on the frequency of the sound wave arose from the sound source.
As the wellspring of sound waves moves toward an audience, the sound waves draw nearer together, expanding their recurrence and the pitch of the sound.
Answer: Option C
C) accelerated vertical motion and constant horizontal motion.
Explanation:
If there is no air resistance then during the projectile movement the only force that causes an acceleration is the gravitational force.
We know that this force produces an acceleration of 9.8 m / s ^ 2 in the projectile.
As the gravitational force attracts the object towards the earth, then the acceleration that this force produces is always in the vertical direction. In the horizontal direction the object is not accelerated (because there is no air resistance).
Therefore the correct answer is option C.
"accelerated vertical motion and constant horizontal motion".
