Why would it be innapropriate to dimension to a feature on a surface that is not perpendicular to the line of sight?
couple of reasons.... if you are drawing and dimensioning with a computer program the dimension will be inaccurate... If it is mechanical drawing then the fabricator would not have enough information to accurately measure the component. ie a circle turned a few degrees away from perp. would appear to be an ellipse. and may actually dimension that way

Why must electric field line be perpendicular to equipotential surfaces?
If the field lines were not perpendicular to the surface, then they could be decomposed into components perpendicular and parallel to the surface. But if there is an E-field along the surface, the surface is no longer an equipotential.
How many dimension does a surface have?
2
What surface is 90 degrees to a horizontal surface?
Perpendicular
What is dimension of surface area?
squared units of length.
What is the line perpendicular to a mirror's surface?
The normal (ray).

Why the dimension of surface tension is MLT-2?
The dimension of surface tension is MLT-2 because it is defined as the force acting perpendicular to a unit length of interface between two fluids. The force per unit length has units of force/length, which can be expressed as MLT-2.
What is a line perpendicular to a surface called?
The line perpendicular to a surface at a point is called the normal

What surface is 90 degrees to a horizontal surface?
Perpendicular
A line perpendicular to a surface?
Would be at at 90 degrees to the surface, in other words at right angles. So a line which was perpendicular to a horizontal surface would be vertical.
What is the 'normal' to a surface?
The normal to a surface is an imaginary line that is perpendicular to the surface at a specific point. It indicates the direction that is perpendicular to the surface and is used in geometry and physics to determine angles of incidence and reflection.
What is the angle between ray that strikes a surface and the perpendicular to that surface at the point of contact?
The angle between the ray that strikes a surface and the perpendicular to that surface at the point of contact is known as the angle of incidence. It is measured from the ray to the perpendicular line and is important in determining how light is reflected or refracted at that surface.
Why does pressure force acts perpendicular to the body?
If that force is not perpendicular to the surface, then there is a component of the force that's parallel to the surface. That component would move fluid around, until there were no longer any force parallel to the surface ... and the whole force would again be perpendicular to the surface.
What is the perpendicular force exerted by a surface pressing against an object called?
The perpendicular force exerted by a surface pressing against an object is called normal force. This force is perpendicular to the surface and acts in the opposite direction to the force applied by the object.
What is the name of the line drawn perpendicular to the surface where light ray strikes?
A normal line is the name of the line drawn perpendicular to the surface where a light ray strikes.
