Answer:
Explanation:
F = ma
a = F/m
a = (200.0 + 150.0 - 100.0) / 91.0
a = 250.0/91.0
a = 2.7472527...
a = 2.75 m/s²
V = f x lamda
Wave speed = frequency x wavelength
2x1 = 2 so wave speed = 2m/s
Let me know if you have any questions
From among the choices provided, the better choice is the upper-case letter '<em>T </em>'. That symbol can conveniently be used to represent the words "true" or "truth", which is exactly the reason that it is the better choice for a response, since the complicated statement at the beginning of the question is completely true in its every detail, nuance, jot and tittle.
