The distance
of
d
Given:. D: 1:496 X 10"m
0:1920"
To find a Care length)
are length - radius to
D
③ The sun's angular diameter is measured to
the Sun from the Earth is 1.4964 lov
What is the diameter of the Sun. 06.​

Answer 1

Answer:

Given, θ=1920"=

3600

1920

=0.53

o

=0.53×(π/180)=0.0093 radian

and D=1.496×10

11

m

Here, tanθ=d/D

As θ is very small so tanθ∼θ

So, diameter of the sun is d=Dθ=1.496×10

11

×0.0093=1.39×10

9

m
