Explain why some solar eclipses are total and some are annular.

Some solar are eclipse are total and some are annular because the eclipse are not a total circle so, at the different phase of year the moon and the sun are away from the earth at different degree.

Every occurring eclipse of sun are not considered as total solar eclipse. The moon are sometimes too small for covering the entire disk of the sun. And the annular eclipse are only happen when the moon covers the entire area of the sun.    

they are non-matter

explanation:

they are non-matter. basically, any type of energy or any abstract concept is an example of something that does not matter. other examples include dreams, magnetism, radio, and hate

gpe = mass x gravity constant x height or… gpe = mgh

where… mass: measured in kilograms (kg)

gravity: gravity constant on earth = 10.00 m/s2

height: measured in meters (m)

gpe: measured in joules (j) or kilojoules (kj)

how do you solve gpe?

gravitational potential energy (gpe) is the energy an object has because of its position above the. ground.

gpe = mass x gravity constant x height or… gpe = mgh.
