Answer:
option C
Explanation:
given,
Temperature of the surface = 6000 K
using formula to calculate 
is the maximum wavelength emission in meter.
T is the temperature in kelvin.
the wavelength is in Visible range
The Correct answer is option C
Answer:
Explanation:
The diffraction pattern is given as
Sinθ = mλ/ω
Where m=1,2,3,4....
Now, when m=1
Sinθ = λ/ω
Then,
ω = λ/Sinθ
The width of the central bright fringe is given as
y=2Ltanθ. From trigonometric
Then,
θ=arctan(y/2L)
Given that,
y=0.052m
L=0.55m
θ=arctan(0.052/2×0.55)
θ=arctan(0.0473)
θ=2.71°
Substituting this into
ω = λ/Sinθ
Since λ=544nm=544×10^-9m
Then,
ω = 544×10^-9/Si.2.71
ω = 1.15×10^-5m.
The answer in this question is 44.7533 mphGiven information which we denote I as the distance of the automobile between the farmhouse, and S = the distance past the intersection of the highway and the road.
Then I^2 = 5^2 + s^2. Taking the derivative of both sides of this equation yields 2I(ds/dt) = 2s(ds/dt), so (dl/dt) = s(ds)/I(dt). When the automobile is 7 miles past the intersection we have;dl/dt = 55√(7/5^2 +7^2) and gives us the answer of approximately 44.7533 mph
