Answer:
angular width is 0.10 degree
Explanation:
Given data
width = 340 nm
separation d = 790 nm
λ = 520 nm
to find out
how many maxima and width of a spectral line
solution
we know for maxima formula is
m λ = dsinθ
and we know here sinθ is between 0 and 1
so we can say
d is greater than m λ
and
m ≤ d / λ
m ≤ 790 / 520
m ≤ 1.52
its mean we have 3 maxima i.e. 0 , 1 and -1
and
for 1st order m = 1
so mλ = dsinθ
λ = dsinθ
θ = sin^-1 ( λ/d) ................................1
and angular width is
θ = λ/ Nd cosθ
θ = dsinθ / Nd cosθ
θ = tanθ /N ...............................2
so here put θ in 2 equation
angular width = tanθ/N
angular width = tan ( sin^-1 ( 520/790) ) / 500
angular width = tan 41.16 / 500
angular width = 1.7484 × 
× 180/π
angular width = 0.10 degree
Answer:
from Late Latin convectionem
Explanation:
The internal combustion engine has been criticized for ages for its negative effects on human health as well as the deterioration that it has caused to the environment with the release of Carbon Dioxide (CO2). However, to settle the skeptics, studies have been conducted to prove the environmental benefits of the internal combustion engine.
According to an article written by Dr. Dwight R. Lee, an Economist at the University of Georgia, livestock is responsible for 18% of the greenhouse gases that cause global warming, a far higher statistic than the contribution made by automobiles and aircrafts. The internal combustion engine began replacing horses as a source of power in the early 1900s, which started replacing the outputs from animals with exhaust from tailpipes.
<h3><u>Given :- </u></h3>
- Length of the rectangular wire, L=0.3 m
- Width of the rectangular wire, b=0.2m
- Magnetic field strength, B=0.8 T
- Velocity of the loop, v =12 m/s
- Induced Current, I = 3 A
(I) Emf developed,E in the loop is given as:
I = E/R
R = E/I
where
- R = resistance
- E = Induced EMF
- I = Current
(ii) The direction of current induced is from P to Q which is given by B × V vector . It may also be explained by Lenz law. Since magnetic field is from S to N . The fingers of the right hand are placed around the wire so that the curling of fingers will show the direction of the magnetic field produced by the wire then the thumb points in the direction of current flow which is from P to Q.
