Answer:
The wave velocity is 1.3736
Explanation:
A plot of inverse of wavelength (λ) versus frequency (f), can be analyzed as follows;
The vertical axis will be 1/λ and the horizontal axis will be f
slope = (Δ1/λ)/(Δf)
= 1/(fλ)
∴ 1/(fλ) = 0.728
From wave equation, V = fλ
where;
V is the wave velocity
f is the frequency of the wave
λ is the wavelength
1/(fλ) = 0.728
1/(V) = 0.728
V = (0.728)⁻¹
V = 1.3736
Therefore, the wave velocity is 1.3736
In will most likely decrease its speed.
hope this helps.
Answer:
m = 1.99 kg = 2 kg
Explanation:
The moment of inertia of a bicycle rim about it's center is given by the following formula:
where,
I = Moment of Inertia of the Bicycle Rim = 0.21 kg.m²
r = Radius of the Bicycle Rim = Diameter of the Bicycle Rim/2
r = 0.65 m/2 = 0.325 m
m = Mass of the Bicycle Rim = ?
Therefore,
<u>m = 1.99 kg = 2 kg</u>
