Angular acceleration is the rate of change of angular velocity over time. In SI units, it is measured in radians per second squared (Rad/s2), and is usually denoted by the Greek letter alpha (α).[1]

It is a telescope on an equatorial drive (one axis parallel to the Earth's axis). An electric motor drives the other axis at 15 degrees per hour to follow an object as it moves across the sky.
The light ray will bend towards the major axis, aiming for the focal point.
The meaning of MNA is Magnetic Neutral Axis. It can be defined as the axis along which no emf is produced, as the armature conductors moves parallel to the field flux lines. The scope of how it works is to great an explanation for this site.
Milller's Theorem is used to simplify a circuit for circuit analysis. Instead of one impedance, which connectes two non-grounded nodes, Miller's Theorem allows this impedance to be broken down into two parallel impedances. One impedance can be seen as Z/(1-A) and the other impedance can be simplified to Z/(1-(1/A)). In this case, Z was the value of the original impedance, and A is the gain of the amplifier being analyzed.
The Opposite Sides Parallel and Congruent Theorem states that if a quadrilateral has a pair of opposite sides that are parallel and congruent, then the quadrilateral is a parallelogram.
This is known as parallel axes theorem. Statement: If IG be the moment of inertia of a body of mass M about an axis passing through its centre of gravity, then MI (I) of the same body about a parallel axis at a distance 'a' from the previous axis will be given as I = IG + M a2
In physics, the perpendicular axis theorem (or plane figure theorem) can be used to determine the moment of inertia of a rigid object that lies entirely within a plane, about an axis perpendicular to the plane, given the moments of inertia of the object about two perpendicular axes lying within the plane. The axes must all pass through a single point in the plane.Define perpendicular axes , , and (which meet at origin ) so that the body lies in the plane, and the axis is perpendicular to the plane of the body. Let Ix, Iy and Iz be moments of inertia about axis x, y, z respectively, the perpendicular axis theorem states that[1]This rule can be applied with the parallel axis theorem and the stretch rule to find moments of inertia for a variety of shapes.If a planar object (or prism, by the stretch rule) has rotational symmetry such that and are equal, then the perpendicular axes theorem provides the useful relationship:
the moment of inertia of a body about a given axis is equal to the sum of its moment of inertia about a parallel axis passing through its centre of mass and the product of its mass and square of perpendicular distance between two axis Iz=Ix+Iy

The moment of inertia of a cube depends on what its axis of rotation is. About an axis perpendicular to one of its sides and through the centre of the cube is (ML2)/6. Where M is the Mass of the Cube and L the length of its side. Due to the symmetry of the cube, you can find the Moment of Inertia about almost any other axis by using Parallel and Perpendicular Axis Theorems.

Parallel lines are parallel. Proof they have same slopes
It is used to reduce the complexitiy of the networkAnswerNorton's Theorem is one of several theorems necessary to solve 'complex' circuits -i.e. circuits that are not series, parallel, or series parallel.
y=-2.5 is parallel to the x axis. The equation of the x axis is y=0
Parallel lines never intersect and remain equal distance from each other
Any line with the equation [ x = any number ] is parallel to the y-axis.
