I don't know I will try to find and answer you back

Answer 2

Dear Student,

◆ Answer -

θ = 0.5183°

● Explaination -

Let θ be the solid angle subtended by moon at any point on earth.

# Given -

d = 3474 km =

x = 384000000 m = 384000 km

# Solution -

Angle of parallax is given by -

θ = d / x

θ = 3474 / 384000

θ = 0.009047 rad

θ = 0.5183°

Thus, the solid angle subtended by moon at any point on earth is 0.5183°.

Hope this helps you...
