Answer:
The magnitude of induced emf is 5.4 V
Explanation:
Given:
Magnetic field 
T
Area of loop 
Time take to reduce loop to zero 
sec
To find induced emf we use faraday's law,
Induced emf is given by,
Here minus sign shows lenz law, for finding magnitude of emf we ignore it.
Where 
Put the value of flux and find induced emf,
V
Therefore, the magnitude of induced emf is 5.4 V
Answer:
C. Sleep Apnea
Explanation:
Sleep Apnea is when someone who snores and stops breathing while sleeping
Answer:
Explanation:
The general consensus is that it's more “natural” to define distance (meter) and time (second) and as base units, and derive velocity a the ratio between them. ...

Answer:
Explanation:
For constructive interference in thin films by reflected light , the condition is
Path difference = 2μd = odd multiple of λ / 2
Where μ is refractive index of water , d is thickness of water medium and λ
is wavelength of light
λ = 4μd or 4μd / 3 or 4μd / 5
= 4 x 1.33 x 400 nm = 2128 nm
or 2128 /3 = 709.33 nm
or 2128 /5 = 425.6 nm
For destructive interference ( dim reflection )
2μd = multiple of λ = λ or 2λ or 3λ
2 x 1.33 x 400 nm =1064
or 1064 x 2 = 2128 nm
or 1064 x 3 = 3192 nm.
