the diagram down shows the path of a ship that sails at a constant velocity of 42 m/s east. what is the ship's position when it reaches point C, relative to the starting point, A, if it sails from point B to point C in exactly 1.5 s?

explanation:

v=uf/(u-f)

= 5.-10/(5+10) convex lens has negative focal length

and 1and 1

the working equation for the angular size is the product of the physical size and 360 degrees divided by the product of two pi and distance from earth. the minimum size would be 0.559 degrees while the maximum size would be 0.49 degrees.
