3. Alveolar Trill
/r/

4. Alveolar Tap
/ɾ/

5. Explanation
The alveolar trill and the alveolar tap are consonantal sounds, used in some spoken languages.
Both the alveolar trill and the alveolar tap are coronal consonants which is a type of consonant articulated with the flexible, front part of the tongue. 
In the majority of Indo-European languages, the alveolar trill is at least occasionally allophonic with the alveolar tap [ɾ], particularly in unstressed positions.

7. Features
For alveolar trill [r], its manner of articulation is trill, which means it is produced by directing air over the articulator so that it vibrates.

8. For alveolar tap [ɾ], its manner of articulation is tap, which means it is produced with a single contraction of the muscles so that the tongue makes very brief contact.

9. * All the features are similar except for the manner of
articulation.
The phonation is voiced.
They are oral consonants, which means air is allowed to escape through the mouth only.
They are central consonants, which means they are produced by directing the airstream along the center of the tongue, rather than to the sides.

10. The place of articulation is alveolar, which means that they are articulated with either the tip or the blade of the tongue at the alveolar ridge.
