Electromagnetic deflection is used because it can create greater deflection angles of the electron beam compared to electrostatic deflection.
You can find the deflection in a flight of stairs using hand calculations by first measuring all angles and lengths. These can then be entered into a formula which calculates deflection based on these variables.
Sand dunes that are at right angles to the wind are called Transverse Dunes. They form with weak winds and an abundant supply of sand.
Snell's law stipulates that the ratio of the sines as regards the angles of incidence in addition to that of refraction is a constant influenced by the media.
A straight line with a constant slope. But the reverse is not true. A straight line with a constant slope only means constant speed in the radial direction. The velocity may have components at right angles to the radial direction that are changing.
To enable constant velocity. It keeps a shaft turning through a range of angles.
Meridians of constant longitude cross parallels of constant latitude. Parallels of constant latitude cross meridians of constant longitude. At each intersection of a meridian and a parallel, the lines are perpendicular (form 90° angles).
A circle has no angles because its circumference is a path tyraced put by a point moving at a constant distance from the centre, and an angle is defined as the junction of two straight lines. A circle has one edge - its circumference.
A pair of quadrilaterals, of any kind, will be similar if their sides are in some constant ratio - other than 1 - and their angles are the same.
Yes, if apply at the right angles the acceleration can change the object's current direction without effecting its speed.
An ellipse is a conic section, a curving line which is the path of a point that moves in such a way that the sum of its distance from two fixed points is constant.... so no - there are not 4 straight angles in an ellipse, nor any straight bits at all.
