Answer:
a) L = 1,923 m
, b) L = 0.012 m
Explanation:
This is a resonance problem, if the tube is open at both ends it has a
a maximum in each one, the waves must fulfill the relationship
λ = 2L / n
Where n is an integer and L the length of the tube
Let's use the ratio of the speed of sound
v = λ f
v = 2L f / n
L = v/2f n
The fundamental frequency corresponds to n = 1
L = v / 2f
a) for the smallest frequency
f = 89.2 Hz
L = 343 / (2 89.2)
L = 1,923 m
b) for the highest frequency
f = 13.9 kHz = 13.9 10³ Hz
L = 343 / (2 13.9 10³)
L = 12.338 10⁻³ m
L = 0.012 m
The Federal Deposit Insurance Corporation is a United States government corporation providing deposit insurance to depositors in U.S. commercial banks and savings institutions. The FDIC was created by the 1933 Banking Act, enacted during the Great Depression to restore trust in the American banking system
Answer:
a) d₁ = 247.8 μm
d₂ = 205.3 μm
b) d₂ = 20.53 x 10⁻⁵ m = 205.3 μm
Explanation:
a)
The formula for Michelson Interferometer is derived to be:
d = mλ/2
where,
d = distance moved
m = no. of fringes
λ = wavelength of light
For JAN, we have following data
d = d₁
m = 818
λ = 606 nm = 606 x 10⁻⁹ m
Therefore,
d₁ = (818)(606 x 10⁻⁹ m)/2
<u>d₁ = 24.78 x 10⁻⁵ m = 247.8 μm</u>
For LINDA, we have following data
d = d₂
m = 818
λ = 502 nm = 502 x 10⁻⁹ m
Therefore,
d₂ = (818)(502 x 10⁻⁹ m)/2
<u>d₂ = 20.53 x 10⁻⁵ m = 205.3 μm</u>
b)
The resultant displacement can be found out from the difference between both displacement. And the direction of resultant displacement will be the same as the direction of greater displacement. Therefore,
Resultant Displacement = Δd = d₁ - d₂
Δd = 247.8 μm - 205.3 μm
<u>Δd = 42.5 μm (in the direction of JAN)</u>
Answer:
A large elliptical
Explanation:
A S0 type galaxy is a large elliptical.
Answer:
17.78 m/s
Explanation:
Average speed is found by simply dividing the distance travelled by the time that it took to finish the trip. It's measured in meters per second (m/s), so first convert the quantities.
1 km = 1000 m, so 16 km is 16000 m
0.25 hours is 15 minutes. Since 1 minute is 60 seconds, then 15 minutes must be 900 seconds.
Thus:
average speed = total distance/total time = 16000 m / 900 s = 17.78 m/s
