No, two equipotential surfaces cannot intersect. These are surfaces where the gradient of potential is zero always.
(4) symmetric, (7) alternate interior angles
no each statement should have a reason/explanation for it to be true
Yeah
corresponding angles
self siphonage
There is no reason because the statement for which you are seeking a reason is patently FALSE. Consider a pentagram, for example.
They don't have solid surfaces.
reduce air resistance
To focus the light toward the front.
Generally speaking, the reason why a metal gasket leaks is because the problems in the joint exceed the capabilities of the gasket. This can include improper surface finishes, foreign material between the surfaces, erosion of the surfaces, and gaps between the surfaces.
Pluto does not have the same orbital plane as the other 8 planets. That is one reason why the origin of Pluto is debated.
Waves. The rolling and abrasion of sand flowing over the surfaces takes oof sharp edges and rough areas, eventually grinding and polishing to rounded surfaces.
The reason Mercury droplets are spherical is because they do easily wet other surfaces. For this reason, mercury forms spheres, which have the smallest possible ration of surface area to volume.
I'm guessing you mean a microwave oven. There's often a bit of splatter when heating food, and slick surfaces are easier to clean. Apart from that, no reason. They would work just as well matte or drab.
No reason at all.
Both are correct, in different context and with different sentence structure. For example: For this reason she left early; but This is the reason why she left early.
There is no particular reason why the outer planets are gas and the inner planets are rock, but the outer planets have icy cores because they are all far away from the sun.
