A bolt of lightning have enough energy to toast 1,00,000 slices of breadâ€¦..

Electric fields between two parallel plates are uniform in strength except at the edges

A desk weighs 500 N with gravity applying that force downward. If he apply 275 N upward force and a friend applies 275 N upward force the net force applied will 50N .

If two charged spheres touch each other add the charges and divide by two to find the final charge on each sphere.

All charge changes result from the movement of electrons not protons (an object becomes positive by losing electrons)

Diffuse reflection occurs from dull surfaces while regular reflection occurs from mirror type surfaces

1.Ionized gases conduct electric current using positive ions, negative ions and electrons

2.Electric fields all point in the direction of the force on a positive test charge.

Weight (force of gravity) decreases as you move away from the earth by distance squared.

Mass and inertia are the same thing.

A photon is a particle of light {wave packet}.
