Answer:
The best method of investigation that a scientist can use in an investigation of twins separated at birth - as in the case of Trinna and Suzanne - is a case study.
Explanation:
The case study is a qualitative research strategy that can be used in both biology, psychology and sociology, even combining these disciplines. Take an observed phenomenon, sometimes unique, looking for an explanation based on the examination and the elaboration of hypotheses.
Trinna, despite being an identical twin, developed a shorter stature and habits different from Suzanne, probably due to her growth in different environments.
The objective of the case study would be to demonstrate how the growth of twins in different settings may have caused physical and cultural differences in these identical twins.

Answer:
The drum skin oscillates 20 times per second
Explanation:
The frequency of a note is dependent on the mechanical activities that occur when it is produced. A drum is beaten in this case. The oscillation of the drum skin transfers sound waves to the air particles which move at the same frequency before reaching our ears.
If the frequency of the sound wave is 20 Hz this means that the wave is oscillating 20 times in one second. For the drum to produce such a sound, the skin must have been oscillating at the same frequency of 20 oscillations per second too.
