P₁V₁ / T₁ = P₂V₂ / T₂
1.6 × 168 /255 = 1.3 × V₂ / 285
V₂ = 1.6 × 168 × 285 / (1.3 × 255)
V₂ = 231.095
The final volume = 231 cm³
Answer:
a) t = 3.6 s
b) d = 23 m
c) v = 13 m/s
Explanation:
Let t be the time the accelerating rider rides
the distance she travels is
d = ½3.6t²
the distance for the other cyclist is
d =3.5(t + 3)
½3.6t² = 3.5(t + 3)
1.8t² - 3.5t - 10.5 = 0
quadratic formula, positive answer
t = (3.5 + √(3.5² - 4(1.8)(-10.5))) / (2(1.8))
t = 3.575786...
d = ½(3.6)(3.575786²) = 23.015...
v = 3.6(3.575786) = 12.8728...
To solve this problem it is necessary to apply the related concepts to string vibration. This concept shows the fundamental frequency of a string due to speed and length, that is,

Where
v = Velocity
L = Length
Directly if the speed is maintained the frequency is inversely proportional to the Length:

Therefore the relationship between two frequencies can be described as


Our values are given as,

Therefore the second frequency is

The frequency allocation of 329Hz is note E.
