To solve this problem it is necessary to apply the concepts related to optical magnification (is the process of enlarging the apparent size, not physical size, of something.). Specifically the angular magnification of an optical telescope is given by

Where,
Focal length of the objective lens in a refractor
Focal length of the eyepiece
Our values are given as
71cm
2.1cm
Replacing we have



Therefore the magnification of this astronomical telescope is -33.81
No fire uses oxygen sparks and flammable wood or whatever you choose to burn
When the temperature increases, the intermolecular forces between the molecules of a liquid become weaker, and some bonds break easily. Thus as temperature increases, the surface tension of a liquid decreases.
True. Since Inertia states this law, we are bound to believe greater mass = greater resistance in change of motion
