g The angular size of the Moon when viewed with the unaided eye and through a telescope (both from Earth) is, respectively, 0.60° and 11°. If the focal length of the objective is 50 cm, determine the focal length of the eyepiece.

graph slopes whilst gas cools, then it is flat whilst conensation to liquid happens, the coolong liquid then graphs as a slope when it solidifies graph is flat
