Normal force, weight, Kinetic friction, and air resistance are a few I think of the top of my head.
I hope this helps
Answer:
a)The electric Field will be zero at the point between the sheets
b)
c)
Explanation:
Let
be the surface charge density of the of the non conducting parallel sheet.Let consider a Gaussian surface in the form of of cylinder such that its cross-sectional is A . Then there will be flux only due to cross sectional area as the curved sectional is perpendicular to the the electric field so the Electric Flux due to it is zero.
Now using Gauss law we have, E be the electric Field at the distance r from the sheet then

The Field will be away from the sheet and perpendicular to it.
a) The Electric Field between them

b)The Electric Field to the right of the sheets

c)The Electric Field to the left of the sheets

Answer:
Are you talking about aurora borealis?
Explanation:
Answer: D) a stone lies on the ground
Explanation:
Potential energy this is defined as the mechanical energy, energy stored, or energy created by the position of an object. Example; energy possessed by a ball while hanging at the top of a steep hill when about to roll down is called a potential energy. This is same as a stone which lies in a floor.
" An object<span> at rest stays at rest and </span>an object <span>in motion stays in motion with the same speed and in the same direction </span>unless acted upon<span> by an </span>unbalanced force<span>."- Newtons first Law of Motion
Also, velocity is the speed of something in a given direction (So, 50mph North is an example of velocity)</span>
