Line perpendicular to the surface.
The contact angle is the angle in which the liquid interface meets the solid surface. The contact angle should be as small as possible to have an effective penetrant material.
the answer is a stapler a stapler has an acute angle
Calculating distances and anglesYou can calculate the distance between any two points you select. The following information is displayed:The distance between the points, measured in drawing units.Their angle in the xy plane.Their angle measured from the xy plane.The change (delta) in the x, y, and z distances between the two points.To calculate the distance between two points and their angleDo one of the following:Choose Tools > Inquiry > Distance.On the Inquiry toolbar, click the Distance tool .Type distance and then press Enter.Specify the first point.Specify the second point.
By controlling the amount of gate current !!
If the angles of two triangles are equal the triangles are similar. AAA If you have three angles on both triangles these must be equal for the triangles to be similar. SAS If you have an angle between two sides and the length of the sides and the angle are the same on both triangles, then the triangles are similar. And SSS If you know the three sides
The angle of incidence is the angle between the incident ray and the normal (perpendicular) to the reflecting surface.
The angle of incidence it he angle at which the incident ray stikes the plane of the surface.
It is the angle between an incident ray and the perpendicular to the surface at the point of incidence.
The angle of incidence is defined as the angle between the incoming light and the line that is normal to the surface at the point where the light 'hits' the surface. The reflectrion angle is the same as the incidence angle. If the angle between the incident ray and the mirror ray is 50, then the angle of incidence is half of this. That is, 25 degrees.
It's called the angle of reflection. 38 degrees. The angle between the incident ray and the reflected ray is 19 degrees + 19 degrees = 38 degrees. The angle of incidence and the angle of reflection are measured with respect to the surface normal, or a line drawn perpendicular with the surface the light is reflecting off of.
yes
The incident ray and the normal .
That happens when the incident ray is perpendicular to the surface at the point of incidence.
Oblique incidence applies to rays that are incident at some angle OTHER THAN at right angles (90 degrees) to the surface on which they are incident. Vertical incidence IS at right angles.
The ray of incidence is the light ray hitting the mirror plane and the ray bouncing off is the reflection ray. An incident ray is a ray of light that strikes a surface. The angle between this ray and the perpendicular or normal to the surface is the angle of incidence
That's the angle of " incidence ".
The angle between the incident ray and the normal is known to be angle of incidence The angle between the reflected ray and the normal is said to be angle of reflection By the law, the angle of incidence = angle of reflection
