This is known as the focal length.
The general equation linking the focal length (f) to the distances of the object (u) and the image (v) from a lens is 1/u + 1/v = 1/f
Convex, bulged at the centre of the lens, has the properties to converge the incoming Electro magnetic rays to a particular point. Where as a concave lens diverge the incoming radiation.
Focal length
Right at the center - as with any figure that is sufficiently symmetric.
Freefall is caused by the gravitational attraction of the earth which accelarates every body towards its centre.
Of course not.It varies. Gravitatinal accelaration(g) indirectly propatinal to squared value of distance from centre of earth. g=GM/(R^2) G=universal gravitatinal constant M=mass of earth R=distance from centre
distance between the centre of two parallel cylinderin the sine bar
From the centre of Albury to the centre of Wodonga is a distance of 5.53km.
They can be vertical, horizontal or sloped and they are always equal distance apart from each other never intersecting. Circles can be parallel to each other when they are concentric with different diameters but sharing the same centre.
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
The average centre-to-centre distance from the Earth to the Moon is 384,403 km
Gravity causes each point on the outside of the planet to be a roughly equal distance from the gravitational centre.
A sphere intersected by two parallel planes equidistant from its centre, An ellipsoid intersected by two parallel planes equidistant from its centre, A uniform hyperboloid intersected by two parallel planes equidistant from its centre, A torus with a wedge removed, A cylinder.
According to the AA the distance by road is 122.7 miles or 197.5 kilometres. This distance is from town centre to town centre.
Centre national d'enseignement à distance was created in 1939.
Latitudes are parallel lines around the earth, parallel with the equator and marking the same distance from the equator. They are referred to as the angle made at the centre of the earth, from the equator to the point in question. The poles are at ninety degrees from the equator, so the maximum angle for any parallel of latitude, is 90 degrees. The equator is at zero.
This distance is called the 'radius'.
Half the distance from the wall to the centre of the luminaire, as the distance there is between luminaires. e.g if the distance between luminaires horizontally is 3m then the distance to the centre of the luminaire from the wall is 1.5m. If the distance between the luminaires vertically is 5m then the distance to the centre of the luminaire from the wall is 2.5m
