Diameter of moon,`" "D=3.4xx10^(6) m`
Distance from earth,`" "r=3.8xx10^(8) m`.

If we approximate its straight line diameter as an arc length, then the angle `theta` subtended at the earth at the earth by the moon is

The diameter of the moon is 3.5 xx 10^(3)km and its distance from the earth is 3.8 xx 10^(5)km . It is viewed by a telescope which consists of two lenses of focal lengths 4m and 10 cm. Find the angle subtended at eye by the final image.

The diameter of the moon is 3.5 xx 10^3 km and its distance from the earth is 3.8 xx 10^5 km . It is viewed by a telescope which 10 cm . Find the angle subtended at the eye by the final image.

The diameter of the moon is 3.5xx10^(3)km and its distance from the earth is 3.8xx10^(5) km . It is seen by a telescope having the focal length of the objective and the eye-piece as 4m and 10cm respectively. The diameter of the image of the moon will be approximately

The diameter of the moon is 3.5xx10^(3)km and its distance from the earth is 3.8xx10^(5) km . It is seen by a telescope having the focal length of the objective and the eye-piece as 4m and 10cm respectively. The diameter of the image of the moon will be approximately

The diameter of the moon is 3.5xx10^(3)km and its distance from the earth is 3.8xx10^(5) km . It is seen by a telescope having the focal length of the objective and the eye-piece as 4m and 10cm respectively. The diameter of the image of the moon will be approximately

The diameter of the moon is 3.5 xx 10^3 km and its distance from the earth is 3.8 xx 10^5 km . The diameter of the image of the moon seen by a telescope having focal length of the objective and the eyepiece as 400 cm and 10 cm respectively will be

The moon is at a distance of 3.84xx10^8 m from the Earth. If viewed from two diametrically opposite points on the Earth, the angle subtended at the moon is 1^@ 54 '. What is the diameter of the Earth?
