Explanation:

If you want to know the six basic ones they are, chemical, electrical, radiant, mechanical, thermal and nuclear energy. Hope this helps!

If talking about forms of energy, the answer would be:

Kinetic, potential, and chemical energy

If asking for types, the answer could be:

Nuclear, Electrical, and Thermal

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.
