Answer: 40.84 m
Explanation:
Given
Radius of the disk, r = 2m
Velocity of the disk, v = 7 rad/s
Acceleration of the disk, α = 0.3 rad/s²
Here, we use the formula for kinematics of rotational motion to solve
2α(θ - θ•) = ω² - ω•²
Where,
ω• = 0
ω = v/r = 7/2
ω = 3.5 rad/s
2 * 0.3(θ - θ•) = 3.5² - 0
0.6(θ - θ•) = 12.25
(θ - θ•) = 12.25 / 0.6
(θ - θ•) = 20.42 rad
Since we have both the angle and it's radius, we can calculate the arc length
s = rθ = 2 * 20.42
s = 40.84 m
Thus, the needed distance is 40.84 m
Answer:
Explanation:
Given that, the wavelength is 3.45m
λ=3.45m
Frequency is 4.65×10^2Hz
F=4.65×10^2Hz
Speed is given as
V=Fλ
Then,
V=4.65×10^2× 3.45
V=1604.25m/s
The speed of sound in fresh water is 1604.25m/s
