Yes, time for an object in motion relative to a stationary observer appears to pass slower.
An object that appears to stay in place is likely stationary relative to the observer. This can occur when an object is not moving in relation to the observer's frame of reference, creating the perception that it is fixed in place.
The Doppler effect is observed when the straight-line distance between the source and observer is changing.It makes no difference which one thinks it is stationary and which one thinks it is moving, and there is no pointin starting that argument. The fact is that each of them is moving in the other's frame of reference, and that isthe only statement that can apply truthfully to the situation.
When the source of a sound is moving towards a stationary observer, the pitch of the sound will appear higher (increased frequency). When the source is moving away from the observer, the pitch will appear lower (decreased frequency). This phenomenon is known as the Doppler effect.
True. When the source of a sound is moving relative to a stationary observer, the pitch of the sound appears to change due to the Doppler effect. If the source is moving towards the observer, the pitch is heard higher, and if the source is moving away, the pitch is heard lower.
Yes, time for an object in motion relative to a stationary observer appears to pass slower.
There is really no such thing as an absolute stationary point. By convention one can be picked as any point in the observer's frame of reference (i.e. any point stationary relative to the observer).
true
If the ball were simply dropped, the person dropping the ball and a stationary observer should see the same thing.

For the sound from a source not to be shift in frequency , the radial velocity of the source to the observer must be zero : that is the source must not be moving towards or away from the observer

The apparent motion of an object can vary depending on the motion of the observer. This is due to the concept of relative motion, where the perception of an object's movement is influenced by the observer's own motion. For example, if the observer is moving towards an object, the object may appear to move faster than if the observer is stationary.
The apparent change in the frequency of a sound emitted by a moving object as it passes a stationary observer is called the Doppler effect. As the object moves towards the observer, the observer perceives a higher frequency (higher pitch) than what is actually emitted. Conversely, as the object moves away from the observer, the perceived frequency is lower than the actual frequency emitted.
Yes. The observer frequency fo= f( v + vo)/(v -vs) where f is the signal frequency, v is the speed of wave and vo is the speed of the observer towards the signal and vs is the speed of the signal toward the observer.
