Answer:
The value is 
Explanation:
From the question we are told that
The emitted frequency increased by 
Let assume that the initial value of the emitted frequency is
Hence new frequency will be 
Generally from Doppler shift equation we have that
![f_1 = [\frac{ v \pm v_o}{v \pm + v_s } ] f](https://tex.z-dn.net/?f=f_1%20%3D%20%20%5B%5Cfrac%7B%20v%20%5Cpm%20v_o%7D%7Bv%20%5Cpm%20%2B%20v_s%20%7D%20%5D%20f)
Here v is the speed of sound with value 
is the velocity of the sound source which is 
because it started from rest
is the observer velocity So
Generally given that the observer id moving towards the source, the Doppler frequency becomes
![f_1 = [\frac{ v + v_o}{v + 0 } ] f](https://tex.z-dn.net/?f=f_1%20%3D%20%20%5B%5Cfrac%7B%20v%20%2B%20v_o%7D%7Bv%20%2B%200%20%7D%20%5D%20f)
=> ![1.016 = [\frac{ 343 + v_o}{343 } ] * 1](https://tex.z-dn.net/?f=1.016%20%20%3D%20%20%5B%5Cfrac%7B%20343%20%20%2B%20v_o%7D%7B343%20%7D%20%5D%20%2A%201)
=>
Answer:
θ = 4.716 10⁻⁶ rad
Explanation:
In order for the releases to be considered separate, they must meet the Rayleigh criterion that establishes that the maximum diffraction of one star must coincide with the first minimum of the diffraction pattern of the second star.
We use the diffraction equation for a slit
a sin θ = m λ
The minimum occurs at m = 1
sin θ = λ / a
Since the angles in these systems are very small, we can approximate the sine to its angle in radians
θ = λ / a
The telescope has a circular aperture whereby polar cords should be used, which introduces a constant number
θ = 1.22 λ / a
Let's calculate
θ = 1.22 518 10⁻⁹ / 13.4 10⁻²
θ = 4.716 10⁻⁶ rad
Answer:
it Farther then it seems
Explanation:cause it value
d = 0.221 mm is the spacing (in mm) between the two slits..
here,
wavelength = 589 nm
D = 150 cm = 1.5 m
y = 4 mm
then ,
y = mλD/d
for m = `1
0.004 = 589*10^-9 * 1.5/d
d = 2.21*10^-4 m
d = 0.221 mm
slit spacing is 0.221 mm
The sesmic characteristics of a train depend on the speed of the train, the distance between the wheels, and the hardness of the ground beneath the rails.
Philadelphia attack efficiency aims to improve spacing It continues to lag despite offseason moves, and Harden could have single-handedly fixed these issues.
In a typical hydrogen bond, as atoms move further up the energy ladder, The distance between the energy levels decreases. For Scientists Working at Such Small Scales, these “charging times” are likely candidates for the cause of the distance effect.

Answer:
Energy is proportional to the square of the amplitude
Explanation:
The energy of a certain wave is defined using its magnitude.
The two quantities are related directly. This means that as the amplitude of the wave increases, its energy increases and vice versa.
Energy is directly proportional to the square of the magnitude of the wave. This means that:
If we have new amplitude = 2 * old amplitude
We will have new energy = (2)² * old energy = 4 * old energy
Hope this helps :)
