from pole position

Two boys are standing on either side of a pole that is h = 160 m long. Their angles of elevation of the top of the pole measures 30°20′ and 45°30′. Find the distance between the two boys. (The position of the boys and the foot of the pole ..

All distances are measured from the pole of the mirror. Distances measured in the direction of the incident ray are positive and the distances measured in the direction opposite to that of the incident rays are negativ..

The emf of a cell is positive when one moves in the direction of increasing potential (i.e., negative pole to positive pole) through the cell and is negative when one moves from positive to negativ..

After the centrioles reach their positions corresponding to the two opposite poles, the chromosomes arrange themselves upon the equator of a spindle, which is formed in the cell by delicate cytoplasmic threads radiating from the centrioles. Each sister chromatid is attached at ..

Leclanche cell of an outer glass vessel which is filled with saturated ammonium chloride (NH 4 Cl) solution. In it there stands a zinc rod and porous pot 'P' containing a carbon rod 'c' which is packed round with a mixture of manganese dioxide (MnO 2 ) and powdered carbon. Wet Leclanche Cell T..

It is the intersection between the ions of the solute at low concentrations. It is not much at low concentrations the inter-ionic cone is very less, but at high concentrations it is appreciable. fig 5.1 The negative ion is pulled to the negative pole because it is surrounded by ..

The dipole pattern of earth's magnetic field is disturbed due to solar winds. Solar winds are a stream of charged particles coming from the sun. These particles ionise the atmosphere above these poles which display a light high up in the atmosphere. This phenomenon occurring in the arctic..

A pictorial representation that gives the direction of the magnetic field at various points in a magnetic field is called a map of the magnetic field Let us now map the magnetic field by using a compass Fix a sheet of paper on a drawing board Place a bar magnet on the sheet of paper T..

In a spherical mirror, the distance of the object from its pole is called the object distance (u). the distance of the image from the pole of the mirror is called the image distance (v). You already know that the distance of the principal focus from the pole is called..

It consists of two dees or D-shaped metal chambers D 1 and D 2 . The dees are separated by a small distance. The two dees are perpendicular to their plane. P is the position where the ion source is placed. The dees are maintained to a potential difference whose polarity alternates with ..
